What PSA - Total (Prostate Specific Antigen) measures
A protein made by the prostate, used to screen for prostate disease including enlargement, infection and cancer.
PSA - Total (Prostate Specific Antigen) normal range by age and gender
What a high PSA - Total (Prostate Specific Antigen) means, and common causes
PSA is above range. It is raised far more often by benign prostate enlargement and infection than by cancer, so a high value starts a conversation, not a diagnosis.
Common causes: Benign prostatic hyperplasia, prostatitis, urinary infection, recent catheterisation or prostate examination, cycling, ejaculation within 48 hours, and prostate cancer.
What a low PSA - Total (Prostate Specific Antigen) means, and common causes
A low PSA is the expected normal result.
Common causes: Not applicable, though finasteride and dutasteride roughly halve PSA and the result must be interpreted with that in mind.
