Everyone has had to donate blood at least once in their life. Of course, this is not a very pleasant procedure, but in some cases it is indispensable. A blood test is performed before any surgical intervention, after a long and serious illness, upon discharge from a medical institution. Immediately after birth, babies undergo a blood test for existing congenital pathologies. All pregnant women also repeatedly donate blood during the period of bearing a child. There are many varieties of her research:

  • general analysis;
  • biochemical study;
  • determination of Rh and group;
  • blood test for hCG and other hormones;
  • research of the material for coagulability.

Why donate blood?

In most cases, the doctor prescribes the analysis necessary for the study. It is necessary to pass it in order to assess the state of he alth and the human body as a whole. The material can be taken from a finger or a vein, depending on what needs to be examined. In babies, after birth, blood is taken from the heel. It is also possible to take material from veins on the head, arm, foot or hand.

What is HCG?

Chorionic gonadotropin is a substance found in the body of a pregnant woman. In the absence of pregnancy in the fair sex, a low level of hCG in the blood can be detected. This is a variant of the norm and does not require any treatment and medical intervention. The exception is a significant increase in the level of the hormone.

The moment fertilization occurs, the level of hCG in the blood begins to rise. The maximum amount of this hormone reaches the twelfth week of gestation. After that, it begins to gradually decrease and by the time of delivery reaches the lower limit. You can see the growth rates of human chorionic gonadotropin in the table below. It can be used to track how the hormone grows and how it decreases in its value.

Horionic gonadotropin got its name due to the fact that the chorion is responsible for its production, which acts on the produced female sex hormones in a special way. He completely adjusts them for himself, creating favorable conditions for the development of the embryo.

How does HCG work?

Chorionic gonadotropin has a powerful force, which is several times greater than the force produced by female hormones. It makes the ovaries rewire and work in a completely different way.

hCG suppresses monthly ovulation and follicle growth. It also blocks the production of hormones that contribute to the renewal of the endometrium and the onset of menstruation. Chorionic gonadotropin provokes the production of a large amount of the hormone progesterone, which is necessary for the normal development of pregnancy.

Also, HCG affects the nervous and immune systems of women. It helps her cope with stress and somewhat reduces immunity. This is necessary so that the mother's body does not perceive the fetus as a foreign body and does not reject it.

How to determine hCG?

In our time of modern technology, there are several methods for determining the presence of this hormone in the human body:

  1. using pharmacy test strips;
  2. blood test for hCG.

Test for home use

Of course, using a test system to determine the presence of this hormone is easier. Also, this method has a fairly low cost. However, it is not always accurate.

The hCG hormone is produced from the moment of fertilization of the egg by the sperm. At this stage, the strip strip for home use will probably still show a negative result. Therefore, it is recommended to use this diagnostic method only when there is a delay in the next menstruation.

You will need a small amount of urine to perform the test. In it, the concentration of the hormone is slightly lower than in the blood. Therefore, such a system may fail and show incorrect results. Urine sampling is best done in the morning, preferably immediately after waking up. In this case, you will get the most accurate result.

HCG blood test

In the blood, the level of the hormone is at the same level, regardless of what time of day the test is taken. This method is less convenient and more expensive than the first option. However, in this case, you will receive the most accurate and reliable result of the study. You can donate blood every other day. Then you will accurately track the increase in the amount of chorionic gonadotropin in the body.

How to donate blood for hCG

The material is taken from a vein. It is the study of this blood that helps to identify the maximum level of chorionic gonadotropin in a woman's body. Usually the vein located in the crook of the arm is selected, however, if it is not possible to take material from there, you may be offered to use the vein located in the hand.

Most often, the material is taken by a nurse or a laboratory assistant. A woman is put on a tightening tourniquet on the forearm area, after which they are asked to “pump up” the vein a little, squeezing and unclenching the brush. When the doctor sees that the vein is sufficiently inflated, he draws blood.

A thin needle is inserted into the vein, to which a special device with a pump mechanism is attached. Thanks to him, the test tube is quickly filled with red liquid and the needle is removed from the vein. Also, blood sampling can be done with a conventional syringe, but this method has recently been used less and less in medical institutions.

It is necessary to observe all sanitary standards and caution when taking the material. Before piercing the skin with a needle, wipe its surface with cotton wool soaked in alcohol. This will help prevent pathogenic microbes and various bacteria from entering the vein.

Preparation for analysis

Before donating blood for hCG, do not eat or smoke. This condition must be observed in order to obtain the correct result. It is also not recommended to be nervous and drink coffee. On the night before sampling, you need to sleep well and be in a good mood. In this case, you will get the most accurate result.

Blood is taken mainly in the morning. It is at this time of day that the level of chorionic gonadotropin in the blood has a maximum level. Before entering the treatment room, sit in front of it for a few minutes, catch your breath, calm down, tune in to a positive mood, and only after that go in to donate blood.

Indications for testing

Since they donate blood for hCG usually in the direction of a doctor, there are some indications for such a study:

  • suspected ectopic pregnancy;
  • the possibility of developing malignant tumors;
  • early detection of pregnancy;
  • suspected non-developing pregnancy or anembryony.

Getting the result

Usually, the analysis is prepared no more than two days. The result of a blood test for hCG can be deciphered by a doctor, but usually the laboratory standards are always indicated on the result sheet. This is done for the convenience of the patient. A woman can independently determine what parameters her result fits into.

Result of analysis Laboratory standards (mU/ml)
Men of all ages 0 to 2.5
Women of any age 0 to 5
Pregnancy
First week from conception From 16 to 165
Second week from conception From 101 to 4870
Third week from conception From 1110 to 31500
Fourth week from conception From 2560 to 82300
Fifth week from conception From 23100 to 151000
Sixth week from conception From 27300 to 233000
From the seventh to the tenth week From 20900 to 291000
From the eleventh to the fifteenth week From 6140 to 103000
From the sixteenth to the twentieth week From 4720 to 801000
From the twenty-first week to the time of delivery From 2700 to 78100

Horionic gonadotropin above normal

If the blood tested for hCG results are higher than normal, this indicates pregnancy. In the first days of embryo development, the level of the hormone doubles every other day. This happens on average until the twelfth week.

If the analysis showed a very high result, then this may indicate a multiple pregnancy. In this case, the hCG level increases in proportion to the number of embryos in the uterus.

Also, a strong increase in chorionic gonadotropin during the period of bearing a child can indicate pathologies such as diabetes in the mother, late toxicosis, various malformations in the formation and development of the baby's organs.

After the twelfth week, a blood test is carried out for the amount of chorionic gonadotropin. This is necessary in order to identify possible fetal malformations.

Chorionic gonadotropin below normal

If donating blood for hCG went according to all the rules, but the result is significantly underestimated, then there may be the following pathologies:

  • pregnancy outside the womb;
  • Missed pregnancy or threatened miscarriage;
  • improper development of the embryo or delay in its growth;
  • intrauterine fetal death (second and third trimester);
  • disorders in the placenta.
  • blood hCG level

If you get a result that indicates a low level of hCG, then most likely you will be assigned a second analysis, as well as a number of additional studies.

Choice of clinic and price of analysis

Now there are quite a few private laboratories that offer research of various kinds. If you are wondering where to donate blood for hCG, then first conduct a price analysis. The cost of the service can vary from three hundred rubles to one thousand. The timing of the study may also differ. Some clinics promise results within a few hours. Other laboratories provide it only after a few working days. Of course, the speed of work of some laboratories pleases, but for sure the cost of such an analysis is somewhat overestimated. And rightfully so.

You can also conduct a study in a public medical institution. To do this, you need to get a blood test for hCG from your doctor. The price in this case will be minimal for you, or the analysis will generally be free. However, be prepared for the fact that the result will have to wait from several days to one week. Sometimes it is easier for a woman to pay than to suffer while waiting for the result of the analysis.

Conclusion

Now you know how to donate blood for hCG. If analysis is required, pay attention to the choice of laboratory and proper preparation for material sampling. If the result is unsatisfactory, retake the analysis. Do not be nervous, this can adversely affect pregnancy. There are times when labs get it wrong. If the repeated result was not as expected, then you should consult a doctor for a consultation and possible correction.

Keep your well-being under control and be he althy! Get tested on time and follow all the recommendations of a specialist you trust.
