Chorionic gonadotropin
Today, almost all women who have a delay in menstruation, make a pregnancy test. But few people know that he reacts to chorionic gonadotropin in the urine.
It is produced after embryo implantation. Chorionic gonadotropin rises in the blood of a woman after fertilization in a week.
This analysis is the gold standard indiagnosis of pregnancy in the early term. This hormone in the first trimester supports the functioning of the yellow body and promotes the production of estrogens and progesterone, which are necessary for the normal development of pregnancy.
In the future, a system of fetal placenta appears,which begins itself to form a hormonal background. The number of chorionic gonadotropin in the first weeks of bearing the baby every two days is doubled. Then the rate of growth of the level of this hormone should decrease.
The concentration of the chorionic gonadotropin becomes maximal by 10 weeks. Later, his level slowly decreases. Any abnormality is an alarm.
Therefore, human chorionic gonadotropinIt is used not only to detect pregnancy, but also helps to detect various pathologies of gestation and fetus. If a woman becomes the mother of several babies, then his level increases proportionally.
In addition, the increase of this hormone in men and non-pregnant women is an extremely alarming symptom. This occurs with some cancer.
The causes of the analysis for chorionic gonadotropin:
- Diagnosis of testicular tumors, bladder skidding, chorionepithelioma;
- threat of miscarriage and suspicion of an undeveloped pregnancy;
- dynamic observation of the carrying of the baby;
- evaluation of the completeness of abortion;
- suspicion of ectopic pregnancy;
- amenorrhea;
- diagnosis of fetal malformations.
In women waiting for the baby, the hormone can be increased in the following cases:
- receiving gestagens;
- wrong time;
- malformations and pathologies of the fetus;
- diabetes maternal diabetes;
- gestosis, toxicosis;
- Multiple fetuses.
In non-pregnant women and men, chorionic gonadotropin can exceed the norm for the following reasons:
- taking drugs that contain it;
- chorion carcinoma;
- bladder skidding;
- neoplasms of the kidneys, uterus, lungs;
- tumors of the stomach, intestines and testes;
- several days after the abortion.
In women waiting for a child, the concentration of the hormone can be reduced in the following cases:
- death of the fetus;
- delay in fetal development;
- ectopic and undeveloped pregnancy;
- wrong time;
- risk of miscarriage;
- pregnancy overstretch;
- placental insufficiency.
It is important to remember that only a qualified physician can decipher the analysis. Perhaps, it will have to be submitted more than once, in order to trace the dynamics and eliminate the error.
Chorionic gonadotropin should be determined in the blood in the morning on an empty stomach. When taking any hormonal medications, you must notify a doctor about this.
Chorionic gonadotropin, norm:
- non-pregnant women and men - from 0 to 7;
- 1-2 weeks - from 27 to 158;
- 2-3 weeks - from 103 to 489;
- 3-4 weeks - from 1112 to 31502;
- 4-5 week - from 2562 to 82302;
- 5-6 weeks - from 23102 to 151002;
- 6-7 week - from 27302 to 23302;
- 7-11 week - from 20902 to 291002;
- 11-16 week - from 6142 to 103002;
- 16-21 weeks - from 4,722 to 8,0102;
- 21-39 week - from 2702 to 78102.
However, these values are average and depend on the selected laboratory. Weeks of pregnancy must be counted off from conception. The concentration of the hormone is determined in the blood taken from the vein.
If the patient is forced to take the analysis not in the morning, thenBefore coming to the laboratory it is necessary not to eat 6 hours. For early diagnosis of pregnancy, blood must be taken after a delay in menstruation for several days. And after a couple of days, you need to repeat the study.
Thus, the chorionic gonadotropinis an important marker of not only the presence of pregnancy, but also its normal course. In addition, it is used in the diagnosis of various tumor processes in women and men.
