According to Dr. Tran Minh Thao, Deputy Head of the Department of On-Demand Medical Examination and Treatment at Bach Mai Hospital, there are 7 blood tests that do not require fasting.

- Blood type test: This test determines your blood type. Blood types are usually determined by genes and do not change. Therefore, you do not need to fast before the test.

- Complete blood count (CBC): Eating and drinking will not affect the test results, so you do not need to fast before sample collection. However, for biochemical tests, immunological tests, or other tests, fasting for 8-12 hours is mandatory to avoid inaccurate results.

- Tests for hepatitis A, B, C...

- HIV testing and testing for sexually transmitted infections such as gonorrhea, syphilis, etc.

- Cancer screening: Tests aimed at detecting cancer markers such as hormones or specific proteins.

- Obstetric-related tests such as Beta hCG quantification and tests related to fetal anomaly screening. NIPT test: This is a non-invasive method for screening fetal anomalies and is chosen by many pregnant women. For this test, pregnant women can eat a full meal beforehand to avoid the risk of low blood pressure due to hunger.

- Parasite testing: This type of test does not require fasting beforehand.

To ensure accurate results for blood tests that do not require fasting, please note the following:

- While fasting isn't required, you should avoid spicy foods and stimulants that could affect the test results.

- You can drink plain water before a blood test.

- Avoid chewing gum and exercising before sample collection: This will speed up digestion and may skew the results.

These tests require fasting beforehand:

Liver function; Kidney function; Blood glucose; Blood lipids; Iron levels; Platelet aggregation test

The minimum fasting time should be 8-12 hours. This is because nutrients will be converted into glucose, which is then absorbed by the body and converted into energy. During this time, the levels of components in the blood will change and skew test results.
