Re: -fasting question for tests

[Guest guest]

I had been going and getting tests for everything but cortisol and told

coffee was OK as long as black. When I started using a lab in FL that was

the main office so ran them there, they said no, because the caffeine spikes

insulin and cortisol which in turn changes thyroid levels. I showed them the

thing from their papers that showed coffee was ok and told them that i had

been drinking coffe before I went. The lab tech two days in a row after that

days test ran tests with and then without coffee. My thyroid free t3 and tsh

were higher with coffee. How is that for strange. I mentioned this back then

on about.com. Many lab techs and a scientist agreed, they would never drink

coffee prior to testing. JMHO from seeing it.

Actually makes good sense, come to think of it, because coffeee does

stimulate the adrenal glands and the cortex of the brain. I suppose that

would stimulate the hypothalamu, in turn stimulating the pituitary, in turn

stimulating the thyroid gland, BUT, what if the gland can't make any more

T3? What then? It would go to reason to me, if the gland can't make it,

then how could it be increased? The cortisol part makes perfect sense.

Makes me wonder, though, thyroid tests have always been nonfasting, so what

other foods could affect this cycle of happenings at testing time, or, for

that matter, any other time?

Aha!

Guess what I'll be drinking the morning of my upcoming thyroid panel?
