From Heather DeVries, Indiana University Health, a follow-up to Dr. King's April 26 pseudothrombocytopenia entry: Hi George, I recently read an article by Drs. Adcock Funk, Lippi, and Favaloro about quality standards in coagulation testing.

From Lissette, UCLA: We requested our hematology specimens to be sent with a warm pack for CBC/DIFF. Is it recommended to keep the sodium citrate tubes for coagulation testing on warm packs as well for patients with cold agglutinin? Is there a recommended method to workup these specimens for coagulation testing?

Hemostasis laboratories prepare platelet poor plasma (PPP ), plasma with a platelet count below 10,000/uL for clot-based procedures. The CAP doesn't specify how the laboratory validates their specimens to ensure they are PPP. Please summarize your protocol for our participants. Thank you.

From George: Long ago at a Temple University-sponsored meeting in Philadelphia, Dr. Dorothy Adcock provided data showing it was unnecessary to collect a "discard" tube ahead of a blue-closure hemostasis specimen.
