Often, a woman goes to the clinic in order to urgently pass pregnancy tests. Impatience to find out about the presence or absence of pregnancy is always understandable, the need to make quick tests can be caused by various circumstances - from family or health-related to domestic.

The analysis of hCG is performed urgently - usually it is ready within 24 hours after delivery, in addition, this blood test shows the presence of pregnancy as early as 6-10 days after fertilization.

This urgent blood test is done according to indications and for men - in relation to them, the results of this express study reveal the presence or absence of a tumor process in the testicles.

What is HCG


In the 1st trimester of bearing a child, hCG provides the formation of progesterone and estrogen necessary for the preservation and development of pregnancy. If a woman is pregnant with a boy, hCG is responsible for hormone-producing Leydig cells that synthesize testosterone, which is necessary for the proper development of the male reproductive system. HCG also affects the development of the adrenal cortex of the embryo.

The study also determines the amount of female hormones from the steroid group, which are produced by the ovaries and are responsible in the development of the female fetus for the subsequent fertility, that is, the established value of the hCG level makes it possible to make reliable perinatal (intrauterine) diagnostics for the presence of pathologies in the unborn child.

Where else is a blood test for the presence of hCG used?


The level of chorionic gonadotropin is used to diagnose amenorrhea - the absence of menstruation over several menstrual cycles, which is important for maintaining a woman's health, since amenorrhea is not an independent diagnosis, but is a symptom of anatomical, biochemical, genetic, physiological and mental malfunctions of the female body.

It is also used for the timely diagnosis of an ectopic pregnancy, and to determine the completeness of the operation for induced abortion.

In men, it allows the diagnosis of testicular tumors, since the trophoblastic elements of the tumors produce hCG. In women, with the help of this study, chorionepithelioma is detected - a malignant neoplasm formed by the epithelial tissues of the chorion during pregnancy or at the end of gestation.

One of the uses of a blood test for the presence of hCG is to identify a cystic drift that interferes with the healthy development of the embryo, when the villi of the embryonic membrane grow to bubbles filled with fluid.

The value of the hCG level indicator - norm and pathology


By the level of this hormone, you can accurately judge the duration of pregnancy at any time of the analysis. The indicator is measured in mU / ml. For each gestational age, the study form will indicate its values ​​by week.

You can compare the results of your research - the actual indicators and the norm - to be sure that the pregnancy is developing normally, you can yourself. In all other respects, with regard to the results, you should rely on the knowledge of the specialist who performed the laboratory analysis and the doctor who makes a diagnosis based on the data obtained.

Since an increase or decrease in hCG occurs for various reasons, and only a qualified medical professional using digital indicators can correctly assess the degree of danger and neglect of the pathology, which is indicated by an indicator that lies outside the norm.

Pathologies indicated by the hCG indicator


During the gestation of a child, an increase in chorionic gonadotropin indices relative to the norm occurs with multiple pregnancies (the indicator increases in proportion to the number of fetuses); toxicosis and gestosis; if the expectant mother has diabetes mellitus; numerous developmental disorders of the child. HCG may be higher when the fetus has Down syndrome.

A low hCG level in pregnant women means either an incorrectly set gestational age, or is a sign of a serious pathology, such as:

  1. ectopic pregnancy;
  2. delayed intrauterine development;
  3. retraining for a longer period.

Low hCG is also characteristic for a frozen pregnancy. If pregnancy is threatened with spontaneous miscarriage, the level of the hormone drops to 50% or lower. Lowered hCG in chronic placental insufficiency; in the second or third trimesters of pregnancy - if the fetus died in the womb.

HCG out of range in men and non-pregnant women

Exceeding the normal level of hCG is evidence of a serious health disorder in non-pregnant women and men, and may indicate the following pathologies:

  • malignant neoplasms of the testicles;
  • cystic drifts, and, as a result, chorionicarcinoma (trophoblastic tumor that develops as a result of malignant transformation of the epithelium of the uterine chorion) in women;
  • neoplasms of the digestive system (stomach and intestines), lungs, kidneys.

The procedure for donating blood for hCG and preparation for blood sampling for analysis

To study the indicator of the hormone, blood is taken from a vein. It should be taken in the morning on an empty stomach. If the blood sampling procedure is not performed in the morning, then food should not be taken for four to six hours before taking the test.

If the patient is taking hormonal drugs, he should inform the doctor about it. The test results are usually ready one day after the analysis.
