Is it necessary to be fasting for blood test before pregnancy?

If a pregnant woman needs a blood test before pregnancy, she must be on an empty stomach. Only in this way can the examination be done well. If she eats and then does the blood test, the result will become inaccurate, or even impossible to continue the examination. Therefore, this is very important, and relevant examinations of the reproductive system are also required.
