High PSA Levels: Understanding Elevated PSA Test Results

Many non-cancerous conditions can raise PSA levels:

  • Enlarged prostate (BPH)
  • Prostate infection
  • Recent ejaculation
  • Vigorous exercise

Free PSA Test: Understanding PSA Antigen Levels

If your PSA is between 4-10 ng/mL, your doctor may order a free PSA test. This measures the percentage of PSA that's not bound to proteins.

Free PSA Percentage Guide:

  • • Above 25%: Lower risk of cancer
  • • 10-25%: Moderate risk
  • • Below 10%: Higher risk, further testing recommended

PSA blood test vs urine test: What type is PSA screening?

PSA is a blood test. A small sample is taken from a vein in your arm.

PSA screening frequency: How often for PSA test by age?

Men with normal PSA may retest every 2-4 years. Those with elevated levels may need annual testing. Your doctor will recommend the best schedule for you.

What is PSA Test? Prostate Specific Antigen Explained

Understanding prostate specific antigen, PSA blood screening, and PSA antigen test

PSA (Prostate-Specific Antigen) is a protein produced by prostate cells. The PSA blood test measures prostate specific ag levels to screen for prostate health. Understanding normal PSA values and PSA count is essential for men's health screening.

Key Facts About PSA:

  • PSA is measured in nanograms per milliliter (ng/mL) of blood
  • Levels naturally increase with age
  • Not specific to cancer - many conditions can raise PSA
  • Used for screening, not diagnosis

Why PSA Screening Matters: PSA Test for Men

PSA testing can help detect prostate problems early, including cancer, when treatment is most effective. However, it's important to understand that PSA testing is just one tool in prostate health screening.
