You could just ask to draw blood a day or two before the appointment.

That way your doctors would have the results when they see you, instead

of days after.

The snapshot cortisol test is time sensitive, but the response to ACTH

should be about the same throughout the day. It is an artificially

induced response. The snapshot only detects gross anomalies. A more

sensitive approach is 24 hour urine collection. The ACTH tests the

adrenal response, so it is a good detector of adrenal exhaustion.

My doctor has a lab too, and I told him I preferred to go to the one I always go

to because I have bad veins and those particular people know how not to cause

phlebitis with me. There was no argument about times.

 

I went to an endo last year on someone's recommendation, and he insisted that I

have a thyroid panel right there and then, even though I told him I had had a

dose of T3 about an hour before. Well, no surprise to me, the test came out with

the T3 showing high, and he decided he wanted to lower my dose and add T4. I

allowed him to try it (even though it had been tried before), and I got sick

again. I will not do this anymore.
