Effect of transfusions on serologic testing for antibody to varicella
Medical and Pediatric Oncology
|January 1, 1986
Abstract:
Serologic testing of patients with acute lymphocytic leukemia for susceptibility to varicella was confounded by prior administration of blood products. Packed red cell transfusions produced fewer problems than plasma-rich transfusions. Seronegative individuals may be transiently seropositive for several weeks. Specimens submitted for serologic testing should be accompanied by information on recent receipt of blood products.
