Optical detection of red blood cells captured on biochips for RH1 compatibility control at the patient’s bedside
Résumé
Every year, several millions of red cell concentrates are transfused. For each of them, a pretransfusional compatibility test is performed. In France, an ABO compatibility test at the patient’s bedside is performed, but rhesus compatibility is not yet checked. However, rhesus antigens are very immunogenic and could lead to Rh incompatibility or Rh disease. Rh incompatibility occurs when a woman with Rh-negative blood type is exposed to Rh-positive blood cells.
