Pilot evaluation of LR EXT sets of the Reveos automated blood processing system

The Reveos automated blood processing system is the only system developed till date, which can separate whole blood into components on complete automation. Their proprietary LR and NLR blood collection sets have their own advantages and disadvantages. Using LR sets, leukodepleted components can be prepared but individual platelet units cannot be prepared. Using NLR sets, individual platelet units can be prepared, but components are non-leukodepleted. The newly launched LR EXT with the apparent advantage of both LR and NLR sets have been evaluated in this pilot study.

Blood components prepared from 31 LR EXT sets were evaluated in this study in comparison with the National regulations and with components routinely prepared from LR and NLR sets.

Excluding under-collected and sero-reactive units, components prepared from 27 LR EXT sets were evaluated for their quality. QC of PRBC units prepared had a mean volume of 296.86 ml, Hct of 59.2 % and WBC count as low as 0.06 × 106 per bag. FFP units had a mean volume of 221.89 ml, mean Fibrinogen of 432.47 mg and FVIII levels of 98.13 IU per bag. PLT units had a mean volume of 73.07 ml, PLT count of 5.74 × 1010 and WBC count of 3.21 × 108 per bag.

The use LR EXT blood collection sets help in achieving adequate inventory of both LD-PRBCs and RDPs especially in blood centres with a lower daily collection rate.
