Early detection of prostate cancer often begins with a PSA (Prostate Specific Antigen) test. While PSA is an effective initial prostate screening test, the result can be abnormal in a variety of benign (non-cancerous) conditions as well as in prostate cancer and lacks the specificity to distinguish between aggressive, potentially lethal prostate cancer and less serious cancer forms. As a result, many men are subjected to invasive procedures, including prostate biopsies, that could be avoided. Approximately 25% of biopsies performed after an abnormal PSA screening test detect aggressive prostate cancer. The majority of prostate biopsies find either no cancer or detect the low-grade, slow-growing forms of prostate cancer.1
The 4Kscore® Test is a follow-up blood test after an abnormal PSA and/or digital rectal exam (DRE) to assess your probability of finding aggressive prostate cancer, using four prostate-specific biomarkers and your clinical information.
The 4Kscore® Test result assesses your probability of aggressive prostate cancer if a biopsy were performed and has been shown to categorize long-term risk of cancer metastasis or of dying from prostate cancer.

The 4Kscore Test result provides you and your physician with your probability of finding high-grade, aggressive prostate cancer (Gleason 7 or higher) if a prostate biopsy were to be performed. The 4Kscore Test is FDA approved and has been validated in multiple U.S. and European studies in over 20,000 men. Evaluation of test results and management decisions should be made in consultation with your physician, based on your 4Kscore Test result and overall clinical history.
NOTE: Biotin concentrations up to 25 ng/mL in serum demonstrate a less than or equal to 10% change in measurement of The 4Kscore Test. Biotin concentrations greater than this may change The 4Kscore Test. results for patient samples.
Patients taking supplements containing biotin should discontinue usage for at least 3 days prior to 4Kscore testing.
A 4Kscore <5.0 is associated with decreased likelihood of a Gleason score ≥7 on biopsy.
Your physician will evaluate your 4Kscore result, along with your clinical information, and discuss options for next steps.
The 4Kscore® Test is a simple blood test and requires a test order from your physician. The blood can be drawn at your physician’s office or at a conveniently located Patient Service Center. Talk to your physician today to find out if The 4Kscore® Test is right for you.
If your physician does not have the ability to draw blood in their office, you can have your blood draw performed at a conveniently located Patient Service Center.
DISCUSS PROSTATE CANCER
Screening for prostate cancer is an individual decision for you to discuss with your physician. 1 in 9 men will be diagnosed with prostate cancer in their lifetime.2
MAKING A SHARED DECISION
Shared decision-making helps you and your loved ones make informed decisions. Discussing your medical history, clinical findings, and preferences with your physician will help you make a decision that is right for you.
This is a guide for screening and evaluation of aggressive prostate cancer and is not all inclusive of the probabilities, benefits, or complications for procedures and tests described. Please review this decision aid with your physician to determine the next steps in your care.
The 4Kscore® Test is an FDA approved follow-up blood test after an abnormal PSA and/or digital rectal exam (DRE) to assess the probability of finding aggressive prostate cancer if you were to have a prostate biopsy.
The 4Kscore® Test is FDA approved and has been validated in multiple U.S. and European studies in over 20,000 men. Disease management decisions should be made in consultation with your physician, based on your 4Kscore® Test result and overall clinical history.
The 4Kscore® Test result provides you and your physician with the probability of finding high-grade, aggressive prostate cancer (Gleason 7 or higher) if a prostate biopsy were to be performed and has been shown to categorize long-term probability of metastasis or death from prostate cancer. With this information, you and your physician can make better-informed healthcare decisions.
The 4Kscore® Test measures four prostate-specific biomarkers (Total PSA, Free PSA, Intact PSA, and human kallikrein 2 [hK2]), along with your clinical information (patient age, prior biopsy history, digital rectal exam result) using a complex algorithm to assess the probability of finding aggressive prostate cancer if you were to have a prostate biopsy.
The 4Kscore® Test does not diagnose prostate cancer. It is used after an abnormal PSA or DRE screening test to assist in the biopsy decision. The 4Kscore® Test assesses the probability of finding aggressive prostate cancer if you were to have a biopsy.
Yes. The 4Kscore® Test is approved by the FDA and included in current U.S., Canadian, and European prostate cancer early-detection guidelines. The four kallikrein biomarkers utilized in The 4Kscore® Test have been researched for over a decade by scientists at leading international cancer research centers. The accuracy and reliability of The 4Kscore® Test has been shown in clinical trials involving more than 20,000 men.
The 4Kscore® Test was validated in two large independent U.S.–based prospective studies, including a 2017 study performed at eight Veterans Health Administration facilities involving a majority of African American men. Over a dozen peer-reviewed articles have been published in leading medical journals on the clinical effectiveness of the 4Kscore® Test, and more than 200,000 4Kscore® Tests have been performed in the U.S.
Your physician should receive your 4Kscore® Test result within 2 to 3 working days from the time our laboratory receives your blood sample. Your physician will contact you to discuss your 4Kscore® Test result and options for next steps regarding your prostate health.
