PSA levels can be detected in the blood, urine, or semen. Blood PSA testing is used as a screening test for prostate cancer. Prostate-specific antigen (PSA) levels by age remain the same across most populations. A PSA level above 4.0 ng/mL in any age group must be investigated.
Age 60 or older: should be at or below 4.0 mg/mL. Age 59 or younger: should be at or below 2.5 mg/mL. The average PSA for men in the younger group is <1.0 mg/mL. Why are my PSA levels elevated? Your PSA levels could be elevated for many reasons.
While the general guidelines recommend starting at age 55, you may need PSA screening between the ages of 40 and 54 if you: Have at least one first-degree relative (such as your father or brother) who has had prostate cancer. Have at least two extended family members who have had prostate cancer.
Eleven per cent of men (n=155) had a PSA level of ≥ 6.5 ng/mL (the suggested cut-off for further investigation for men aged 70 or over, from an American study), increasing from 7.5% of men aged 70–74 years to 31.4% of men aged ≥ 90 years.
The task force recommends that men ages 55 to 69 make a shared decision with their doctors regarding routine prostate cancer screening, which usually means periodic blood tests for prostate-specific antigen (PSA). The task force advises men to stop screening once they reach age 70.
A healthcare provider looks at two factors that relate to your PSA to determine your prostate cancer risk: Your PSA level. A higher PSA level means you have a higher risk of prostate cancer. A continuous rise. PSA levels that continue to rise after two or more tests may indicate prostate cancer.
The PSA test can detect high levels of PSA that may indicate the presence of prostate cancer. However, many other conditions, such as an enlarged or inflamed prostate, also can increase PSA levels. Therefore, determining what a high PSA score means can be complicated.
PSA screening may help you detect prostate cancer early. Some prostate cancers are slow growing and never spread beyond the prostate gland. Cancer is easier to treat and is more likely to be cured if it's diagnosed in the early stages of the disease. Not all prostate cancers need treatment.
There's no one PSA level that's considered normal. In general, PSA levels are higher in older people than in younger people, even in those who don't have prostate cancer or other prostate...
The PSA test measures the level of PSA in the blood. For this test, a blood sample is sent to a laboratory for analysis. The results are usually reported as nanograms of PSA per milliliter (ng/mL) of blood.
