Is blood test for early pregnancy accurate?

Many women choose to use pregnancy test sticks to check themselves when they suspect they may be pregnant. Pregnancy test sticks are tested through urine and are generally not accurate. In the hospital, you can determine whether you are pregnant early by testing the HCG level in the blood. This test result is more accurate and can usually be detected about ten days after conception. It can also check whether the progesterone level is normal.

Is the blood test accurate for pregnancy?

1. Pregnancy test is the most concerned issue for women when preparing for pregnancy. Once conception is successful, the fertilized egg will continue to produce cell division and secrete a hormone called HCG (chorionic chorionic hormone). The HCG hormone enters the mother's blood, and whether the pregnancy is confirmed can be determined from the blood test.

2. The accuracy of blood pregnancy test is extremely high, close to 100%. Blood test can not only detect whether the pregnancy is present, but also help doctors determine the development of the fetus and the physical condition of the pregnant woman. For example, it can detect multiple pregnancies, hydatidiform moles, ectopic pregnancies, etc.

3. The accuracy of urine pregnancy test is not as accurate as blood test. After all, blood test directly considers the concentration of HCG, while urine test only measures whether it contains a specific value of HCG. Urine test results may be inaccurate due to various physical reasons. However, blood tests are more sensitive than urine tests and are usually done 7-12 days after conception.

Pregnancy test methods and blood test pregnancy time

1. The commonly used method of pregnancy test is to test urine with pregnancy test reagent. Another method is to draw blood for test, commonly known as blood test.

2. Blood tests are generally done for women with special problems, such as infertility or when a problem is suspected. The time requirement for blood pregnancy testing is also very high, generally 7-12 days after conception. The earlier the test is done, the more accurate the results will be.

3. You don’t need to be on an empty stomach or prepare too much when taking a blood test to see if you are pregnant. Because the blood pregnancy test is to check the HCG content in the venous blood, whether you have eaten or drunk water before the test will not have much impact on the test results.

4. Before the blood test, you should pay attention to adjusting your mood, keep yourself relaxed and in a good mood, and avoid tension and anxiety. You should also maintain a reasonable work and rest schedule and avoid staying up late for consecutive nights, so as to avoid inaccurate test results.

What does a blood test for early pregnancy test test?

There are many ways to check for early pregnancy now, but the hospital will definitely conduct a blood test because the blood test can check whether the content of certain substances in the pregnant woman's body is within the normal range. If women only rely on pregnancy test sticks, they will not know the specific conditions of their bodies. The principle of pregnancy test sticks is to check whether the HCG content in urine exceeds a certain value. Blood tests for early pregnancy can not only check the specific content of HCG in the blood, but also check the content of progesterone in women's blood.

Blood tests for progesterone are very important. Many women are at risk of miscarriage if they have low progesterone levels in the early stages of pregnancy. The results of blood tests are also more accurate. Doctors will give women certain advice based on the examination results, and may perform fetal preservation if necessary. This is very important for the baby's growth and can also help pregnant women safely through the early stages of pregnancy.
