What department should I go to for blood test hcg

When pregnant women reach a certain stage, they usually go to the hospital for some body examinations. In some large hospitals, there are many types of examinations that can be performed, but there are also many departments in the hospital. Pregnant women are very confused about making appointments, so which department should they go to for hcg tests?

The hcg test is used to check pregnancy, so it can be done by either a gynecologist or an obstetrician. HCG (human chorionic gonadotropin) is the growth hormone most commonly used as a "pregnancy test" by obstetricians and gynecologists and nurses. It is composed of α and β dimers of glycoprotein. But the α-subunit is the growth hormone produced by the anterior pituitary gland. The β-subunit is specific to HCG. All HCG is produced by the transformed trophoblast of the embryonic chorion. Its main function is to stimulate progesterone, which is beneficial to the continuous secretion of estrogen and luteal copper, so as to promote the formation of uterine decidua and make the embryo and fetus grow and develop perfectly.

It is now believed that HCG is produced by the fusion of trophoblast transitional cells and germ cells. Appreciate rapidly during the first 8 weeks of pregnancy to maintain the pregnancy. After about 8 weeks of pregnancy, HCG levels gradually decrease until they are relatively stable at about 20 weeks. Checking HCG values ​​through "quantitative analysis" of blood can reflect pregnancy more flexibly and accurately than using early pregnancy test strips to "judge" urine, with a success rate of over 99%.

In addition, for multiple pregnancies, ectopic pregnancies, IVF abnormalities, language development delay, hydatidiform mole, some endocrine diseases or tumors, the blood HCG value is combined with clinical conditions and other test results, and a correct diagnosis can usually be made through comprehensive analysis. In addition, the level of human chorionic gonadotropin-related molecular structures is also related to the identification of fetal sex. The level of human chorionic gonadotropin in baby girls is significantly higher than that in baby boys.
