Free/total prostate-specific antigen 0.28 is generally within the normal range, and regular checkups are sufficient.
Prostate-specific antigen is secreted by prostate epithelial cells and belongs to the kinase family of proteins. This substance exists in prostate fluid and semen, and the serum content is very low. It consists mainly of free prostate-specific antigen, and complex prostate-specific antigen, which together are called total prostate-specific antigen.
Under normal circumstances, the ratio of free/total prostate-specific antigen is around 10% to 30%, and the patient’s current index is 0.28, or 28%, which is still a normal level, so the patient should not be too nervous.
If the examination process, found that the free/total prostate-specific antigen ratio significantly lower than normal, or total prostate-specific antigen >10.0ng/ml, be alert to the existence of prostate disease, especially prostate cancer and other malignant lesions. At this time, it is necessary to analyze and confirm the diagnosis of the lesion through pathology and other examination programs.
