Frequently Asked Questions

What are the fasting instructions for a fasting bloodwork?

For routine annual exam blood work, patients can come in without fasting, but it is very important to tell us if you have eaten. The food intake prior to blood tests should be very modest and not greasy or over-sugared.

Eating affects blood sugar, but if we know you have eaten, we can adjust for that. Blood draw after eating does not affect cholesterol levels, but does give us a better idea of your level of triglycerides (blood fats)

Some tests must be fasting, which means no food of any kind. If fasting, you should take lots of water and any medicines you are on.
