What is the hcg value for twins

During pregnancy, many women only have one baby, but some women have twins. People are very hopeful about twins and will do some tests during pregnancy. HCG tests are very common. So what is the HCG value for twins?

What is the hcg value for twin babies

Medical clinical studies have shown that in the early stages of pregnancy, the progesterone and HCG levels of women carrying twins are higher than those of women carrying one baby. For example, at 7 weeks of pregnancy, the progesterone level exceeds the standard value of 52.7-100.1nmol/L. Of course, the value of this indicator can only be seen during a physical examination in the hospital. The twin babies also have the following symptoms:

1. The abdomen is larger than a normal pregnancy with twins. One of the early symptoms of twin pregnancy is a noticeable abdominal protrusion. For many women, the abdomen is not noticeable in the early stages of pregnancy. Pregnant women carrying twins are more prominent, especially after 24 weeks of pregnancy. Whether the baby is twins can also be determined by the size of the uterus. If the uterus grows too fast relative to the delivery period, it may be suspected to be twins.

2. The phenomenon of early pregnancy is serious. The vast majority of pregnant women experience early pregnancy reactions, some of which are severe and some are mild. However, mothers pregnant with twins suffer from severe early pregnancy symptoms, and may experience varying degrees of nausea, vomiting, picky eating, and habitual vomiting. In the later stages of pregnancy, symptoms of compression such as panic, difficulty breathing, swollen legs and feet, and varicose veins may continue to occur.

3. More than one heart rate. As the pregnancy progresses, the symptoms of twin pregnancy will become more and more obvious. For example, you can feel 2 fetal heads and 2 fetal buttocks, and hear 2 fetal heart sounds. Expectant mothers can have ultrasound and X-ray examinations to measure the different speeds of the fetus' heart waves and see the bones of the two fetuses.

The triangular relationship between HCG, progesterone value and miscarriage

Condition 1: HCG doubles very well, while progesterone decreases. There is also a situation where HCG doubles very well and progesterone decreases. This shows that the test tube embryo is growing and developing normally, but the effect of HCG progesterone value is not good. For example, there is a term in traditional Chinese medicine called "lung qi deficiency". It does not mean that the lung disease has changed, but that its function is not good. You need to rest and carefully improve the function. The general principle is the same. If the conditions permit in this situation, you should rest and lie down as much as possible. As long as the progesterone level is not very low, you can keep the pregnancy without supplementation.

Condition 2: Progesterone levels are normal, but HCG doubling is not good. In addition, the progesterone value is normal, but the HCG doubling is not good. This situation is rare, because HCG promotes the production of progesterone levels. If HCG is not good, the progesterone level will generally be bad. Many pregnant women say that doubling of HCG is not good, which is all relatively bad. What does it mean? It means that if you measure it on a certain day and the standard value goes up but does not reach the multiplier, with a difference of one hundred or two hundred, then it is relatively not good, definitely not good. The standard value is in a range, for example, 8 days, and it only doubles. This situation is not interesting. First, rule out ectopic pregnancy. Then there may be a problem with the test tube embryo. See the previous paragraph. Nowadays, many hospitals only supplement progesterone levels and rarely supplement HCG, because low HCG may make the test tube embryo itself not good and the value of preserving the fetus is not great.
