Fragen und Antworten zu Freies PSA
What is the respective laboratory value?
Free PSA is the proportion of PSA that is not bound to proteins in the blood. The laboratory value measures the concentration of fPSA and is often set in relation to the total PSA to distinguish between benign and malignant prostate changes.
For whom is such a test to be considered?
A PSA test is recommended for: Men with an elevated total PSA level who require further evaluation Men with a family history of prostate cancer Monitoring of patients with a known prostate condition in whom prostate cancer needs to be excluded
What is it used for?
The test serves to assess the risk in men with elevated total PSA. A low fPSA ratio increases the likelihood that the cause is a malignant tumor.
What can be inferred from that?
A low fPSA value (in relation to total PSA) indicates a stronger likelihood of prostate cancer, while a higher proportion is more indicative of benign changes. Symptoms of a prostate condition may include: Frequent or painful urination Feeling of pressure in the pelvic area Blood in the urine
What is the ideal time for a test?
How the total PSA test should be performed, avoiding physical activity, manipulation of the prostate or sexual intercourse, in order not to distort the results.
Particularly interesting?
The fPSA value is usually only used in combination with the total PSA. A low fPSA ratio (<25%) may indicate a higher risk of prostate cancer. The test can help avoid unnecessary biopsies by improving the informative value of the total PSA value. However, we always recommend consulting a specialist in addition.
