First blood test since adding T3

Hello All.

I'm due a blood test next Wednesday and want the T3 and T4 results to be as accurate as possible - my dr's not concerned about TSH. I take T3 and T4 together when I get up during the night to go to the bathroom, usually between 3 and 4 a.m. Obviously I will not be taking meds that morning, but that will mean that it will have been around 28 hours since my last dose. I think that is too long and I won't get the accurate result that I'm looking for. Am I right in thinking that the time between dose and test is different for T3 and T4? Any suggestions please as to how I can reduce the gap between taking my meds and the blood test, which will be around 8.30am. Thank you.

  • Leabrook,

    Perhaps you could take T3 and T4 earlier, say around midnight.

  • Thanks Clutter . I could do that if you think about 8 1/2 hours is enough.
