What is PSA?
PSA is used as a screening marker for prostate health. Elevated PSA can indicate an enlarged prostate, inflammation (prostatitis), or in some cases prostate disease. Interpretation depends on age, trend, and clinical context. A single measurement is rarely conclusive—trends and possible follow-up testing provide the most reliable picture. This test is only relevant for men.
Why is PSA relevant?
PSA is a protein produced by the prostate and is used as a screening marker for prostate health in men. Elevated values can fit several situations: an enlarged prostate, inflammation (prostatitis), or in some cases prostate disease. PSA is a directional indicator, not a diagnosis on its own — a single abnormal value rarely warrants immediate concern and is usually re-tested in the context of symptoms and other factors.
How to read PSA in context
Always read PSA together with age, prostate size, recent activities (cycling, ejaculation, or a prostate examination can temporarily lift the value), and the trend across multiple measurements. A persistent upward trend is usually more informative than a single value. With doubt or strongly elevated readings, follow-up assessment by a clinician is the next step; this test is only relevant for men.
