How much hcg value determines the placenta residue

Retained placenta is a dangerous condition during childbirth. The embryo is usually delivered out of the body about 5-15 minutes after the baby is delivered from the birth canal, and no later than 30 minutes. At this time, if the embryo is not completely expelled and part of it remains in the uterus, it is called retained placenta. In most cases, what remains in the uterus are very tiny embryonic fragments that are difficult to detect, which are called placental remains.

What is the hcg value to determine the residual placenta

Simply by measuring the HCG value, there is no way to tell whether the patient has retained placenta. HCG measurement is mainly an auxiliary examination method. When the patient's color ultrasound shows that there is residue in the uterine cavity, checking HCG can help determine the specificity of the residue and help determine whether the patient can use drugs to promote the excretion of the residue or needs to undergo curettage and curettage for treatment. Generally, if the residue is not very large and the HCG value is very low, pathological curettage can be performed; if the HCG value is very high, curettage is generally required for treatment. Simply checking the HCG value cannot determine whether the patient has placental residue, because a low HCG value does not mean that there is no residue. If the patient's residue is non-specific, the HCG value may be low, but the residue may exist. A high HCG value does not mean that the patient must have residual disease, because when the patient has trophoblastic disease after delivery, the patient's HCG level may be high, but this situation is not residual disease, but a disease.

Will the placenta retain hcg be high?

Placental residual hcg will be high. The embryo is usually delivered out of the body about 5-15 minutes after the baby is delivered from the birth canal, and no later than 30 minutes. At this time, if the embryo is not completely expelled and part of it remains in the uterus, it is called retained placenta. HCG is what we often call human chorionic gonadotropin. The standard value of human chorionic gonadotropin can immediately tell us the condition of pregnancy. The residual HCG in the placenta blood should be high. If there is any residue, the uterine curettage should be performed as soon as possible, and anti-infection treatment should be given in time. Therefore, the residual HCG in the placenta will be high.

What is Hcg

hCG generally refers to human chorionic gonadotropin. Human chorionic gonadotropin is a glycoprotein metabolized by the trophoblast cells of the embryo and is composed of α and β dimers of glycoprotein. Human chorionic gonadotropin (HCG) αβ, produced by trophoblasts.

Human chorionic gonadotropin enters the maternal blood after fertilization and multiplies rapidly until the 8th week of pregnancy, then slowly decreases in concentration until the 18th to 20th week, and then remains there for a long time. Generally, a level of at least 2.5 MoM of human chorionic gonadotropin is associated with Down syndrome. However, the actual human chorionic gonadotropin level in the maternal blood of DS patients is only 1.3 MoM on average, which cannot significantly distinguish DS patients. The human chorionic gonadotropin-related molecules used for DS testing include dispersed b-hCG and high-sugar and high-calorie hCG (H-hCG).

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. All human chorionic gonadotropin is produced by the transformed germ cells of the embryonic hCG. Human chorionic gonadotropin is produced by a fusion of germ cell transitional somatic cells and germ cells. Human chorionic gonadotropin begins to be metabolized 10-14 days after pregnancy.
