From the Guidelines

It is recommended to avoid strenuous exercise for 2 days before a Prostate-Specific Antigen (PSA) blood test. According to the clinical practice guideline published in the BMJ in 2018 1, vigorous exercise, such as cycling, can result in false positive elevation of PSA levels. This is because strenuous physical activity can cause minor trauma to the prostate gland, leading to the release of more PSA into the bloodstream. To ensure accurate PSA test results, it is essential to avoid activities that may temporarily elevate PSA levels.

Key Considerations

  • Avoid vigorous exercise, such as cycling, for 2 days prior to PSA testing 1
  • Refrain from sexual activity, including ejaculation, for 2 days before the test 1
  • Inform your healthcare provider about any medications that may affect PSA levels, such as finasteride or dutasteride 1
  • Avoid prostate manipulation procedures, like digital rectal exams, before the test

Rationale

The guideline suggests that avoiding strenuous exercise and other activities that may elevate PSA levels can help ensure accurate test results 1. This is crucial in assessing prostate health and making informed decisions about further diagnostics or treatment. By taking these precautions, individuals can help their healthcare providers obtain reliable information about their prostate health.
