What can be the PSA level when prostate adenoma and prostatitis?
When shown the PSA test for the man?
Usually the urologist recommends men to take the PSA test for prostatitis, or when you want to detect PSA levels in the adenoma. For this investigation, the laboratory assistant takes blood from a vein.
In the diagnosis of prostatitis and adenoma of a PSA is a subsidiary of laboratory examination method. For example, the value of PSA in BPH helps the doctor to recognize the beginning of the inflammatory process in the prostate gland, which is often characterized by the absence of any symptoms. However, to see the inflammation for the doctor is half the battle. Most importantly, what the analysis is to determine the nature of the changes (benign or malignant) in male gland at a very early period of their appearance.
What is the PSA test?
PSA stands for prostate-specific antigen. It is a substance of protein nature produced in the gland as a component of the secret. The antigen responsible for the breakdown of large molecules of proteins, makes thinner sperm and affect the motility of the sperm.
A large part of the protein concentrated in the seminal fluid. And only a small amount entering the bloodstream, participates in the normalization of the functions of the testicles, bladder, male libido.
- for a week to exclude sex;
- after seeing the urologist and palpation must be maintained for two weeks;
- after the biopsy, doing a pause for a month;
- approximately 8 hours for banned coffee, alcohol and even juice and tea.
An important factor in determining the amount of PSA is the age men. For men of different ages in the norm of substances in the blood are different:
- for 40-49 years - indicator takes values of 0-2. 5 ng per ml;
- for 50-59 years of age - antigen is increased by one and is equal to 0-3,5 ng / ml;
- for 60-69 years of PSA is 0-4,5 ng per ml;
- for men, have passed for 70 years of living abroad - 0-6,5 ng per ml.
When is the differential diagnosis of adenoma and prostate cancer, focuses on the ratio of indicators such as free and total antigen. In cancer of the male gland significantlyan increasing number of common substances, whereas the production of free falls. Which corresponds to the ratio of 1 to 10.
In case of BPH is considered a normal situation in which the value of the antigen rises more than 0.75 ng/ml for the whole year.
Greater growth rate characterizes the situation with malignant degeneration of the gland.
PSA density is a significant indicator of differential diagnosis and is calculated as the ratio of protein to the whole prostate volume. The density of protein shall not exceed 0.15 ng/ml. Otherwise the doctor will suspect the presence of tumors. Critical value is considered equal to 10 ng/ml.
