XXXX caused by an antibody to a low-prevalence antigen, anti-SARA.

@entity1 @entity648 @entity6570
BACKGROUND: The first case describing the SARAH (SARA) antigen occurred in 1990, in an Australian blood donor. @entity6570 ( @entity6570 ) due to anti-SARA has not been previously described. CASE REPORT: We report a case of @entity6570 in a multiparous female. The pregnancy was unremarkable except that she was involved in a seemingly minor motor vehicle accident at 25 weeks' gestation. Routine prenatal antibody screening was negative throughout the pregnancy. She presented at 37 weeks' gestation because of decreased fetal movements. Labor was induced and a 2702-g @entity1 male was delivered. The @entity1 's hemoglobin was 49 g/L and the @entity648 was 153   mol/L. RESULTS: Blood samples from the parents and @entity1 were referred to Canadian Blood Services National Immunohematology Reference Laboratory and subsequently to the Australian Red Cross Red Cell Reference Service. The father's and @entity1 's red blood cells were confirmed to be SARA positive, and the mother's plasma contained anti-SARA. CONCLUSION: The @entity1 was successfully treated with a double-volume exchange transfusion. This is the first example of @entity6570 associated with this antibody.
