Deficient and inhibitor plasmas
Deficient plasmas
Deficient plasmas are used in single factor clotting assays. All coagulation factors except of the factor to be assayed are present in normal concentrations. We supply deficient plasmas for all coagulation factors, optionally in lyophilized or frozen form. You may find the deficient plasma for your individual needs here.
Our latest product in this field is a CE marked factor VIII deficient plasma with VWF. Unlike other artificial FVIII deficient plasmas, it does not contain any FVIII antigen that may bind FVIII inhibitors. Therefore, false low results in Nijmegen-Bethesda assays are avoided.
Inhibitor plasmas
Inhibitor plasmas serve as substitutes for patient plasmas with neutralizing antibodies to coagulation factors. They are ideally suited as positive controls for the respective inhibitor test. You may find an overview of our whole inhibitor plasma range here.
