PSA: request for prostate cancer screening and raised PSA

Urology and andrology · Abnormal laboratory result · updated 2026-10-30

BioMG follows French guidelines. Adapt it to the guidelines and the tests available where you practise.

Frequency: 62% of men aged 50 to 69 with no known prostate cancer had at least one PSA test between 2012 and 2014 ^[1]

Asymptomatic man considering screening (individual early detection)

Only after information on the benefits, limits and risks (overdiagnosis, biopsies, treatments) and a shared decision.

Total PSA (away from ejaculation, a urological procedure and any urinary tract infection)
Combine with a digital rectal examination.

Routine screening, without prior information: no health authority or learned society recommends it, in France or abroad; the HAS does not justify it either in men at risk ^[1].
Free PSA (free:total ratio) as first-line: not recommended ^[1,2]; its reimbursement is limited to total PSA > 4 ng/mL, to distinguish benign hyperplasia from localised cancer ^[3].
PSA in a man without symptoms whose life expectancy is under 10-15 years: he will not benefit from it ^[1,4].

Repeat total PSA
Urine microscopy and cultureif neededUrinary signs or suspected infection: a urinary tract infection, especially febrile, can raise PSA very markedly (sometimes > 100 ng/mL) and normalisation can take up to a year ^[4]. During a urinary tract infection in a man, PSA is not recommended ^[13]. Since 2026, the SPILF considers PSA not routine after a male urinary tract infection and, if necessary, has it measured at least 3 months after the infection ^[12,14].
Digital rectal examination. Confirmed PSA or suspicious rectal examination: refer to the urologist (prostate MRI before any biopsy).

Detailed explanation and international comparison (in French): read it in English (machine translation)

PSA during a urinary tract infection or prostatitis: not recommended for the diagnosis of the infection ^[12,13], and falsely raised, sometimes for months ^[4]; if useful, wait at least 3 months after the infection ^[12,14].
Biopsy or referral on a single moderately raised PSA (3 to 10 ng/mL) without recheck: a third of men differ by more than 1 ng/mL on the second measurement, and PSA falls back below 3 ng/mL in about one in five within 1 to 2 months ^[4].
Free PSA to decide alone on a biopsy: combined tests (PHI, 4K score) perform better than the free:total ratio, and MRI is the reference imaging test before biopsy ^[4,5]. In chronic kidney disease, the percentage of free PSA rises (reduced glomerular filtration) and can lead a cancer to be mistaken for benign hyperplasia: do not use it ^[15].
