•Leukocyte aggregation may report a falsely decreased WBC.
•Falsely increased WBCs may be caused by PLT clumps, cryoprotein,cryoglobulin, fibrin, and giant platelets.
•Samples stored at room temperature more than 4 hours may exhibit an increase in MCV. RDW-SD, HCT, and MPV, and decrease in MCHC and total WBC.
•Lipemia, icterus, cold agglutinins, RBC fragments, lyse resistant RBCs, giant platelets, abnormal plasma proteins, clumped platelets, and fibrin strands may affect test results.
