Collection Information
Blue top tubes must be filled within 10% of the stated volume. A discard tube must be used if a citrate tube is to be drawn using a winged blood collection set. It is important to remove air from the blood collection set to ensure the proper blood volume is obtained in the coag tube.
If the patient has a known hematocrit >55%, please contact the coagulation lab for an adjusted collection tube before drawing the blood.
