How many days can I know I'm pregnant by taking a blood test?

Most women who are preparing for pregnancy know how to detect early pregnancy, and many women choose to buy their own pregnancy test sticks to test pregnancy. However, too many women will actively go to the hospital for blood tests after they find out they are pregnant. It is said that blood tests are the most accurate way to detect early pregnancy. So how many days in the early stages of pregnancy should a blood test be done? What are the advantages of smoking to check early pregnancy? First, let us understand what a blood test is. The professional name of blood test is blood HCG test.

It determines whether a woman is pregnant by accurately measuring the HCG value in her blood. Generally, pregnancy can be confirmed by drawing blood for HCG test 8-10 days after intercourse.

Generally speaking, urine HCG tests such as early pregnancy test strips can only be tested one week after the menstruation stops, while blood HCG pregnancy tests can usually be tested one or two days after the menstruation stops. This can advance the time of confirming pregnancy, so that corresponding preventive measures can be taken against pregnancy earlier.

Advantages of blood tests for early pregnancy

Compared with traditional urine tests, blood HCG is more accurate and has a smaller deviation, so doctors generally recommend blood tests for HCG pregnancy tests. Checking HCG value through "quantitative analysis" of blood can reflect pregnancy more sensitively and accurately than using general pregnancy test paper to "judge" urine, with an accuracy of over 99%.

In addition, for multiple pregnancies, ectopic pregnancies, test tube embryo abnormalities, language development delay, hydatidiform mole, some endocrine diseases or tumors, the blood HCG value is combined with clinical conditions and other test results, and a correct diagnosis can usually be made through comprehensive analysis.

Many women are concerned about whether they should be on an empty stomach before having their blood tested for HCG. Experts remind patients that they do not need to be on an empty stomach before having their blood tested for HCG. Whether they are on an empty stomach before having their blood tested has no effect on the test results. As long as women understand the blood HCG pregnancy test, they can accurately check whether they are pregnant.
