Many commercial labs allow shipment of biopsies in aqueous-based fixatives. Up to 40% of these biopsies freeze in shipment, resulting in freezing damage artifact and substantial loss of nerve fibers.
Losing nerve fibers may lead to a false diagnosis of peripheral neuropathy.
FinalFix is a proprietary formula specifically formulated to eliminate shipping damage during shipment.
