There is no need to use test strips when HCG is over 20,000 dollars.
HCG is a normal hormone produced in the body after a woman is pregnant, mainly secreted by placental trophoblast cells and cannot be obtained from food. The egg combines with the sperm to form a fertilized egg, and it is only in the 3-4 days after the fertilized egg has been deposited that HCG is secreted in large quantities in the body, and the changes in the blood are relatively obvious.
Generally, pregnancy can be detected in 10 days after intercourse, while the HCG changes in urine are relatively insignificant, and pregnancy can be detected in about 15 days or even later. So clinically the blood HCG test more than 20,000 has been clearly pregnant, so there is no need to use early pregnancy test paper.
After pregnancy, if the embryo development is normal, every two days to check the blood HCG value is doubled, if the embryo development is not normal or ectopic pregnancy, the blood HCG value will not be doubled, or even very low. When a woman is suffering from hyperemesis gravidarum, choriocarcinoma, etc., the blood HCG value will be abnormally high.
Therefore, it is necessary to monitor the blood HCG value regularly after pregnancy to know whether the embryo is well developed or not, and it is not necessary to use the pregnancy test paper after diagnosing pregnancy.
