Define priority of bloodcomponents

Optimalisation of blood components:

Production of ALL components in MOST excellent quality is NOT possible, define priority:

- Plasma; quick separation, fast freezing to optimise quality. Freezing < 3 hr after separation

- Platelets, storage for 4 – 24 hours, optimal recovery of platelets, high quality.

-This choice of most important component together with method of preparation defines basic algoritms of processing, find acceptable consensus for all components.

Influencing the logistics of blood processing

External regulations:

- Fractionater; max. delay of freezing 3 hr

- GMP; different staf for different departments

Internal influences:

- Organisational priorities; lab and processing

- waste costs;

- work during late evening/night; personal costs

Different Reduction in Lymphocyte and Granulocyte content by removal of BC from fresh and O/N stored blood. (Z.Rácz, Hungary 1997)

- Results of separation: Manual (Q), Separator 1 =TACE(Q) and Separator 2=OPTIPRESS) were compaired with these variabels:

- Fresh blood and stored (O/N)

- Different sizes of BC taken

- Distribution of Lymphocytes/Granulocytes were investigated.

Top and Bottom separation:

- Simultanious transfer of Plasma and Red Cells.

- Buffycoat is NOT transferred

- Hard spin for maximal Plasma recovery, up to 4700g for 15 minutes.

Conventional Quadruple bag:

- Removal of plasma and BC from top of primairy bag.

- Transfer of SAGM through same tube.

- Quality of components influenced by storage of blood

- Platelet production with pooled Single BC or single Dilted BC

Results of the study:

- Stored blood gives better removal of leukocytes with equal volume of BC removed.

- 20-30 ml BC: Fresh Stored

- Manual Q: 45% 70%

- Auto Q: 60% 78%

- Auto TAB: 71% 82%

Platelet production

Platelet production from whole blood:

Triple bag conventional: Platelet Rich Plasma, to be separated by an additional spin in PC and PPP.

Quadruple bag conventional:

A: Diluted buffy coat to be separated by additional spin in PC and a waste residual BC.

B: 4 – 6 single buffycoats to be pooled together with a plasma (or additive solution), to produce a pooled random platelet concentrate. Buffycoats to be pooled within 24 HOURS

Basic Processing procedures

Platelet production from whole blood:

Quadruple TAB bag :

Diluted buffycoat to be separated by additional spin in PC and a waste BC. Better results as quadruple Dil BC

Triple TAB bag:

Single buffy coat to be pooled together with 4-6 and a plasma (PAS etc), to produce a pooled random platelet concentrate. Buffycoats to be pooled within 24 HOURS

Optimal separation logistics in Rotterdam (NL).

- Collection of blood: every day from 09:00 untill 21:00. The collected blood is stored O/N in a incubator of 22°C.

- Test samples of blood are tested during the night from 00:00 untill 07:00.

-Test results are used to release the collected blood before the processing starts at 08:00.

- Unsafe blood is processed separate of safe blood.

- Pooling of Buffycoats is always done with safe products, no waste of pools due to positive test results.

New posibility for TSF saving Platelets

Small centres, willing to pool BC, allowing them to have prestorage filtering conditions with pooling untill day 3 (or more) to optimise the logistics of the platelets.
