Although the term ‘normal PSA level’ is often used, there isn’t a single number for a normal PSA level. There are a few reasons for this:
- The older you are, the higher your PSA level is likely to be, whether or not you have prostate cancer.
- PSA levels vary with the size of your prostate gland (this differs from man to man and the gland gets bigger with age).
- Different laboratories use different methods to measure PSA levels.
- Specialists have different opinions on what’s ‘normal’.
It’s best to check with your specialist what they think the normal level should be for you. The numbers given here are only a guide and are based on age:
- For men in their 50s, a PSA level of up to 3 nanograms per millilitre of blood (3ng/ml) is considered normal.
- For men in their 60s, a PSA level of up to 4ng/ml is considered normal.
- For men aged 70 and over, a PSA level of up to 5ng/ml is considered normal.
