Off-the-Clot Human Serum – True Human Quality

TRINA's off-the-clot human serum, often called "true human serum," is produced by allowing whole blood to naturally coagulate before separating the serum. This approach eliminates the need for anticoagulants or preservatives, resulting in a premium basematrix ideal for IVD controls and calibrators. Unlike artificially defibrinated plasma, this serum is free from hemolysis, lipemia, and icteric properties, ensuring reliable, interference-free assay performance.

Collected from licensed donation centers worldwide, each unit typically ranges from 255 mL to 325 mL. Detailed donor information, including age, gender, and collection date, is available upon request. Every unit undergoes extensive testing with FDA-approved methods, ensuring it is non-reactive for HBsAg, anti-HIV 1/2, anti-HCV, syphilis, HIV-1 RNA, HCV RNA, and HBV DNA.
