Do you skip your thyroid meds on lab days?

[TamraW]

I went for my labwork today. Hopefully, I will get my meds raised because I still feel hypo.

My endo's nurse told me not to take my Synthroid before my lab this morning. I thought that was weird, but I took my Synthroid after labwork.

The lab tech said that I would not get an accurate reading.  Should it make that big of a difference since I have been consistend with my Synthroid for the past three months?

Any thoughts?

Thanks!

I don't take mine until after labs either!

I had a bottle of water and my Synthroid in my purse. After bloodwork, I took it out and the lab tech said I should have taken it before the bloodwork. What does he know????

I'm sure glad I listened to my new endo's nurse. The last endo said nothing about this and my TSH measured 1.2. She was afraid to push my meds, even though I felt VERY hypo. She was the doc who treated TSH, not the frees, so she was CLUELESS anyway. I now wonder if my TSH had dropped because of the Synthroid I'd just taken.

I did ask my general Doctor because I forgot to ask the Endo. He said unless I get my synthoid put in an IV directly in my blood stream it does not matter if I take it before the blood draw. Now that I'm on Nature throid I do wait until after. I would listen to the girls on the forum they know more than most Doctors!!!

I do the same as Laura and Deb -- take my T4 med right after the blood draw.  I'm also on cytomel, so absolutely don't want THAT dosage in my system BEFORE the test.....I take a bottle of water to drink with my med and I also take along my coffee mug -- that 30 minutes goes faster than you think..........

My doctors have not told me anything either -- it's just a habit from years of having other types of blood work -- they always say not to take med before fasting blood work......except heart/blood pressure med.

Why dont all doctors inform you of this:( my last blood showed i was a little high in T4....20.7- range (10.0-19.0) said do you feel hyper, as i didn't he said it was prob because i had my meds an hour before i went, he still didn't say dont take it before you come..

I do the same as Laura.
I take my T4 with me but dont take it until blood is drawn.
I usually take a bottle of water with me and take the T4 med in the waiting room After bloods drawn.
By then I am usually 'hanging out' for the T4 med lol.
