The PSA test measures the total concentration of Prostate-Specific Antigen in your bloodstream. PSA is a protein produced by both normal and cancerous cells in the prostate gland, which sits just below a man’s bladder. While it is completely normal for small amounts of PSA to circulate in the blood, an elevated level serves as a primary, highly sensitive biological smoke alarm. Measuring PSA levels helps clinicians screen for structural changes within the prostate gland, assess underlying cellular stress, and detect early-onset prostate conditions long before physical symptoms appear. 🩺🛡️

When is this test performed and for which diseases? 🤔

• To Screen for Early Malignancies: This test is performed as part of routine annual wellness checks for men over 40 (or earlier if there is a family history) to screen for Prostate Cancer when it is most treatable. 🚨🔍

• To Investigate Urinary Difficulties: It is ordered when a patient experiences symptoms like a weak urinary stream, straining, or frequent nighttime urination to diagnose Benign Prostatic Hyperplasia (BPH) (non-cancerous prostate enlargement). 🚽🛑

• To Identify Pelvic Pain and Infection: This examination is performed when a patient presents with sudden painful urination or lower back pain to identify Prostatitis (acute or chronic inflammation of the prostate gland). 🧼🏥

• To Monitor Post-Therapy Efficacy: It is performed regularly for patients undergoing chemotherapy, radiation, or surgery for prostate conditions to track Cancer Recurrence or check if treatment is successful. 📊

Test Specifications: 📋

• Sample Type: Blood (Serum) 🩸

• Preparation: No fasting is required. However, to ensure accurate baseline measurements, you must strictly avoid sexual activity/ejaculation, heavy bicycling, or undergoing a digital rectal exam (DRE) for at least 48 hours before the blood draw, as these activities compress the prostate and cause false spikes. 🚴‍♂️❌☀️

• Reporting: High-precision quantitative tumor marker results are typically delivered within 24 hours. ⏱️
