Determination of blood group and Rh factor

Blood type is a genetic trait inherited from parents that remains constant throughout life. The division into groups is carried out according to the antigens A and B, located in red blood cells.

The Rh factor is a protein that can be found on the surface of red blood cells. If it is, then the Rh factor is defined as positive. This result prevails in about 85% of all people. If there is no protein, then the Rh factor is negative.

At the Dobrobut MC clinic in Kyiv, you can donate blood for the Rh factor and group quickly, painlessly, and in a comfortable environment. Our laboratory in Ukraine is equipped with equipment from the best world manufacturers, which allows us to generate results with the utmost accuracy.

Why do you need to know the blood type and Rh factor

The need for information usually arises before elective operations and when a person needs a blood transfusion, that is a blood transfusion. The introduction of an inappropriate blood group and Rhesus into the human vascular bed for therapeutic purposes can provoke acute renal failure and lead to the death of the patient.

A blood test for the Rh factor is especially important when planning a pregnancy and carrying a fetus. If it is found that a woman has a negative indicator, and a man is positive, this can cause a conflict on the Rh factor if the fetus takes the father's Rh - Rh +.

In this case, the woman's body may perceive pregnancy as something alien. As a result, the active production of antibodies begins, aimed at the destruction of foreign cells. Antibodies begin to enter the blood of the fetus to destroy Rh-positive red blood cells.

In such a situation, the likelihood of a miscarriage, the development of hemolytic disease in the fetus, increase. Lack of adequate therapy can lead to serious disorders of the brain, liver, and kidneys in a child.

That is why it is so important to donate blood for the Rh factor as early as possible. It should be understood that the risk of Rhesus conflict is not a contraindication for pregnancy.

Consultation with a reproductive specialist, gynecologist, and timely prescribed treatment reduces the risk of developing any complications in the fetus. It's just that a woman should be observed more often and donate blood for anti-Rhesus antibodies every month. Thus, the doctor will quickly determine how the immune system of a pregnant woman with a negative Rh reacts to a fetus with a positive one.

If you are planning a pregnancy, it is important to undergo a preliminary examination 3-6 months before a possible conception, including donating blood for the Rh factor and group. Our clinic MC "Dobrobut" has all the necessary certificates for research.

Indications for the analysis

Your doctor may recommend testing under the following circumstances:

The need for blood transfusion, to match the donor and recipient.
Pregnancy planning, gestation, to exclude the development of Rhesus conflict.
Preparing for a planned operation.
Entering the service in law enforcement agencies (army, police), the Ministry of Emergency Situations, and other departments of a similar nature.

How is the determination of the blood group, Rh factor

For the study, venous blood is needed. It is taken from the cubital vein by a puncture. No special preparation is required. The general conditions must be observed.

Blood is taken on an empty stomach or at least 8 hours after the last meal.
For 24 hours before the test, you should not drink alcohol and food with high-fat content. It is recommended to conduct the study in the morning.

To obtain data, the ABO system, which was developed more than fifty years ago, is used. The method cannot be considered obsolete, since it gives an accurate result, especially since nothing newer for determining the blood group and the Rh factor has not yet been invented. The indicator is determined by agglutinogens - special blood proteins.

What can be the result of the analysis of blood type and Rh factor

The result for the blood type can be as follows:

Group	Note
0 (I) - first	It is established if during the process of agglutination there was no adhesion of erythrocytes with certain antigens in the biomaterial. People with this blood type are considered universal donors. Although in modern medical practice, in order to avoid conflict during blood transfusion, they try to use only the patient's group.
A (II) - the second	It is established when only antigen A is found on the surface of red blood cells. This is the second most common blood type.
B (III) - the third	It is established in the case when only B antigen is present on the blood cells. About 13% of people with such a group.
AB (IV) - fourth	It is established when antigens of both types - A and B are detected on erythrocytes.

The Rh factor will depend on the presence or absence of the D antigen. There can be one of two outcomes here:

Rh + - D antigen is located on the surface of blood cells.
Rh- - antigen D is absent on the surface of erythrocytes.
