The PSA (Prostate-Specific Antigen) blood test is one of the most important tools in modern urology for the prevention and early detection of prostate pathologies. It consists of a simple blood draw that measures the concentration of this protein produced by the prostate gland.
Generally, it is recommended to take the PSA test once a year starting at age 50 in the general male population. However, in men with a family history of prostate cancer or with urinary symptoms, specialists advise advancing the first screening to age 40 or 45.
What is PSA and what is it for?
Prostate-Specific Antigen is a substance naturally produced by the prostate to liquefy semen. A small amount of this protein passes into the blood, making it possible to evaluate prostate health through a laboratory analysis.
Why is the PSA test performed?
- Screening and prevention: allows for the early detection of prostate cancer in its initial stages, before any symptoms appear.
- Identification of benign pathologies: helps diagnose Benign Prostatic Hyperplasia (non-cancerous enlargement of the gland) or inflammatory/infectious processes (prostatitis).
- Medical follow-up: it is key to monitoring patients who are already receiving urological treatment.
When is it recommended to take the PSA test?
The indication for the test varies depending on age, genetics, and the presence of urinary discomfort:
A. From age 50 (General population)
Even if there are no symptoms or family history, every man over 50 should include the PSA analysis in their annual urological check-up or blood test.
B. From age 40-45 (Risk factors)
It is a priority to take the test at earlier ages if you meet any of these criteria:
- Direct family history: having a father or brother who has suffered from prostate cancer increases the risk.
- Known genetic predisposition.
C. Presence of urinary symptoms
Regardless of your age, you should request a medical evaluation and a PSA test if you experience:
- Difficulty or straining to start urinating.
- Frequent need to urinate, especially at night (nocturia).
- Weak, interrupted urine stream or dribbling at the end.
- Feeling that the bladder is not completely empty.
- Presence of blood in the urine or semen.
Complementary diagnostic tests for prostate health
The PSA value in the blood is an orientation signal that must be evaluated by a urologist within a comprehensive consultation. To obtain a definitive diagnosis with maximum precision, at CreuBlanca we combine blood tests with the latest generation diagnostic technology:
- Prostate and renovesico-prostatic ultrasound: allows real-time evaluation of the exact size and structure of the prostate gland.
- Multiparametric Prostate Magnetic Resonance Imaging (3 Tesla MRI): is the most advanced diagnostic imaging technology available. It offers exceptional resolution of prostate tissues without the need for radiation, allowing for the precise delimitation of any suspicious lesions.
When should you see a urologist?
Obtaining a PSA result in a routine blood test always requires the interpretation of a specialist. If you have taken the test and your levels are altered, or if you simply have doubts about your results, you can consult our detailed guide on what to do if my PSA is high to understand the next steps.
Remember that a PSA value above the average is not automatically synonymous with cancer; in most cases, it is due to benign conditions such as hyperplasia or an infection (prostatitis). Going to a consultation with a urologist is the safest step to clear up any doubts and receive the appropriate indication.
