FIX is a vitamin K dependent glycoprotein synthesized by the liver.
The FIX can be activated in FIX in FIXa by the FXIa or by FVIIa in the presence of phospholipids and calcium.
A person who is deficient in FIX has hemophilia B.
The CRYOcheck™ Chromogenic Factor IX is used to identify FIX deficiency and helps in the management of hemophilia B in people aged 2 years and older
