Alternate Containers: Red (no gel) AND Blue Na Citrate, 3.2% - fill to fill line on tube
Collection Instructions:Testing requires BOTH serum and citrated plasma samples, as well as an automated platelet count. Collect 6 mL; 2.6 mL minimum in a red or gold (gel) or red (no gel) AND 2.7 mL (in 3 mL tube) in a Blue Na Citrate, 3.2% tube - fill to fill line on tube. If a platelet count has not been performed in the last 3 days, draw a purple (EDTA) tube and add to the existing order.
Causes for Rejection:Hemolyzed specimens. All required specimens not received. No platelet count received.
