[Evaluation of blood grouping in ABO and Rh systems in health facilities in Benin]

The goal of this work is to assess the modalities of blood typing achievement in Benin with the view of their improvement.

On the basis of a questionnaire including the detailed operative process, a prospective investigation has been achieved in public and private health centers laboratories.

It came out that the execution of ABO and Rh blood typing took place globally on the fringe of the standards. We note that 72.4% of the private laboratories and 48.9% of the public ones lacked at least one equipment and 51.3% at least one material for blood withdrawal; 38.2% of the laboratories did not respect blood withdrawal standards; 1.32% of the laboratories applied the 4×2 rule. The assessment revealed that respectively 10.8% and 30.7% of the blood centers and non-blood centers achieved the globular test solely; the same 40.5% and 46.2% used reagents of different brands. Anti-A1 and anti-H sera, and A1 and A2 red cells were not available in any laboratory. More than 64% of laboratories have senior technicians and biomedical analysis engineers but only 6.6% of the laboratories were directed by biologists, and 9.2% of the laboratories function with only one technician.

Instead of some assets, the laboratories assessment noted important non-conformities we ought to raise as a matter of urgency. It is a challenge whose resolution must give blood transfusion centers a reference position relatively to blood grouping when facing blood typing difficulties.
