CryovCheck™ Factor XII Deficient Plasma is recommended for use as a substrate in clot-based Factor XII assays using the activated partial thromboplastin time (APTT) assay.
Cryo✓Check™ Factor XII Deficient Plasma is frozen human plasma deficient in the Factor XII coagulation factor. It is prepared from citrated pooled normal human plasma which has been depleted of Factor XII by immunoadsorption. Activity levels of Factor XII are assayed at less than 1% normal levels while all other coagulation factors are greater than 50%.
Acceptance Criteria and Study Details for Cryo✓Check™ Factor XII Deficient Plasma

§ 864.7290 Factor deficiency test.
(a)
Identification. A factor deficiency test is a device used to diagnose specific coagulation defects, to monitor certain types of therapy, to detect coagulation inhibitors, and to detect a carrier state (a person carrying both a recessive gene for a coagulation factor deficiency such as hemophilia and the corresponding normal gene).(b)
Classification. Class II (performance standards).
