First Choice Bio’s Off-the-Clot Serum is obtained by allowing whole blood collected without an anticoagulant to naturally coagulate. The Serum, or fluid portion, is then collected and the Fibrin Clot is removed.

Whole Blood Serum is collected from healthy donors by venipuncture and according IRB approved procedures from fully consented donors that tested negative for HIV, HBV and HCV .
