Description
fPSA Fast Test Kit (Immunofluorescence Assay)
The fPSA Fast Test Kit is a quantitative immunofluorescence assay designed for the detection of free prostate-specific antigen (fPSA) in human serum and plasma. It is primarily used to monitor disease progression or treatment response in patients with prostate conditions and must be used in conjunction with total PSA (tPSA) testing for improved clinical accuracy.
Key Advantages
- Rapid Results: Quantitative results in just 10 minutes
- Diagnostic Support: Used alongside tPSA to help distinguish prostate cancer from benign conditions
- Sample Compatibility: Suitable for serum and plasma testing
- Enhanced Specificity: fPSA/tPSA ratio improves accuracy in the 4–10 ng/mL “gray zone”
- Stable Storage: 4–30°C with 24-month shelf life
About fPSA
Free prostate-specific antigen (fPSA) is one form of PSA circulating in the blood. Lower fPSA levels are typically associated with prostate cancer, whereas higher levels are more often seen in benign prostatic hyperplasia (BPH). The fPSA/tPSA ratio is a critical tool in evaluating prostate health in men aged 50+ with borderline PSA levels. This test should not be used alone for cancer screening or early detection.
