What is normal PSA by age?

The normal PSA levels for men, who do not have prostate cancer or any other prostate-related conditions, vary with age — generally, the older the age, the higher the normal range of PSA. This normal PSA range is not a single value but rather spans from a lower to an upper limit. Additionally, these ranges are not specific to an individual age but are grouped by decade. For example, the normal PSA range for men aged 40-49 years is 0 to 2.5 ng/mL, for those 50-59 years old it is 0 to 3.5 ng/mL, for 60-69 years old the range is 0 to 4.5 ng/mL, and for men aged 70-79 years, it's 0 to 6.5 ng/mL.

The term 'ng/mL' in the context of normal PSA levels refers to 'nanograms per milliliter' in serum or plasma, with serum being the more commonly used medium. A nanogram is one thousand-millionth of a gram.

An increase in PSA levels above the upper limit of the normal range for one's age group does not automatically indicate prostate cancer. Rather, it signals that there may be an issue with the prostate gland that warrants examination by a doctor. Conditions such as benign prostatic hyperplasia (an enlarged prostate) and prostatitis (inflammation of the prostate) can cause the PSA to rise above the normal range for your age group.
