The Biotime tPSA Rapid Quantitative Test measures total Prostate-Specific Antigen (tPSA) in human serum samples using a fluorescence immunoassay technique. PSA is a protein secreted by both normal and malignant prostate cells, and its concentration in blood is an essential indicator for assessing prostate cancer, benign prostatic hyperplasia (BPH), and prostatitis.

This rapid test offers clinicians a dependable method for early detection, risk assessment, and treatment monitoring of prostate-related conditions. The combination of speed, accuracy, and simplicity makes it suitable for use in urology departments, oncology centers, and clinical laboratories.
