Do I need to fast when I go to the hospital for a blood test for pregnancy?

We all know that many blood tests are often required to fast in order to ensure the accuracy of the test results. So for the special group of pregnant women, do they need to fast when going to the hospital for a blood test for pregnancy? In fact, many tests during the prenatal check-up period also require fasting, but it is not necessary to go for a blood test to confirm whether you are pregnant.

Do I need to be on an empty stomach when I go to the hospital for a blood test for pregnancy?

This is not a liver function test or a blood sugar test, but a blood test for HCG, so you don't need to fast. But some doctors say that fasting should be more accurate, because the index values ​​in the blood after a meal are not exactly the same as those on an empty stomach, but if you have already eaten, you can also check it, so you don't necessarily need to fast. Theoretically, if you are pregnant on the 9th day of ovulation, which is the 23rd day of menstruation, you can use a more sensitive method to detect whether you are pregnant. In order to confirm whether you are pregnant or not, you can choose a pregnancy test.

Pregnancy tests use the molecular biology or medical immunology characteristics of human chorionic gonadotropin in the urine and blood cells of pregnant women to detect whether the body contains human chorionic gonadotropin. A positive test result indicates that the urine human chorionic gonadotropin is at least 25u/L. In clinical medicine, pregnancy can usually be detected through this bridge a few days after menstruation. However, the pregnancy test paper can only determine whether there is pregnancy but not the location of pregnancy. This is especially true for pregnant women with irregular vaginal bleeding. If the pregnancy test paper is positive, they must consider the possibility of ectopic pregnancy, also known as ectopic pregnancy, and even other pregnancy-related diseases, such as the possibility of trophoblastic disease. Both of these conditions seriously affect the physical and mental health of pregnant women.

How long does it take for the hcg blood test to produce results?

After the menstruation is delayed, you can draw blood to check hCG to confirm whether you are pregnant. The charge in each area is different, about 50 yuan, but there are fast and slow ones. The fast one takes two hours to get the result and costs 60 yuan, while the slow one takes about 6 hours to get the result, which costs about 40 yuan. It is recommended that you go for a check-up immediately. The cost will not exceed 100 yuan. The blood test is more accurate than the pregnancy test paper and can know whether you are pregnant earlier.
