Specimen Collection and Processing for Coagulation Specimens



Collection Instructions

Specimen:Blood
Optimal Volume:2.7 mL (in 3 mL tube) - filled to fill line on the tube
Minimum\Peds Volume:1.8 mL (in 2 mL tube) - filled to fill line on the tube
Collection Instructions:If the patient's hematocrit is >55%, contact laboratory to obtain a special tube.
After Care:If the patient has a coagulation abnormality, apply direct pressure to the puncture site for 10 minutes; apply a pressure dressing. Instruct the patient to leave the bandage on for 12 hours.
Causes for Rejection:Underfilled tubes; clotted specimen; refrigerated specimen. Overfilled tubes.


Processing and Shipping

Specimen Processing:Store whole blood at room temperature up to 24 hours or process platelet poor plasma. See Associated Link for additional processing instructions.
