Medical Service Information
Conditions & Notices
- Fasting for 8-12 hours is required, because eating a fatty meal may temporarily affect blood levels of vitamin A, as it is fat-soluble.
- A standard venous blood sample is drawn.
- Inform your doctor about all dietary supplements and vitamins you are taking, especially vitamin A or beta-carotene supplements.
- Avoid consuming liver or fish liver oil several days before the test if possible, as these are very concentrated sources that may temporarily raise the level.
- Handle the sample carefully because vitamin A is light-sensitive; the tube is usually wrapped in foil.
