Can a woman's blood test reveal her pregnancy?

Before a woman is ready to conceive, both husband and wife should prepare for pregnancy, so that the baby can be healthier. In addition, women can effectively increase the chance of conception by having sex during ovulation. However, since everyone's physical fitness is different, the situation of conception will also be different. There are many ways to detect pregnancy. Many women will need blood tests. So can blood tests detect pregnancy?

First, can a blood test detect pregnancy? Early pregnancy can be diagnosed by testing the blood for HCG 10 days after sexual intercourse. This is currently the earliest and most accurate method of examination. You cannot have a blood test to detect pregnancy three days after having sex. Choose morning urine for self-testing at least 10 days after having sex, as the concentration of hCG in morning urine is higher. It takes several days for sperm and egg to combine into a fertilized egg, implant into the uterus, and form an embryo. hCG will only appear in the blood a few days after pregnancy, and because of the small amount, it may not be detected at the beginning.

Second, it is important to note that although many pregnancy test tools indicate that women can do a pregnancy self-test one day after missing their normal menstrual period, in fact, not all pregnant women release hCG hormones at the same rate and in the same amount. This varies from person to person. If a urine test is done too early, a negative result may be false.

Third, urine test is the most common method of early pregnancy test, and it can be tested at home using early pregnancy test strips or in the hospital. To improve accuracy, it is best to use morning urine test. A positive urine test result proves pregnancy. If it is negative, the test should be repeated after one week. The test results are generally reliable, but in order to rule out ectopic pregnancy, you still need to go to the hospital for examination. The doctor may also recommend a blood test, which is usually used within a week of the menstrual period. The hcg test in the blood can determine whether you are pregnant.

Can a woman's blood be drawn to detect pregnancy? The hCG value can be measured through a blood test 8-11 days after conception. Blood hCG appears earlier than urine hCG, and the blood hCG test is much more accurate. The working principle of using early pregnancy test strips to detect early pregnancy is to detect the hCG value, that is, the value of human chorionic gonadotropin. This hormone is produced by the placenta and usually appears in the urine a few days after pregnancy. However, due to the small amount, it is difficult to test it at the beginning and it only becomes increasingly obvious after 10-14 days.
