I'm worried because,it's crucial that the blood test show the doctors there is something wrong with me and it needs to be documented.I worry that a 3 hour fast isn't long enough.Does anyone know if it is?
The reason they do the 3 hour fast is because for people with blood sugar problems, it can be dangerous for them not to eat anything for so long. The lab test is designed to test accurately on a 3 hour fast so there isn't a reason to go longer, especially at risk to your health.
