What does hcg weak positive mean

What does a weak positive hCG test mean? In response to this question, relevant personnel stated that HCG (hcg gonadotropin) is the growth hormone most known and commonly used as a "pregnancy test" by obstetricians and gynecologists and nurses. Generally, a positive pregnancy test will be shown 35 days after menstruation. So, what does hcg weak positive mean? Let's have a simple understanding of this issue. I hope the following points will be helpful to everyone!

What does a weak hCG positive mean?

Early pregnancy test, also known as early pregnancy test paper test, is based on testing whether there is a certain amount of human chorionic gonadotropin (hCG) in the urine to determine whether the woman is pregnant. Normal non-pregnant women test negative, while pregnant women test positive. Generally, a positive pregnancy test will be shown 35 days after menstruation.

Generally speaking, the standard value of hcg at 30 days of pregnancy is between 1000-50000IU/L. Generally, the β-HCG radioimmunoassay value of ordinary people is lower than 3.1. If it exceeds 5, the possibility of pregnancy can be considered, and if it exceeds 10, pregnancy can be basically confirmed. 35-50 days after pregnancy, hcg can rise to more than 2500IU/L. The urine -hcg level in women with multiple pregnancies often exceeds that in women with a single pregnancy.

Common Problems with HCG Measurement

HCG (hcg gonadotropin) is the "pregnancy test" growth hormone that is known and most commonly used 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 germ cells of the embryonic hCG. Its main function is to stimulate progesterone, which is beneficial to the continuous metabolism of estrogen and luteal copper to promote the formation of uterine decidua and enable the embryo to grow and develop perfectly. It is now believed that HCG is produced by the fusion of germ cell transition 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.

1. Distinguish between normal and abnormal pregnancy: HCG changes during pregnancy show a bimodal curve. According to the normal changes in HCG concentration values, if the first HCG is within the normal range, 79% of people can become pregnant to full term. If the first HCG is significantly lower than normal, 92% of pregnancies will fail.

2. Diagnosis and treatment of miscarriage: In incomplete miscarriage, there is still embryonic tissue remaining in the uterus, and HCG is judged to be positive. In complete miscarriage or fetal death, HCG may be negative. If HCG is below 2500U/L and gradually decreases, there is a possibility of miscarriage or fetal death. When it drops to 600U/L, miscarriage is inevitable. If HCG in urine continues to decrease, it indicates that the pregnancy maintenance is ineffective. On the contrary, it indicates that the pregnancy maintenance is successful. Blood cell HCG should recover 4 days after giving birth or 13 days after an abortion. If this condition is not met, the possibility of abnormality should be considered.

3. In cases of malignant hydatidiform mole, HCG epithelial cancer and testicular teratoma in men, the urine HCG component is very high, reaching 100,000 to tens of millions of standard units.

4. Others: HCG changes differently during pregnancy toxemia and is usually higher; HCG components increase during multiple pregnancies.
