What produces beta hCG in placenta?

Human chorionic gonadotropin is a hormone produced primarily by syncytiotrophoblastic cells of the placenta during pregnancy. The hormone stimulates the corpus luteum to produce progesterone to maintain the pregnancy. Smaller amounts of hCG are also produced in the pituitary gland, the liver, and the colon.

What is secret hCG?

Photo showing a urine sample that has tested positive for human chorionic gonadotropin (hCG). This hormone is secreted by the placenta in pregnant women. Human chorionic gonadotrophin is a hormone produced by the cells that surround the growing human embryo; these cells will eventually go on to form the placenta.

What is the target cell of hCG?

hCG promotes the differentiation of cytotrophoblast cells to syncytiotrophoblast cells and so the villous structures which are mixture of the two cell types are formed. hCG also promotes the uterine vasculature to maximally provide blood to the hemochorial placentation structure.

What is the structure of hCG?

Description. Human chorionic gonadotropin (hCG) is a dimer consisting of a 145 amino acid beta-subunit that is unique to hCG and a 92 amino acid alpha-subunit. The alpha-subunit is identical to that for luteinizing hormone (LH), follicle-stimulating hormone (FSH), and thyroid-stimulating hormone (TSH).

What is the beta hCG level at 4 weeks?

The average levels of hCG in a pregnant woman’s blood are: 3 weeks: 6 – 70 IU/L. 4 weeks: 10 – 750 IU/L. 5 weeks: 200 – 7,100 IU/L.

What is a normal free beta hCG level?

normal 1.06, 95 per cent CI 0.89-1.20) were lower and free beta-hCG subunit measurements (1.13 MOM, 95 per cent CI 0.93-2.63 vs. normal 0.91, 95 per cent CI 0.79-1.03) were higher at statistically significant levels.

What is the Beta-hCG level at 4 weeks?

What is a normal hCG MoM?

Results: The mean and median values of hCG were 57,153 mIU/ml and 50,120 mIU/ml, respectively, at 15 weeks of gestation and then decreased to 30,898 mIU/ml and 26,226 mIU/ml, respectively, at 21 weeks. We found 8.6% and 9.4% of normal singleton pregnancies have hCG MoM values >2.0 MoM and <0.5 MoM, respectively.

What is beta hCG?

Beta hCG, also known as quantitative serum beta-HCG, refers to the testing of the amount of hCG hormone present in the blood. Your doctor may order a beta hCG if a urine test came back positive, or, if you’re in the middle of fertility treatments, just before or when your period is due. hCG is measured in milli-international units per milliliter.

How much does a beta hCG test cost in India?

Chances of infection are rare but might happen in exceptional cases. What is the price for a Beta hCG test in India? The cost of a quantitative Beta hCG test in India varies between Rs 450 to Rs 800, depending on the location and the facilities used for the test.

Why would a doctor order a recheck for beta hCG test?

The doctor can also order a recheck in case you have continuous symptoms like bleeding, severe cramping, or a history of miscarriage. The decreased or back to normal levels of hCG also helps the doctor to ascertain that a particular treatment is working positively. Do I need to fast for the Beta hCG test? Fasting is not necessary for this test.

What are beta-hCG levels used for in pregnancy?

Beta-hCG levels may be used in three ways in the clinical setting of pregnancy: Outside the pregnancy setting, it may also be used quantitatively as a tumor marker, to aid in diagnosing a potentially beta-hCG secreting mass (e.g. choriocarcinoma ).
