Test Code COM Complement, Total, Serum

Important Note

GEL/SST SPECIMENS NOT ACCEPTED!

 

Per Mayo, the most important thing about processing Complement Testing is keep the specimen COLD (< 10⁰C)!  Ice packs can be used to collect, and the blood should clot on ice or refrigerated. Ice packs warm up quickly so you must monitor and change the ice packs when they warm up if using ice packs to clot. Once the blood has clotted, it should be spun down and FROZEN IMMEDIATELY.
