What Is a PSA Blood Test?
A PSA (Prostate-Specific Antigen) blood test measures the level of PSA protein in your blood. PSA is produced exclusively by the prostate gland, and elevated levels can be an early indicator of prostate cancer, benign prostatic hyperplasia (BPH), or prostate infection.
Prostate cancer is the most common cancer among American men — 1 in 8 will be diagnosed in their lifetime. A PSA test is the primary screening tool for early detection, when treatment options are most effective and survival rates are highest. Ordering through Personalabs means you can get screened proactively without waiting for a doctor’s appointment.
What Does the PSA Blood Test Measure?
This test measures total PSA and free PSA in your blood. PSA is a protein produced only by prostate cells. When the prostate is healthy, PSA levels are low. When the prostate is affected by cancer, inflammation, infection, or benign enlargement (BPH), PSA levels typically rise.
The free:total PSA ratio is particularly useful when total PSA falls in the borderline range of 4.0–10.0 ng/mL — a higher percentage of free PSA generally suggests a lower likelihood of cancer, while a lower percentage raises concern and may warrant a biopsy.
PSA Blood Test Normal Ranges
| PSA Level (ng/mL) | General Interpretation |
|---|---|
| Below 4.0 | Generally considered normal |
| 4.0 – 10.0 | Borderline — further evaluation often recommended |
| Above 10.0 | Elevated — follow-up with urologist strongly advised |
Important: PSA levels are not diagnostic on their own. Elevated PSA can be caused by prostate cancer, BPH (benign enlargement), prostatitis (infection/inflammation), recent ejaculation, or recent prostate exam. Results should always be reviewed with a healthcare provider.
Age-adjusted reference ranges are also used by many providers, since PSA naturally rises with age:
| Age | Typical PSA Reference Range |
|---|---|
| 40–49 | 0–2.5 ng/mL |
| 50–59 | 0–3.5 ng/mL |
| 60–69 | 0–4.5 ng/mL |
| 70+ | 0–6.5 ng/mL |
Who Should Get a PSA Blood Test?
Men age 50 and older should discuss annual PSA screening with their doctor as part of routine preventive care.
Men at higher risk should start earlier — at age 40 or 45:
- African American men (higher incidence and earlier onset of prostate cancer)
- Men with a first-degree relative (father or brother) diagnosed with prostate cancer before age 65
- Men with known BRCA1 or BRCA2 gene mutations
Also recommended if you experience:
- Frequent or urgent urination
- Difficulty starting or stopping urination
- Weak urine stream
- Blood in urine or semen
- Pelvic or lower back discomfort
PSA Blood Test Preparation
No fasting required. However, follow these important guidelines for accurate results:
- Avoid ejaculation for 24 hours before your blood draw — ejaculation can temporarily elevate PSA levels and affect accuracy
- Get your blood drawn before any digital rectal exam (DRE) or prostate biopsy — these procedures can artificially raise PSA
- If you are taking finasteride (Proscar, Propecia) or dutasteride (Avodart), tell your provider — these medications lower PSA levels and your result may need to be interpreted differently

Frequently Asked Questions: PSA Blood Test
What is a normal PSA level by age?
PSA levels naturally increase with age as the prostate grows. General age-specific guidelines: Under 50 — below 2.5 ng/mL is normal. Ages 50–59 — below 3.5 ng/mL. Ages 60–69 — below 4.5 ng/mL. Ages 70+ — below 6.5 ng/mL. However individual baseline matters more than the absolute number. A rising PSA — even within normal range — is more concerning than a stable elevated PSA.
What can cause a high PSA besides cancer?
Many non-cancerous conditions cause PSA elevation. Benign prostatic hyperplasia (BPH) — prostate enlargement — is the most common cause. Prostatitis — prostate inflammation or infection — can significantly elevate PSA. Recent ejaculation within 24 hours, a digital rectal exam, cycling, or prostate biopsy can all temporarily raise PSA. This is why guidelines specify avoiding ejaculation for 24 hours before testing.
At what age should men start PSA testing?
Most guidelines recommend PSA screening discussions starting at age 50 for average-risk men. Men at higher risk should start at age 40 to 45 — this includes African American men and men with a father or brother diagnosed with prostate cancer before age 65. Early baseline testing at 40 is valuable because it establishes your personal normal range for future comparison.
Do I need to fast before a PSA test?
No fasting is required for a PSA test. However avoid ejaculation for 24 hours before your blood draw — ejaculation temporarily elevates PSA and can affect accuracy. Also get your blood drawn before any digital rectal exam, prostate massage, or prostate biopsy as these procedures raise PSA significantly.
Can I order a PSA test without a doctor?
Yes. Personalabs provides the physician-approved lab order with your purchase. Order online, visit any Labcorp patient service center near you, and get results in your secure private account within 24 to 48 hours. No referral required. HSA and FSA eligible.
