Abstract
To evaluate the virological safety of blood components provided by the Niamey blood transfusion center after undergoing rapid tests. Samples found negative with rapid tests (n = 222) were screened by the Abbott Prism assay. Positive samples were confirmed by appropriate methods. Of 222 samples, nine (4.1%) were reactive for all markers. After confirmation, seven samples were positive (i.e., 3.2% false-negative results): five (2.3%) for the surface antigen of hepatitis B (HBsAg) and two (0.9%) for the antibody directed against the hepatitis C virus (HCV-Ab). No false negative results were observed for HIV-Ab (antibody directed against the Human Immunodeficiency Virus). The performance of the rapid tests used in Niamey to screen for transfusion-transmissible infections is not satisfactory, especially for hepatitis B and C. The use of more sensitive tests should be considered to minimize the risk of contaminating patients receiving blood components.
