It is best to go on an empty stomach for the first blood test to check for pregnancy, which may involve other blood tests in addition to confirming early pregnancy.
The first checkup after pregnancy is very important and has more items, including blood HCG and obstetrics and gynecology ultrasound. After confirming early pregnancy in the uterus, it may also be necessary to complete the tests for estrogen, progesterone, liver and kidney function, thyroid function, and blood sugar.
Among them, liver and kidney function and blood sugar must be checked in fasting state, while the results of the remaining items are more accurate in fasting state. However, if the patient is weak, there is no need to force the patient to attend the clinic on an empty stomach.
Therefore, for the first blood test for pregnancy, it is recommended that the patient fasts, completes the relevant examinations, detects abnormalities as early as possible, and receives regular treatment under the guidance of the doctor as soon as possible.
