## Indications for use
Deficiencies in coagulation factors may have congenital or acquired etiologies and can compromise in vivo hemostasis. Prekallikrein or Fletcher factor, is a single chain polypeptide with a molecular weight of 85,000 and is necessary for normal coagulation of the “intrinsic coagulation pathway”. Prekallikrein deficiency is commonly diagnosed in vitro through the use of the activated partial thromboplastin time (APTT), an intrinsic pathway screening assay and confirmed with a quantitative prekallikrein assay which is an APTT-based clotting assay. Cryov'Check™ Prekallikrein Deficient Plasma is human plasma deficient in the prekallikrein coagulation protein. It is recommended for use as a substrate in clot-based prekallikrein assays using the activated partial thromboplastin time (APTT).
