You should fast before tests. It works for me.
It all depends on what sort of test you are undergoing. with some tests it is required yet with other tests you should eat as you would normally to get the correct results, then again with some it makes no difference one way or the other.

Do you need to fast for BUN and Creatinine lab test?
Most of the time, you don’t need to fast before a BUN (Blood Urea Nitrogen) or creatinine test. These tests check how well your kidneys are working, and you can usually get them done whenever it fits your schedule. But sometimes, your doctor might want you to fast for a few hours. It may be because you’re getting other blood tests, like a glucose test or a lipid panel, you’re having a full metabolic panel, or the lab has its own set of rules. One more thing: drink water like you usually do, unless your doctor tells you not to. If you get dehydrated, it can mess with your BUN and creatinine results. When in doubt, just go with whatever instructions your doctor or the lab gave you before the test. That’s always your best bet.
