A blood test is a test in which a sample of your blood is drawn for testing in the laboratory.
Usually, no special preparation is required for most of the blood tests. Few blood tests may require fasting for 8 to 12 hours before the blood draw. It means you don’t eat or drink anything, except for water during that time frame.
