Professional Prostate Biopsy Kits

Excluding cancers of the skin, prostate cancer is the most common cancer in American men–and also one of the most deadly. It is currently the second leading cause of cancer deaths, second only to lung cancer.¹

Approximately 650,000 prostate biopsies are performed annually in the U.S. each year², about 30% of which will result in a cancer diagnosis. Given the complex nature of the biopsy evaluation process executed at this large of a scale, preventing diagnostic mistakes due to Specimen Provenance Complications (SPCs) is crucial to facilitate proper treatment and optimal patient outcomes. The patented know error^®system utilizes DSPA testing, a buccal swab-to-biopsy tissue comparison, to rule out the possibility of specimen contamination errors and confirm the cancerous tissue(s) belongs exclusively to the patient being evaluated.

Professional kits contain the components for confirming the assigned patient and ruling out contamination errors in the diagnostic process. Use your curser to pause (hover over) and advance the graphics (click the arrows).

Know Error Kits

The know error^® system enhances diagnostic accuracy by ruling out contamination and switching errors that can occur during the biopsy process.

Prostate Biopsy Kit

All Know Error prostate kits contain the components necessary for DNA testing and biopsy collection.

Patient Information Card

The Patient Information Card provides the patient with answers to common questions about DNA testing.

DNA Reference Swabs

Cheek swabs are for collecting the patient’s DNA reference sample before the biopsy procedure.

Biopsy Collection Vials

Each formalin-filled collection vial is specifically bar coded for use with this kit.

Biopsy Collection

The 16 vial insert, labeled for left and right biopsy locations, and orange Part D box are sent to pathology.

Pathology Components

The Part D box contains vials for sending the tissue scrolls taken from positive for cancer biopsy specimens to Strand Diagnostics for DNA analysis.

The know error^® system for prostate biopsies was launched in the spring of 2009 and has gained widespread acceptance among leading urology practices throughout the United States. Hundreds of physicians have implemented this system as part of their standard of care to enhance diagnostic accuracy and safety for prostate biopsy patients.
