What is the reference value of progesterone 21 days after transplantation?

Whether it is a test tube or a normal pregnancy, the progesterone value is very important. The higher the progesterone value, the better it is for the body. Progesterone is a hormone that promotes the growth and development of the baby in early pregnancy. If the hormone value is low, there will be a risk of miscarriage, and usually the fetus needs to be preserved. The progesterone value changes every day in the early stage, but it shows an increase.

What is the normal hcg level 21 days after transplantation?

Human chorionic gonadotropin (hCG) is a glycoprotein secreted by trophoblast cells of the placenta, which is composed of α and β dimers of glycoprotein. The complete hCG is produced entirely by the syncytiotrophoblast of the placental chorion. Its main function is to stimulate the corpus luteum, which is beneficial to the continuous secretion of estrogen and progesterone, so as to promote the formation of uterine decidua and make the placenta grow and mature.

After the fertilized egg of a mature woman moves to the uterine cavity and implants, an embryo is formed. During the process of development into a fetus, the placental syncytiotrophoblast cells produce a large amount of human chorionic gonadotropin (hCG), which can be excreted into the urine through the blood circulation of the pregnant woman. A simple test of hcg value can be done by testing urine.

What is the normal range of hcg? The normal value of blood hcg is <10μg/L, and the normal value of β-HCG is <3.1Iμg/L, which are within the normal range. Generally, the β-hcg radioimmunoassay value of a normal person is less than 3.1Iμg/L. If it exceeds 5μg/L, the possibility of conception can be considered. If it exceeds 10μg/L, pregnancy can be basically confirmed. 35-50 days after pregnancy, hcg can rise to greater than 2500μg/L.

What is an abnormal hcg value?

The hcg value can be used to measure whether a woman is pregnant, the gestational period of pregnancy, whether it is an ectopic pregnancy, etc. The hcg value is measured through a blood hcg test. The accuracy of this test method is much higher than the hcg value. So what is an abnormal hcg value?

1. Ectopic pregnancy: In the case of ectopic pregnancy, this test has only a 60% positive rate. hCG may still be positive 3 days after uterine bleeding, so hCG examination can be used to differentiate it from other acute abdominal diseases. hCG is usually 312-625 IU/L.

2. Diagnosis and treatment of miscarriage: In case of incomplete miscarriage, if there is still placental tissue remaining in the uterus, the hCG test may still be positive. In the event of complete miscarriage or fetal death, hCG turns from positive to negative, so it can be used as a reference for pregnancy preservation or aspiration treatment.

3. Premature abortion: If the hCG level in urine remains high, inevitable abortion will not occur. If hCG is below 2500 IU/L and gradually decreases, there is a possibility of miscarriage or stillbirth. When it drops to 600 IU/L, miscarriage is inevitable. During the treatment to preserve pregnancy, if hCG continues to decrease, it means that the pregnancy preservation is ineffective. If hCG continues to rise, it means that the pregnancy preservation is successful.

4. 4 days after delivery or 13 days after artificial abortion, serum hCG should be lower than 1000 IU/L. 9 days after delivery or 25 days after artificial abortion, serum hCG should return to normal. If this situation is not met, the possibility of abnormality should be considered.
