Dr. Tran Minh Thao, Deputy Head of the Department of Examination and Treatment on Demand, Bach Mai Hospital, said that there are 7 blood tests that do not require fasting.
- Blood type test: This is a test to determine your blood type. Blood types are usually determined by genetics and will not change. Therefore, you do not need to fast before the test.
- Blood test: Eating and drinking will not affect the test results, so you do not need to fast before taking the sample. However, in the case of blood samples for biochemical tests, immunological tests,... or some other tests, it is mandatory to fast for 8 - 12 hours to avoid distorting the test results.
- Test for hepatitis A, B, C...
- Test for HIV and sexually transmitted diseases such as gonorrhea, syphilis...
- Cancer screening: Tests to find cancer markers such as hormones or special proteins.
- Obstetric-related tests such as Beta hCG quantification, tests related to fetal malformation screening. NIPT test: This is a non-invasive fetal malformation screening method and is chosen by many pregnant mothers. For this test, pregnant mothers can eat a full meal before the test to avoid the risk of hypotension due to hunger.
- Worm test: This is a test that does not require you to fast before the test.
To ensure accurate results for non-fasting blood tests, you should note:
- Although you do not need to fast, you should avoid spicy foods and stimulants that can affect test results.
- You can drink water before the blood test.
- Do not chew gum or exercise before taking the sample: This will speed up the digestion process and may distort the results.
Tests that require fasting before being performed:
Liver function; Kidney function; Blood sugar; Blood lipids; Iron quantification; Platelet aggregation test
The minimum fasting time should be 8-12 hours. Because nutrients will be converted into glucose, then absorbed by the body and converted into energy. At this time, the content of components in the blood will change and distort the test results.
