Due to the small volume and negative pressure inside the tube, allow sufficient time for complete blood collection. Wait patiently until blood stops flowing into the tube. Then thoroughly mix the anticoagulant and additive by turning the tube upside down 6-8 times. Inappropriate mixing may cause hemolysis, coagulation, or blood bubbles that affect test results.
