Laboratory Handbook | Department of Diagnostic Medicine | Jewish General Hospital | 2012-2013 Page 11

Remember, please complete the requisition legibly.

Laboratory Handbook | Department of Diagnostic Medicine | Jewish General Hospital | 2012-2013 Page 12

Specimen ID & Rejection 1. Specimen containers must be

labelled legibly

Full name

Date of Birth

MRN or RAMQ number

Where applicable date, collection site,

start stop times

2. The Laboratory reserves the right to

reject unacceptable samples such as:

Samples which may have leaked during

transit

Unlabeled specimen container

Inadequate or illegible information on

the requisition form

Blood gas syringes with needles

attached

Sample obtained or transported

incorrectly, or received in an incorrect

container

Grossly contaminated exterior of sample

container or biohazard bag

Misaligned secondary labeling (one example

of which is shown on the left) means extra

work and reduced efficiency in the

laboratory. Properly applied secondary label

is shown on the right. Please do not cover

the entire tube, allow enough space

lengthwise to visualize the blood

Samples received by the laboratory are potentially infectious. All laboratory staff are aware of this

fact and are trained in the handling of potentially infectious substances. However, the laboratory

reserves the right to reject samples which are received in a condition which would unduly

increase the staffs' risk of becoming infected, e.g. broken or leaking sample tubes, sample for

blood gas with needle attached, grossly contaminated exterior of containers.

Laboratory Handbook | Department of Diagnostic Medicine | Jewish General Hospital | 2012-2013 Page 13

Biohazard specimen bags

1. Tubes containing blood must be placed

a biohazard specimen bag.

2. Urine specimens and other biological

fluids must be placed in separate

biohazard bags. i.e. Do not put a tube

of blood and a urine specimen in the

same bag.

3. Ensure that the urine containers are

tightly closed before being placed in the

bags.

4. The requisition accompanying the

specimen should be folded and placed

in the pouch on the outside of the bag.

Do not put the requisition in the same

compartment as the specimens.

5. The label identifying the patient must be

placed directly onto the specimens and

not on the bag. Specimens identified

only on the bag, will be regarded as not

identified and will be rejected by the

laboratory.

6. Make sure the bags are tightly closed

(same principle as "Ziploc" bags).

Laboratory Handbook | Department of Diagnostic Medicine | Jewish General Hospital | 2012-2013 Page 14

Specimen Delivery

1. Blood samples:

Make sure tubes are properly identified

Place in a plastic biohazard bag

Only use one bag per patient

Do not glue or staple the bag (do not

use elastic bands)

2. Urine or stool samples:

Make sure containers are properly

closed and identified

Place in a plastic biohazard bag, (1

urine specimen per bag)

Do not glue or staple the bag (do not

use elastic bands).

3. When sending specimens to the

Hospital from an outside location,

place all bags in a solid polystyrene

box.

The use of a refrigerant bag to keep

specimens cool during transport is

recommended, but the specimens

should not be in direct contact with the

refrigerant bag.

4. Label the box:

Apply a "Bio Hazard" sticker and

Clearly identify the institution sending

the specimens including address.

Samples are generally received in the

Laboratory via the following means:

A. Inpatient samples:

The messenger service. Samples are

picked up from the Nursing Stations.

Nurse aids and orderlies also deliver

specimens in certain situations (e.g.

STAT samples).

Pneumatic tube, delivers samples from

the Emergency Department (Red Unit,

Blue Unit and "Resuscitation") as well as

the Oncology Department. The tube

operates 24 hours a day. Specimens on

ice may also be sent via the pneumatic

tube, however the ice must be sealed in

a separate biohazard bag and then

placed with the sample into a second

biohazard bag and sealed. The

requisition slip must be placed in the

pouch of the second biohazard bag.

Microbiology samples may also be sent

via the pneumatic tubes, except blood

culture bottles which are delivered via

messengers.

Samples for the Blood Bank are

delivered by orderlies and messengers.

There is no pneumatic tube in Blood

Bank.

Laboratory Handbook | Department of Diagnostic Medicine | Jewish General Hospital | 2012-2013 Page 15

STAT samples are delivered by hand to

the front window of the Laboratory.

B. Outpatient samples:

Samples from the Test Center, PAT,

Hematology Clinic and Endocrine Clinic

are picked up every 20 minutes and

delivered to the Laboratory.

Samples from the Herzl Family Practice

Center and ENT, Urology, Eye, Geriatric

and Methadone clinics are picked up at

approximately 09h00, 11h00, 13h00 and

15h00 and delivered to the Laboratory.

Samples from the Infectious Diseases

clinic are picked up every 30 min to 1

hour and delivered to the Laboratory.

CLSC's, Nursing Homes, etc make their

own arrangements for the samples to be

delivered to the Laboratory.

C. Research specimens: Person

responsible for the study arranges for

the samples to be delivered to the

Laboratory.

Laboratory Handbook | Department of Diagnostic Medicine | Jewish General Hospital | 2012-2013 Page 16

Blood

1. Most biochemistry assays are performed on whole blood, plasma or serum. These samples

are obtained by collecting blood into tubes which may or may not contain various additives. It

is generally more economical and easier to collect blood into evacuated tubes.

2. Certain assays are very specific regarding the sample type and acceptable sample tubes are

indicated the Test Catalogue.

3. When collecting whole blood or blood samples which require plasma for analysis, the sample

tube containing anticoagulant must be gently inverted 6-8 times. This must be performed

immediately following collection to ensure the sample remains unclotted.

Please note: vigorous shaking will cause hemolysis and possible test interference. If required,

the sample may be centrifuged immediately and the plasma separated.

4. When serum is required, the sample must be allowed to clot for 20 - 30 min following

collection, before centrifugation. Clotting is generally complete within this time period but

may be prolonged if the patient is anticoagulated. Centrifugation, before clotting is complete,

will cause sample probe blockage and spurious results.

5. When multiple samples tubes are to be collected, the "order of draw” on the next page must

be adhered to in order to prevent contamination of serial tubes and consequent spurious

results.

6. Coagulation tubes (light blue top) MUST be filled to the indicated mark.

Never top-up a tube by transferring blood from one tube to another.

Laboratory Handbook | Department of Diagnostic Medicine | Jewish General Hospital | 2012-2013 Page 17

Order of draw for venipuncture The following order is for all routine venipunctures methods (evacuated tube and winged collection set), regardless of the method used to collect it. MIX TUBES BY GENTLE INVERSION.

Order Color of tube Additive Mixing Instructions

1

Blood culture bottles:

aerobic then anaerobic

Aerobic = grey top Anaerobic = orange top

Minimum amount: 5 ml in each bottle; optimal amount: 8-10 ml

Mix 5 – 10 times See procedure for details

regarding pediatric culture bottles

2 Gold

Silicon gel Mix sample 5-10 times

3 Red tube (no gel)

None DO NOT MIX USE ONLY for cryoglobulins Sample should be clotted

4

Citrate Sodium citrate Tube must be full for coagulation

studies Mix gently 5-10 times

5

Green

Sodium or lithium heparin

Mix sample 5-10 times Discard sample if any clot is

present Lavender

or

6

Pink

K2 - EDTA Mix sample 5-10 times Discard sample if any clot is

present

The recommended order of draw when collecting more than one sample during a single venipuncture is as follows:

Blood culture tubes Non-additive tube (e.g. red stopper) Additive tube (e.g. lavender tube)

This order is critical for the following reasons:

Non-additive tubes are drawn before additive tubes to avoid additive contamination of the non-additive tube.

Cross contamination between different additive tubes lead to erroneous test results.

Laboratory Handbook | Department of Diagnostic Medicine | Jewish General Hospital | 2012-2013 Page 18

Results Reporting

As soon as test results are authorized in the

laboratory, they are available on the

laboratory computer terminals in the ward.

Hardcopies of in-patient results are printed

once a week and distributed to the wards.

Hardcopies of urgent results are printed on

the ward printer immediately after

verification.

Critical results phoned to the ward are also

printed on the ward printer following

verification.

When a patient is discharged, a cumulative

report of all the patient's results during that

stay is printed in Medical Records for

placement in the patient's hospital chart.

Outpatient results are printed daily and

mailed to the requesting clinician. The

laboratory also faxes results (replacing the

hardcopy) daily to certain clinics and doctors

who have arranged for this service with the

laboratory.

Whilst the laboratory performs internal and

external quality assurance throughout the

day, it is possible for random errors to

occur. Following technical validation it is

therefore possible for inaccurate results to

be released even though they have passed

through various checks and flags.

In this situation, the clinician is the best

person to detect these errors. Although

these errors are extremely rare, should the

situation arise where results do not agree

with the clinical condition, please contact the

laboratory and report the disagreement. We

will then be able to retest the sample if

possible and investigate a possible error.

Therapeutic Drug Monitoring

Therapeutic drug monitoring is most useful

when the drug in question has a low

therapeutic index and is used chronically.

Measurement may be of value in

assessment of compliance, therapeutic

dosing adjustment and confirmation of

clinical toxicity. It is important to note that

many factors may influence the

pharmacokinetics of a particular drug e.g.

protein binding, co-administration of other

drugs, pharmacogenetics.

Some patients may exhibit toxic effects at

concentrations less than the upper limit of

the therapeutic range.

Interpretation of a drug level is

dependant on the time the sample is

collected relative to the dosing time;

please indicate these parameters on the

requisition form.

1 Increases up to 6 days in renal impairment. 2 In renal failure half-life can be 24 hrs or longer. 3 Phenytoin does not obey first order kinetics at therapeutic concentrations therefore a true half-life cannot be calculated. In adults the apparent half-life is 18-36 hrs and in children 12-22 hrs. 4 In smokers half-life is 3 - 4 hrs, neonates and adults with CHF 20-30 hrs depending on degree of liver impairment. 5 In the elderly or those with renal impairment, half-life can be as long as 6 days.

Near patient testing

Glucometers are available on the wards.

The Accu-Chek Inform glucometers are

linked to the hospital computer system as

well as the laboratory information system.

Patients admitted to a particular ward will

appear on the Inform glucometers located in

that ward.

The laboratory is responsible for monitoring

the quality control of the devices.

Nursing staff are responsible for performing

the QC on the instruments.

Once a test is performed, the result is

available on the instrument. However, only

when the Inform glucometer is docked will

the results be transmitted to the LIS and

made available on the laboratory computer

terminals on the ward.

The laboratory provides training of nursing

staff and can be contacted at ext 5094. The

clinical nurse instructor or resource nurse on

each unit, who have been certified as

trainers by the laboratory, may also train

nursing staff.

General support for Accu-Chek Inform

glucometers is available at ext 5094; ask for

the person on-call for these devices.

In addition, near patient testing includes

fecal occult blood, urine pregnancy testing,

blood gas analysers, jaundice meter, and

activated clotting time.

Under Quebec Law, the laboratory is

required to supervise near patient testing.

The laboratory is currently producing

certification videos for near patient testing

and will include the above tests and online

certification for health care workers.

Glucose tolerance test (GTT or OGTT)

What is the glucose tolerance test? The glucose tolerance test measures the body's ability to metabolize glucose. Why is this test performed? The oral glucose tolerance test is generally performed to diagnose diabetes mellitus when fasting blood glucose is difficult to interpret. How to prepare for the OGTT? The test is generally performed 8 to 14 hours after an overnight fast. We suggest fasting from 22h00 and then present to the test center the following morning at 08h00. The test must be performed before 10:00 am for proper interpretation. We recommend bringing along a good book or other reading material, as you will be required to remain seated for 2 hours during the test. What does fasting mean? No caloric intake for at least 8 hours before your first blood sample is taken. During this period only water may be taken. Can I drink other liquids? You may drink only water (no tea, coffee, or other beverages) Can I take my medication? A number of medications can affect the test results, therefore, it is important to inform your health professional of all medications you are currently taking. You may be instructed to stop certain medications prior

to the test. When can I resume eating? The standard glucose tolerance takes 2 hours from the 1st blood sample. You will be able to eat after the last blood sample. What other precaution must be taken prior to test? You should maintain an unrestricted diet and activity for at least three days prior to the test. Do not engage in strenuous exercise for 8 to 14 hours before the first blood sample is taken. How is the test done? On the day of test, the following steps will be done: 1. A blood sample will be collected after

you arrive and register at the test center. 2. You will be asked to drink a sweet liquid

containing 75 g of glucose. It should be drunk slowly over 5 min.

3. You should remain seated at the test center during the test, without smoking.

4. A second blood sample will then be collected after 2 hours.

5. You may then eat and drink. What affects the Test? 1. Acute stress (surgery, infection,

emotional cause, or fever) or Vigorous exercise

2. Certain medications, as well as alcohol. 3. Low carbohydrates diet in the days just

before the test. 4. Vomiting during the test may also cause

inaccurate results.

Patient instructions for 24-Hour urine collection

NOTE: PLEASE USE URINE CONTAINERS PROVIDED BY THE HOSPITAL. URINE COLLECTED IN ANY OTHER CONTAINER WILL NOT BE ACCEPTED. 1. On the morning that you start collecting your urine, (eg. 9:00A.M.), empty your

bladder in the toilet and discard the urine. Note: The collection starts with an empty bladder.

2. At the start of the collection, record the start date and time on the label attached to

the container. At the end of the collection, record the finish date and time as well. 3. Collect ALL the urine for the rest of the morning, afternoon, evening and night, in the

container provided. 4. Make sure the lid is tightly closed and the spout is snapped in to avoid any spillage. 5. Take the container with you if you go out. 6. Keep the container in a cold place whenever you can. 7. The following morning, (ex. 9:00 A.M. the next day), empty your bladder and collect

the urine. This is the last urine to be collected. 8. Bring in all your collected urine, along with the requisition, to the

Test Centre (Room E-102), or to the Department of Diagnostic Medicine Department (Room D-136).

If you have any questions, please call 340-8222 extension 5094. REMEMBER: You will have to start again if any urine is missed during the 24 hour collection OR if the requisition does not accompany the collection upon delivery. CAUTION: The bottles marked CORROSIVE contain acid. In order to avoid acid burns, empty your bladder in a measuring cup first and then transfer the urine to the bottle. Rinse the measuring cup with water only after each usage. Do not wash with soap or detergent. Keep the container upright to avoid acid spillage or contamination of the bottle cap. In case of skin contact with acid, wash immediately with water (5 minutes).

We do not provide the measuring cup; one can be purchased at any grocery store, pharmacy or a dollar store.

Patient instructions for stool collection

(routine culture and Clostridium difficile)

Container: Sterile orange top

Sterile white container with spoon

To ensure that the best quality specimen is collected:

1. Stool must not be contaminated with urine or water from the toilet bowl.

2. The stool must be collected in the manner described below. Do not use toilet paper to

collect the stool sample.

3. The following medications might interfere with the results of the stool test, therefore you

should wait seven days before providing a specimen if you have taken any of the

following:

o Bismuth

o Magnesium ( e.g. Some antacids)

o Mineral oil

o Barium meal or Barium enema test

Procedure:

Collect the stool in the following manner;

1. Pass the stool sample directly into a sterile, wide mouth, leakproof container with a tight

fitting lid.

2. To prevent stool from mixing with water, place either an aluminum pie plate in the toilet

bowl, or place saran wrap over the toilet seat to collect stool sample.

3. With a cardboard stick or with the spoon provided in the white top container provided,

spoon out an egg sized portion and place it into the sterile container.

The following protocol is to be used for diagnosing Influenza. Influenza is diagnosed by viral culture or antigen detection.

Influenza is NOT diagnosed by a blood test.

The best specimen for viral detection in adults is a throat gargle. If this cannot be done (i.e.

intubated patients, patients with no gag reflex, patients with decreased level of consciousness or

severe dementia or unable to cooperate), then a deep nasal swab should be done.

Procedure for obtaining a throat gargle for Influenza virus detection

1. Use 2 mL of non-bacteriostatic saline (available in pink plastic unidose ampoules OR 2

mL can be aspirated from a single-dose vial of non-bacteriostatic saline for injection;

discard vial after use).

2. Place saline into sterile orange-topped specimen container

3. Ask patient to gargle with saline for 5 seconds (i.e. "count slowly to five") and then to spit

saline back into the container. Close container tightly.

4. Label specimen. Send specimen without delay to Microbiology, accompanied by a single

blue Microbiology requisition, and check off "viral culture" (specimen: throat gargle) and

also write in "Rapid Influenza Assay".

Procedure for obtaining a deep nasal swab for Influenza virus detection

1. Use the regular culture swabs.

2. Moisten culture swab first by placing it into the accompanying culture tube, which is

already filled with transport liquid in a mini-sponge. Leave swab in contact with mini-

sponge for 5-10 seconds.

3. Remove swab from culture tube, and place into posterior nostril of patient. Press against

nostril wall in a circular motion 3-5 times. Remove and place into other nostril and rotate

against nostril wall another 3-5 times. Place swab back into culture tube and close tightly

by pressing into place.

4. Label specimen. Send specimen without delay to Microbiology, accompanied by a single

blue Microbiology requisition, and check off "viral culture" (specimen: nasopharyngeal

swab) and also write in "Rapid Influenza Assay".

Fecal occult blood screening - Patient information

PURPOSE OF TEST To detect colorectal bleeding. HOW? By detecting blood in the stool that is invisible to the eye, but can be detected by a simple chemical reaction. WHAT TO DO? 2 easy steps: 1. For a period of 48 hours, and until all

stool specimens are collected, do not eat red meat, radishes, turnips, melons or horseradish. You may eat small quantities of chicken and tuna. For the same period of time take no aspirin or vitamin C. All these substances may contain blood-like material or cause the appearance of blood in the stool, and produce false results. During this testing period, eat plenty of cooked fruits and vegetables and whole grain cereals such as “All Bran.” These foods encourage bowel movements.

2. After a full 48 hours on the above diet, collect pieces of stool from the first 3 bowel movements. First Collection 1. Flip open slide 1 2. Use one stick to collect a sample from

stool 3. Apply a thin layer of stool on the

rectangle labelled A

4. Apply a second layer of stool on the rectangle labelled B

5. Close the cover flap 6. Discard the stick Second Collection 1. Flip open slide 2 2. Use one stick to collect a sample from

stool 3. Apply a thin layer of stool on the

rectangle labelled A 4. Apply a second layer of stool on the

rectangle labelled B 5. Close the cover flap 6. Discard the stick Third Collection 1. Flip open slide 3 2. Use one stick to collect a sample from

stool 3. Apply a thin layer of stool on the

rectangle labelled A 4. Apply a second layer of stool on the

rectangle labelled B 5. Close cover flap 6. Discard the stick NOTE: 1. Do not apply more than a thin smear,

the test result may be invalid 2. Do not expose slides to the heat,

sunlight, or fluorescent light. Keep it in cool, dark place.

3. Do not collect specimens during menstruation or hemorrhoidal bleeding.

3. Return the test card to the Test Centre.

Laboratory Handbook | Department of Diagnostic Medicine | Jewish General Hospital | 2012-2013 Page 52

Labeling of cytology specimens

1. All specimens must have a label affixed, pre-printed or handwritten, which supplies the following information: • Patient’s full name • Patient’s unique identifying number (RAMQ or MRN) • Site of specimen • Time of immersion into fixative. 2. To avoid mislabeled specimens, proper identification of the patient is necessary at the point of collection. Carefully verify the information on the admitted patient’s bracelet at bedside just prior to specimen collection. All outpatients are identified by asking the individual to pronounce his full name and date of birth. The information provided by the patient must exactly match the physician request, the laboratory requisition, and the specimen label prior to collection. 3. No collection containers should be pre-labeled. Containers should be

labeled directly at the patient-side immediately following collection. Immediately discard any unused labels to avoid mislabeling of the next patient. 4. Proper containers and fixatives for collection must be used. Using a wrong container or fixative may lead to erroneous results. 5. Where there is uncertainty in the identification of the primary sample or its condition, the laboratory may choose to process the sample after the requesting physician or person responsible for the primary sample collection takes the responsibility for identifying and accepting the sample, or for providing proper information, or all these. In such an instance, the signature of that person taking responsibility for the primary sample identification should be recorded on the request form and in the final report.

Transfusion service

Starting November 19th 2007, Transfusion Service will introduce a new requisition (F161 REV 09-07 - see attached).which will replace and incorporate our present 3 requisitions (F160, 161 and 162). On the above start date, the new requisitions will be available in Stores, your old requisitions are to be discarded and the new requisition put in place. In order to meet this CCHSA requirement, it is mandatory for both the requisition and specimen to include (see attached examples):

1) Patient Identification – label, addressograph or handwritten (Full Name/Hospital # or RAMQ (date of birth if RAMQ not available))

2) Date 3) Time 4) Phlebotomist’s initials

In order to facilitate the introduction of these mandatory requirements, there will be a transition period of one month. During this time, Transfusion Service will call the location stating that a notification form (see attached) is being faxed for the charge nurse. This notification form will indicate what mandatory information the patient’s requisition and/or specimen were missing. IMPORTANT: It should be noted that the mandatory information not indicated on the notification form is already enforced. If the requisition and/or specimen are received with any of the above information missing:

1) Specimen: If the patient’s name or number is missing the specimen will be rejected. Missing collection date and time can be completed however, the phlebotomist must come to the Transfusion Service to complete this or the specimen will be rejected. If there is an urgent need for blood, the protocol for uncrossmatched blood will be applied.

2) Requisition: if only the requisition is missing mandatory information, the phlebotomist must complete another requisition and have it hand delivered to Transfusion Service or the specimen will be rejected. If there is an urgent need for blood, the protocol for uncrossmatched blood will be applied.
