A nurse or medical technician will use a needle to draw blood from a vein, most likely in your arm. The blood sample is then analyzed in the lab to measure your PSA level.
Prostate-specific antigen (PSA) is a protein produced by normal prostate cells. This enzyme participates in the dissolution of the seminal fluid coagulum and plays an important role in fertility. The highest amounts of PSA are found in the seminal fluid; some PSA escapes the prostate and can be found in the serum.
A prostate-specific antigen (PSA) test measures the level of PSA in your blood. The prostate is a small gland that is part of a man's reproductive system. It is located below the bladder and makes a fluid that is part of semen. PSA is a substance made by the prostate. Men normally have low PSA levels in their blood.
Prostate-specific antigen (PSA) is a protein made by cells in the prostate gland (both normal cells and cancer cells). PSA is mostly found in semen, but a small amount is also found in blood. The PSA level in blood is measured in units called nanograms per milliliter (ng/mL).
PSA is an enzyme normally produced by the glandular tissue of the prostate. It is produced at detectable levels only by prostate tissue. PSA is normally secreted outside of the body in urine or semen.
Prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3), P-30 antigen, is a glycoprotein enzyme encoded in humans by the KLK3 gene. PSA is a member of the kallikrein-related peptidase family and is secreted by the epithelial cells of the prostate gland.
The PSA test is a blood test that checks the levels of a protein (prostate-specific antigen) made by a man's prostate. This test can be used to find cancer in the prostate gland at an early stage. A high PSA level can be a sign of cancer, but can also be a sign of other things, like an enlarged prostate.
High PSA? Here are 7 common things that can affect your PSA levelAge. Older men's normal PSA levels run a little higher than those of younger men. ... Prostate size. ... Prostatitis. ... Benign prostatic hyperplasia (BPH) ... Urinary tract infection or irritation. ... Prostate stimulation. ... Medications.
Although it provides early diagnosis, the PSA blood test has a low specificity (high false positives) with about 75 per cent of all PSA positive results ending up with negative biopsies that do not find cancer.
