CMV indicates cytomegalovirus; SE, standard error; LR, leukoreduced; RBC, red blood cell product; PLT, platelet product.
Table reports units of product (ie, one unit from one donor). For pooled platelets, one “unit” represents pool of 6 random concentrates. CMV status of pool is positive if one unit in pool is positive or unknown.
