Twenty-five years ago, Precision BioLogic launched its first CRYOcheck™ product: a normal control for PTs and APTTs that could also be used as an alternative to in-house collected pools of normal plasma.
The benefits of frozen quickly caught on and CRYOcheck grew from a single product to an integrated line of frozen controls, calibrators, reagents and diagnostic kits that have become synonymous with quality in labs around the globe.
Why frozen?
✓ No reconstitution errors
✓ Long outdating reduces validation frequency
✓ Less manual preparation saves time
