Biopsy Kits

Know Error Kit

Surgical biopsy kits are available at no cost for practices utilizing the know error® system. All of our professional kits include the components necessary for DNA Specimen Provenance Assay (DSPA) testing and the surgical biopsy process—kit components include a unique bar code system, biopsy collection jars*, buccal swabs to collect the DNA reference sample, transport vials for malignant tissues, return mailers and a patient educational piece explaining the benefits of DNA testing (DSPA). The Know Error DNA test (DSPA) used as part of the know error system is designed to confirm that the DNA of the tissue(s) matches the DNA of the reference sample identified as belonging to the patient and to rule out specimen contamination.

Our most common kits are for prostate and breast biopsies and more information is available on our Know Error website.
