It is feasible to issue phenotype-matched blood to patients without any need of pre-transfusion testing, therefore eliminating mismatched transfusions for most patients.
It is also responsible for undertaking its own range of tests which are concerned with blood grouping, antibody screening and identification and pre-transfusion testing.
Pre-transfusion testing is limited to ABO grouping, an infection screen (malaria, Hepatitis B and HIV), haematocrit assessment and mixing of donor and recipient samples to visually assess for evidence of agglutination.
Association of factors with transfusion were tested by the χ test.
The undertaking of pre-transfusion tests is an essential task before the administration of a blood transfusion.
Pre transfusion HIV and HCV tests have been performed in 58.5 % of cases, 95%% CI [55.6-61.5], and post-transfusion tests in 30.5 % [28.5 35.5] of cases.
Only 19.5% [16.6 22.6] of recipients, not known to be dead 6 months after transfusion, have had both pre and post-transfusion tests.
This paper presents an electronic system and an interface application, able to perform all pre-transfusion tests quickly, easily, in safe conditions, and with high reliability, even in remote locations.
My research work in information technology has also included studies of PDAs with drug reference guides; a controlled trial of smart intravenous infusion pumps in ICU patients; the impact of decision support on improving transfusion practice and testing electronic prescribing standards in the outpatient setting.
In another case, individual screening was triggered, and NAT was done, but before the screening results were received, a granulocyte unit was released for transfusion use; testing results later showed that the WNV load was sufficient for detection by NAT of pooled and individual blood samples (16 ).
