What is it?

The 4Kscore Test is an in vitro diagnostic test system designed to evaluate a patient’s likelihood of aggressive prostate cancer by measuring concentrations of four proteins (total PSA, free PSA, intact PSA, and kallikrein 2) in a patient’s blood sample, along with a patient’s age, previous biopsy, and digital rectal exam results.

How does it work?

A patient’s blood sample is sent to a specific laboratory for testing. The blood is analyzed for concentrations of these four proteins in serum or K2EDTA plasma. The 4Ksore Test result is a number calculated by an algorithm based on values using results of these four proteins in combination with a patient’s age, previous biopsy, and digital rectal exam (DRE). A medical professional reviews the results and sends a report to the patient’s doctor. The doctor uses this information to help manage the care of patients with an abnormal age-specific total PSA (tPSA) and/or abnormal DRE.

When is it used?

The 4Kscore Test is used to test patients, ages 45 years and above, with an abnormal age-specific tPSA and/or abnormal DRE finding.

What will it accomplish?

Test results from the 4Kscore Test are used to help doctors determine if a patient has an aggressive prostate cancer.

When should it not be used?

The 4Kscore Test should not be used in patients who:

Have a previous diagnosis of prostate cancer
Had a digital rectal exam (DRE) performed within 96 hours before blood draw
Have used 5-alpha reductase inhibitors within the previous 6 months
Had prostate procedures within the previous 6 months
