Achieve Confidence in your APTT Testing Results

Convenient kit improves assay performance

If you are running the one-stage activated partial thromboplastin time (APTT) method to help manage your haemophilia A patients, the new CRYOcheck™ Factor VIII deficient plasma with Von Willebrand Factor (VWF), from Precision Biologic, could improve your assay performance.
 
Available from Alpha Laboratories, it is currently the only commercially available manufactured Factor VIII deficient plasma that compares to using congenital Factor VIII deficient plasma. Since access to congenital FVIII deficient plasma is limited and has high donor variability and small pool sizes, this newly available product provides enhanced convenience and increased confidence in testing results.
 
The CRYOcheck™ Factor VIII deficient plasma with VWF is manufactured from platelet-poor plasma. It has been immunodepleted of FVIII and then purified VWF is reintroduced to normal levels. FVIII has been assayed at less than 1% normal antigen and activity levels, with VWF antigen and activity levels at >50%. The plasma is buffered and frozen, with the frozen format eliminating reconstitution errors and a 24-hour stability once thawed if refrigerated at 2°C-8°C in the original capped vial.
 
Precision Biologic provides a full range of factor deficient plasmas, plus the Chromogenic Factor VIII and Factor VIII Inhibitor diagnostic kits.
