CBC (includes Differential and Platelets)
WBC, RBC, Hemoglobin, Hematocrit, MCV, MCH, MCHC, RDW, Platelet Count, MPV and Differential (Absolute and Percent - Neutrophils, Lymphocytes, Monocytes, Eosinophils, and Basophils)
If abnormal cells are noted on a manual review of the peripheral blood smear or if the automated differential information meets specific criteria, a full manual differential will be performed.
Whole blood from a full EDTA (lavender-top) tube
Microtainer 0.5 mL
1 mL whole blood EDTA (lavender-top) tube
Maintain specimen at room temperature. Do not refrigerate. If multiple draw, collect EDTA (lavender-top) tube last. Traumatic draw can introduce thromboplastin and trap WBC and platelets. Refrigeration can precipitate fibrin and trap WBC and platelets.
EDTA (lavender-top) tube
Room temperature: 48 hours
Refrigerated: 48 hours (may cause platelet clumping)
Hemolysis • Clotted • Received frozen
