Chromogenic Factor IXDiagnostic Kits
CRYOcheck™ Chromogenic Factor IX is a chromogenic assay for the determination of factor IX activity in human plasma. It is intended to be used as an aid in the management of hemophilia B in individuals aged two years or older. With a limit of quantification of 0.5% FIX activity and a test range of 0–200% FIX using one standard curve*, CRYOcheck Chromogenic Factor IX provides unsurpassed assurance in results, especially in cases of patients with severe hemophilia B.
With the ability to store thawed reagents at 2 to 8°C for up to 48 hours, or refreeze for up to one month, labs of all sizes can meet their testing requirements while minimizing wastage.
- Convenient frozen format ready to use within minutes, no reconstitution errors
- Intended for use on automated coagulation analyzers
- Only one calibration curve used for entire measuring range of 0–200%*
- 24-hour on-board stability
- Excellent precision at low FIX activity
