How many chorionic villus test results indicate pregnancy

Early pregnancy tests require blood tests, urine tests, and tests on extracted secretions. Only after these tests can the results be checked. Many people really want to know how much chorionic villus count in the blood test indicates a positive pregnancy. In fact, this depends on each person's different levels of performance, and requires detailed understanding and recognition. Considering the particularity of the disease, it cannot be detected.

β-HCG (human chorionic gonadotropin) is a glycoprotein secreted by trophoblast cells of the placenta. Early diagnosis of ectopic pregnancy is mainly based on the detection of blood HCG (human chorionic gonadotropin). The normal human β-HCG human chorionic gonadotropin content is about 0-3mIU/ml.

The blood β-HCG ratio can be used as an indicator for judging intrauterine pregnancy, ectopic pregnancy and pregnancy failure; patients with a β-HCG ratio <0.81 are more likely to have pregnancy failure, and patients with a ratio exceeding 1.68 are more likely to have intrauterine pregnancy.

The urine -HCG of women with multiple pregnancies is often higher than that of women with single pregnancies.

Serum HCG should return to normal 9 days after delivery or 25 days after artificial abortion.

If this situation is not met, the possibility of abnormality should be considered.

Early diagnosis of ectopic pregnancy is mainly based on the detection of blood HCG (human chorionic gonadotropin).

Because HCG is a specific hormone secreted during pregnancy, β-HCG can be used to assist in the diagnosis of early unruptured ectopic pregnancy.

The amount of HCG secreted by normally developed villi is very large, and the titer continues to rise rapidly every day, increasing by more than 66% every 48 hours.

If the amount of β-HCG increases by more than 66% every two days, it can be diagnosed as intrauterine pregnancy;

If the increase is less than 66%, there is a high possibility of ectopic pregnancy or intrauterine pregnancy hypoplasia.

For ectopic pregnancy, due to the thin muscle layer of the fallopian tube and poor blood supply, the HCG secretion is very low. The daily appreciation is less.

The increase in 48 hours was less than 50%. (But for some people, the initial HCG rise is normal)

If HCG is difficult to confirm, blood progesterone can be used for auxiliary diagnosis.

It is well recognized that patients with ectopic pregnancy have low blood progesterone levels. Therefore, it can be used as one of the early diagnosis methods.

The critical value is 63nmol/L.

Further B-ultrasound examination can be performed, especially "vaginal ultrasound" examination is very helpful in diagnosing ectopic pregnancy.

After a woman becomes pregnant, elevated levels of β-HCG can be detected in her blood from the 9th to 11th day.

Thereafter, the amount of β-HCG may double every two days (even if there is threatened miscarriage, the rate of increase of HCG will not change).

For example, if today's value is 234, if the test result the day after tomorrow is around 450, it can be considered as normal intrauterine pregnancy.
