The level of hCG during pregnancy

HCG begins to produce chorion of the embryo after implantation into the endometrium. It is actively used to diagnose pregnancy. It is for the presence of hCG in the urine that a test responds, which helps a woman learn about maternity.

However, this hormone testifies not only to the fact of pregnancy. Its quantity can help to suspect to the doctor many pathologies, including in the development of the fetus. The level of hCG during pregnancy should change in a certain way, it is important even not so much its quantity as the dynamics.

This hormone allows you to learn about motherhood 10 days after fertilization, and sometimes earlier. It is thanks to the release of hCG that a yellow body continues to exist that synthesizes progesterone. Also, estrogens are actively released. The role of hCG in normal pregnancy development is difficult to overestimate.

The laboratory definition of a hormone in the blood is more accurate than the one in the urine. The fact is that it contains less hCG. Therefore, at a very early time, it is better to donate blood.

The level of hCG during pregnancy in the first trimester is constantly growing. The highest concentration is achieved for 10-12 weeks. Then the amount of the hormone decreases and remains constant the second half of pregnancy.

So, the norms of hCG during pregnancy:

• 1-2 weeks - 27-302;
• 2-3 week - 1502-5002;
• 3-4 weeks - 10002-30002;
• 4-5 week - 20002-100002;
• 5-6 week - 50002-200002;
• 6-7 week - 50002-200002;
• 7-8 week - 20002-200002;
• 8-9 week - 20002-100002;
• 9-10 week - 20002-95002;
• 11-12 week - 20002-90002;
• 13-24 week - 15002-60002;
• 15-25 week - 10002-35002;
• 26-37 week 10002-60002.

The unit of measurement is mU / ml. It should be borne in mind that in different laboratories the figures may differ. This is due to the use of different test systems and units of measurement. In nonpregnant hCG should not be more than 5 mU / ml. It should be noted that weeks are counted from the day of conception, not the last menstrual period.

Indications for the appointment of hormone analysis:

• Suspicion of a testicular tumor ;
• Prenatal skinning;
• Diagnosis of bladder skidding, chorionepithelioma;
• Possible undeveloped pregnancy and miscarriage;
• Observation of bearing;
• Assessment of the completeness of abortion;
• Elimination of ectopic pregnancy;
• amenorrhea;
• Early definition of conception.

So, the level of hCG during pregnancy increases in the following situations:

• Reception of progestogens;
• Incorrectly fixed term;
• Down's syndrome, fetal pathologies, malformations;
• Gestosis;
• diabetes;
• Multiplicity (it increases in proportion to the number of fruits).

A high value of ghoul is outside of pregnancy in the following states:

• Immediately after the abortion;
• Choriocarcinoma;
• Taking drugs with hCG;
• Bladder skidding or relapse;
• Neoplasms of the lungs, uterus, kidneys;
• Tumors in the digestive tract.

Low level of hCG during pregnancy is possible with:

• Death of the fetus;
• Placental insufficiency;
• Overstretching of pregnancy ;
• Threat of miscarriage;
• Ectopic and frozen pregnancy;
• Delayed development.

To hand over the analysis it is necessary in the morning and strictly on an empty stomach. It is important to remember that the doctor should interpret the results, taking into account the data of other studies. If a person takes any medications, then it must be warned about it, since this can affect the result of the analysis.

To diagnose pregnancy, it is best to do the study a few days after the delay. To be true, you need to repeat the analysis.

So, the level of hCG during pregnancy depends on the term. He helps to diagnose not only the fact of conception, but also to assess how fully the child's bearing takes place. Mismatch hCG norm can indicate fetal pathologies and even its death.

He is included in the prenatal screening, which every future mother goes through without fail. Analysis for hCG is the most accurate way to diagnose pregnancy. In addition, the determination of the level of this hormone is actively used to detect cancer.
