Whether pregnant women need to fast for blood tests depends on the items that need to be examined. Fasting is required for blood tests such as fasting blood glucose, liver function, kidney function, etc. Fasting is not required for blood tests such as progesterone and chorionic gonadotropin.
If a pregnant woman has her blood drawn for fasting blood glucose, liver function, kidney function, thyroid function and other tests, it is recommended that she fasts before the test in order to avoid the test results being affected by dietary factors. If the blood test progesterone, chorionic gonadotropin, estradiol, etc., the results of the test will not be affected by the food, it is possible not to fasting test.
Prenatal checkups for pregnant women are good for preventing and treating pregnancy complications, as well as detecting fetal abnormalities in a timely manner. Pregnant women are advised to know what tests they need to do and ask the doctor in advance whether they need to fast before the test, so as not to affect the test results.
