Designation of a common and free dog

A specific substance (antigen) is of a protein nature and is produced by the cells of the prostate gland. It is an enzyme that is part of the semen. The joint value rate indicates the amount of enzyme. The dog is common and antigen free, what is it?

In European countries, the concentration of the dog in this screening test together with x-rays on the organs of the thoracic region. Definition of the test is recommended annually for men over 45 years of age. This procedure allows you to reduce the number of deaths from malignant tumors on the prostate. In our country, the analysis of the dog is carried out only in a paid laboratory department.

Typical clarifications

The dog is common and free, the definition of what it is. The main function that the antigen possesses is liquefaction of condensed sperm with irrigation of the urinary canal during erection, making it easier for sperm to pass through the uterine cavity.

A canine tumor marker is not done in order to determine the quality of sperm. This test is carried out in order to exclude pathological processes in the prostate gland

The ratio of the dog has increased indicators for various pathologies:

• chronic prostatitis;
• adenoma;
• acute prostatitis.

The ratio of the general and free dog does not determine the development of the oncological process. Moreover, with oncology, the enzyme most often has normal values. A more accurate definition is obtained by comparing fractions, the accuracy of the result depends on this.

Determination of the antigen level is shown in the following studies on:

• diagnostics of a malignant neoplasm;
• control of processes during therapeutic therapy;
• for detecting tumor recurrence (after therapy and annually);
• diagnosing the processes of inflammation of the prostate and adenoma (with characteristic symptoms: frequent urge, feeling of incomplete emptying, decreased erection).

Tumor markers of a dog, their decoding are carried out as a preventive screening at the request of a man. This is especially necessary in cases where there is a risk of developing cancer, hyperplasia (adenoma), the growth of benign nodes or prostate cancer in a close relative. The result is decrypted only by a specialized specialist.

Fractional indicators

The psa ratio takes into account free and total matter. What are their differences? A specific antigen is produced by the cells of the gland, after which it penetrates into the sperm. A small amount of protein enters the plasma, where it combines with other proteins (which determines the coherent dog). A small portion enters the bloodstream. This dog means free.

To detect the process of tumor formation, the relative calculation of the fraction is determined, because cancer cells can secrete a modified antigen, and it, in turn, is poorly bound to plasma proteins. When a tall dog is connected, it warns of benign changes in the gland.

How the results are calculated

The dog's rate for men is calculated based on two tables. One determines the number of dogs with a reference interval, and the second evaluates the ratio.

• up to 45 years old - 0-2.4 ng;
• 50-62 - 3.4-3.9 ng;
• 62-68 - up to 4.4 ng;
• 70-80 - up to 6.4 ng.

If the dog is tall, this is due to the occurrence of chronic prostatitis or prostate adenoma. A dog above normal is found in patients who did not follow the rules for preparing for testing. The results will be more meaningful if patients eliminate all negative factors

An increased ratio of free to common canine means prostate cancer

What is the calculation? When calculating the antigen is free, it is divided by the indicators of the total dog and multiplied by one hundred percent.

• up to 10% in a cancerous formation in 57% of the male half;
• 10-16% in 27% of patients;
• 15-22% in 22% of men;
• 20-26% in 15% males;
• over 26% in 7% of the male population.

Normal analysis of a free dog and a common dog is 16% or more. As you can see, the aggregate of 25% levels (low percentage of non-binding) does not have a 100% guarantee that there will be no cancer. This suggests that the increased results do not have a clear criterion for the presence, as well as the absence of tumor formation. To establish a clear diagnosis, a comprehensive assessment is carried out with the appointment of other studies (ultrasound examination of the prostate gland, general blood test).

The combination of analysis (free dog and general) allows the specialist to conduct a final biopsy (histological examination) to find cancer cells. If the general dog is increased or the indicators of the linked dog are reduced, the interpretation of the analysis is not done.Only joint indicators and in the ratio from the general to the related are subject to determination.

When is a dog promoted?

To get a more accurate test result, it is necessary to exclude some of the factors acting on the body, in which the dog is elevated.

With an increased dog due to a pathological process, the specialist recommends to undergo medical therapy. Increases and decreases in indicators are interpreted by a specialized doctor. The specialist relies on other studies and data from previously submitted analyzes. The ratio of the indicator of free and total dog, can be modified during the course of treatment. Often, at the very beginning of therapeutic manipulations, there is a sharp jump. This is due to the irritating effects of medications that are necessary in the treatment of the prostate gland

The free or cumulative increase in the dog has various reasons. When the analysis data is determined by an elevated prostatic, specific antigen of the general or associated, it is not necessary to immediately panic. You should seek help from a specialized specialist. He will help you find the cause and recommend further action.

To get a correct test result, you should not eat for at least 12 hours

Only ordinary water can be consumed from liquid. Exclude the consumption of fried, smoked, fatty and salty foods from the diet for a week. It is advisable not to eat meat. You can not drink strong tea, coffee and take alcohol, even the weakest.

You can eat lean soups in vegetable oil and porridge. Boiled vegetables, not sour fruits are recommended. Heavy physical activity, including sports, is excluded 10 days before the test.

Additional tips

First of all, each person is responsible for his own health. To determine developing cancer at an early stage, an annual, preventive examination is required.

Especially, this applies to men after 40 years of age, in whose families there have already been cases with prostate cancer. The dog's rate must be controlled. It is recommended for all older representatives (after 50) to take an analysis of the dog annually. If an indicator is found that is not acceptable to the standards, it is necessary to consult a urologist. This will help determine early diagnosis.

Do not panic if the analysis figures are not acceptable to the norms

This does not always mean a pathological process. If, nevertheless, a malignant disease is detected at the initial stage, then this process is always 100% cured. Further, it is only necessary to monitor the situation annually.

There are many useful videos on the Internet about the canine tumor marker technique, as well as about other existing markers. There are many lectures on the significance of these tests.

Don't be afraid to check your health for strength. Such actions can help not only to identify the cause of the pathology in time, but in many cases save lives. It is better to prevent diseases than to fight them later. Timely treatment saved many lives, and a timely dog test helped in this.
