PSP94 is one of the three major proteins secreted in the seminal fluid, together with PSA and Prostatic Acid Phosphatase (PAP). PSP94-based test kits measure the amount of free PSP94, bound PSP94 and PSP94 binding protein present in the blood, the relative ratios of which are believed to have utility in prostate cancer prognosis, diagnosis and monitoring. These test kits differentiate between patients with prostate cancer and patients with benign conditions among patients who underwent a biopsy for prostate cancer. The PSP94-based test kits have the potential to significantly reduce the number of first and repeat prostate biopsies thus reducing the associated cost, morbidity and infection risk. Recent studies also indicate that the PSP94-based test kits were able to predict patients suffering from a more aggressive disease. PSP94 was found to be a strong predictor of relapse post- radiotherapy as well as following radical prostatectomy.
