title: Recognition and prevention of two cases of erroneous haemocytometry counts due to platelet and white blood cell aggregation. The use of acid citrate dextrose as an auxiliary anticoagulant.
abstract: Two cases of anticoagulant-induced platelet-white blood cell aggregation are described, which resulted in erroneous haemocytometry counts. Aggregation was avoided by the use of acid citrate dextrose (ACD) as an auxiliary anticoagulant, thus enabling quantification of platelets and white blood cells.
