Guest guest Posted January 2, 2006 Report Share Posted January 2, 2006 No, for thyroid labs you don't have to fast... but don't take your any thyroid meds that day until AFTER the blood draw.....

Guest guest Posted January 2, 2006 Report Share Posted January 2, 2006 Oh thank you!!! What a blessing to go to the lab at a normal hour and with fuel in my system. I can't fast late into the morning because of issues with low sugar, thus my VERY early up to get to the lab first. Once they see my set of labs that I do each four months (15 vials worth) they tend to shovel me back in the pecking order. If I am one of the first three I can get in right away because I catch them by surprise. haha. Tomorrow I will visit my PCP and request that he add the TSH, Free T4 and Thyroid Antibodies to my current order. He should comply as he is a pretty good guy and won't be surprised at all that I have been researching this over the holiday.

Guest guest Posted January 2, 2006 Report Share Posted January 2, 2006 I'm only 2 months into this all things thyroid and I get to pass on some things I've learned. Thyroid hormone, even in pill form, is stored in the cells of the body as T4. The synthetic med we take is T4 except Cytomel is T3. The body takes T4 and turns it into T3 and uses T3 for running all things, literally, all things. Since what is tested in lab work is what has been stored in the cells, eating or not eating doesn't matter. If you take your med before getting lab work done, there may be a false rise reading as that med is in the process of being incorporated into the storage of it in the cells. Since what is being read in the blood work is what is stored in the cells, eating or not eating doesn't matter. Taking your med before getting lab work done can change the reading some. jane tt 11/7/05 > papca encap; vasc inva 12/5/05 > rai 139 11/25/05 > wbs 12/2/05 normal post tt > levothyroxine 200 12/9/05 From: " Marie " > What if you did have a thyroid lab after fasting?

Guest guest Posted January 5, 2006 Report Share Posted January 5, 2006 No, not fasting, unLESS you are also having other testing done in the same blood draw for blood sugar, etc......This IS a fasting test, unless it is a "random" blood sugar. If your doctor is doing a lot of other blood work at the same time that requires fasting, then you would fast, but this has nothing to do with the thyroid hormone blood work. Fasting for Labs? Is it necessary to do the thyroid labs fasting? TSH, Free T3, Free T4, and Thyroid antibodies, specifically. I have a number of labs that have to be done as fasting labs, but since I will be pursuing labs specifically for evaluating my thyroid I am hoping that I don't have to get up at 5 a.m. to be first in line.
