What does a positive pregnancy test mean?

I believe that every expectant mother who has gone to the hospital for a pregnancy check-up knows that Hcg is one of the criteria for determining whether a female friend is pregnant. There are two types of hcg, positive and negative. Today, let's talk about hcg positivity. What does it mean if hcg is positive? What does a positive pregnancy test mean?

What does hcg positive mean

Urine 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 you are pregnant. Normal non-pregnant women show negative test results, while pregnant women show positive test results. Generally, a urine pregnancy test will be positive 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

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 case of incomplete miscarriage, there is still embryonic tissue remaining in the uterus, and HCG is positive. In case of 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 means 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, choriocarcinoma and testicular teratoma in men, the urine HCG component is very high, reaching 100,000 to tens of millions of international units.

4. Others: HCG changes differently during pregnancy toxemia, and the value is usually high; HCG components increase during multiple pregnancies.

What does a positive hcg test mean? A positive hcg test means you are pregnant and a new life is about to be born. However, during pregnancy, the hCG values ​​of many expectant mothers do not reach the standard range or exceed it. These are very dangerous and should be paid attention to. Therefore, expectant mothers should also properly understand the problems of HCG measurement.
