ATFirst™ PSA Rapid Test
A qualitative lateral flow cassette for prostate-specific antigen (PSA) in whole blood, serum or plasma, for use by healthcare professionals.
- Professional use
- Whole blood, serum or plasma
- 20 tests per kit
Intended use
The ATFirst™ PSA rapid test is a qualitative cassette for professional in vitro diagnostic use. It shows whether prostate-specific antigen in whole blood, serum or plasma is above the level defined in the insert, and supports clinical assessment alongside examination and laboratory findings.
PSA is a protein made by cells of the prostate gland, and a small amount is normally present in the blood of men. Levels can rise with prostate cancer, but also with benign enlargement of the prostate and with prostatitis. A raised PSA is therefore a reason for clinical follow-up, not a diagnosis. The cassette is part of the ATFirst™ rapid tests range distributed by First Diagnostic™ Corporation.

How the test works
PSA is measured here as an antigen. Antibody against PSA, bound to colored particles, attaches to PSA in the specimen; a second anti-PSA antibody at the test line traps the complex as it passes, as is usual for this test design. Some PSA cassettes carry a reference line in addition to the control line, so the insert must be followed for reading. More on the method: lateral flow tests.
What to confirm in the insert
- The PSA level at which the test line appears, and the form of PSA measured
- Specimen handling and sample volume
- Read window
- Storage conditions and shelf life
- Interpretation of line intensity, if the insert uses it
The insert supplied with each kit defines all of these and is available on request from sales@firstdiagnostic.com. See the product inserts page for inserts already published.
Limitations
- The test does not diagnose or rule out prostate cancer and is not a population screening tool.
- It reports no PSA value, so it cannot be used to follow PSA over time. Use a quantitative laboratory assay where a value is needed.
- Urinary infection, catheterization and prostate biopsy can raise PSA; some medicines for prostate enlargement lower it.
- A negative result does not exclude prostate disease.
