A feathered edge usually characterizes a good blood film. Use: EDTA whole blood. Automated enumeration of immature granulocytes. Turn the centrifuge off, if not an automatic turn off, and allow it to come to a complete stop. If the patient's hematocrit exceeds 55%, the volume of citrate in the collection tube must be adjusted. Hemolysis occurs when the thin protective membrane that encases the fragile red cells is ruptured, allowing hemoglobin to escape into the plasma. Testing schedules may vary. At some patient service centers, Labcorp provides biometric screening, which includes height, weight, blood pressure, waist circumference, body mass index (BMI), and blood draw for wellness screening. Plasma is obtained from blood that has been mixed with an anticoagulant in the collection tube and has, therefore, not clotted. 6.
