Why Use FinalFix?

Many commercial labs allow shipment of biopsies in aqueous-based fixatives. Up to 40% of these biopsies freeze in shipment, resulting in freezing damage and substantial loss of nerve fibers (see Image B).

Artifactual loss of nerve fibers may lead to a false diagnosis of peripheral neuropathy.

FinalFix is a proprietary formula specifically designed to eliminate damage during shipment (see Image C).
