Do I Need to Fast Before Taking an Everlywell Test?
When Do I Need To Fast Before Bloodwork?
It is always important to check with your healthcare provider before going in for bloodwork to see if fasting is needed. Certain blood tests require fasting to obtain accurate results. Since they can impact blood sugar levels, it is also vital to avoid gum, smoking, or intense exercise before this test. [1]
Typically, there are a few blood tests in which it can be helpful to fast. Some of these include [1]:
- Blood sugar
- Cholesterol
- Liver function tests
- Renal function tests
While these are some of the most common blood tests for which fasting can be helpful, your healthcare provider may want you to fast before other tests as well. It is best to check with them before testing. Fasting for bloodwork is not needed for many panels.
Why Do Nutrients Affect Test Results?
The reason fasting can be helpful when testing certain lab values is that when you eat or drink calories, the nutrients consumed go into your bloodstream and are temporarily reflected in your blood levels. [2] By avoiding food and drinks that affect the blood sugar, your healthcare provider can get a better idea of what is naturally happening in your blood most often.
Typically, the fasting window is about eight to twelve hours. To make this process easier, you can try scheduling your fasting blood draw first thing in the morning so that the majority of the fast will be overnight.
Plain water does not affect blood levels, so feel free to stay hydrated during your fasting window. It is also essential to check with your provider on their recommendation regarding the continuation of medications. If you are not able to fast or if you forget, it is important to inform your provider.
