Single Donor Human Serum Off The Clot Female - Single Donor Human Serum from Innovative Research is whole blood derived. The whole blood is collected from donors in an FDA-approved collection center. The blood is allowed to clot and is then processed into serum via centrifugation, and is frozen immediately after processing. Each unit is tested for the standard FDA-required viral markers, and found negative using FDA-approved methods. Innovative Research has a wide network of FDA-approved collection centers across the United States, which allows us to collect from nearly any donor type. We are able to accommodate demographic requests from a variety of genders, races, and ages. We are also able to work with custom collection requests and protocols.
