Human serum 'off-the-clot' is processed from human blood that has been coagulation-induced. It is collected from volunteer donors.

Mainly sourced from France, Germany, Canada or USA, each batch is rigorously controlled and screened for Hepatitis B (HBS), Hepatitis C (HCV) and HIV Types 1 and 2 (HIV 1/2).

Important note: Products of human origin should be considered potentially infectious and handled accordingly.
