This allows Healthcare Providers to get a clear picture of certain substances in your blood or other body fluids, without the interference of food or drink.
Why is Fasting Necessary?
Fasting is necessary for certain laboratory tests because food and drink can affect the levels of substances in your blood. For example, eating a meal high in fat can affect cholesterol levels in your blood, while drinking sugary beverages can affect glucose levels. By Fasting before these tests, Healthcare Providers can get a more accurate picture of your baseline levels of these substances.
