Guest guest Posted March 24, 2010 Report Share Posted March 24, 2010 The reverse T3 test does not require fasting to be accurate. I get some of my labs from directlabs.com; I wrote and asked them. I have pasted in the text from the emails below. I do not know whether or not the test's accuracy will be affected by his taking thyroid medicine the morning of the test. ----Original Message----- Sent: Wednesday, March 24, 2010 10:31 AM To: contact@...
