John A. Koepke, Alan L. Landay

Research output: Contribution to journalArticlepeer-review


A critique of leukocyte counting using automated hematology instruments is presented. Important preanalytical variables include the anticoagulant and specimen assay delays. The precision of counts is directly related to the number of leukocytes counted. Criteria for the selection of an acceptable hematology laboratory for lymphocyte counts for CD4 determinations are presented.
