Guest guest Posted December 1, 2010 Report Share Posted December 1, 2010 I think it's most important that you always do it the same way so that the labs can be compared apples to apples instead of apples to chairs. IMO, your doctor's preference should be respected, probably for this reason. My preference is to have an early fasting blood test and take any and all morning meds afterward.

Guest guest Posted December 1, 2010 Report Share Posted December 1, 2010 I strongly recommend you do the testing prior to taking your thyroid in the morning. I spent the most miserable year of my life because i had an idiot doctor that didn't understand the impact of my having taken my thyroid prior to testing. My T3 was well over range and the doctor decreased my dosage to a very miserable level. Once I got educated and started doing the labs before taking my thyroid, reality hit and it was clear I was way under medicated. It's really impossible for you to know exactly how your body is metabolizing the T3 unless you do several blood tests during the 4-6 hour time period. Based upon how I feel, I believe my T3 peaks far sooner than 4 hours . So, I personally would follow the nurse's suggestion. There are doctors purported to be able to extrapolate in cases where you have taken your dosage, but I think that is quite rare. B. Hi Everyone! I need some advice, if anyone is around to answer. I'm on WEEK 8 of 1 grain Armour Thyroid, split twice daily. It is time for a lab draw, and doctor said I can either test without morning split, or with it, either way. My labs from September show I'm low FT3, FT4 is mid-range. I'm wondering if I take labs with no Armour, will it show me if my incoming T4 is converting to T3 now...? I have learned that FT3 stays active in the body about 5 hours, and it would be wise to take split morning dose, then test about 4 to 5 1/2 hours later and would show me where I'm falling in the range. The nurse said the doctor prefers to test with no Armour, but since they gave me the option, now I'm wondering what to do? Hubby off so can watch kids if I decide to do it today. Thoughts anyone? Prior labs:------------------------------------------------------ Free T4 1.21 Range .73-1.95 TSH 2.3 Range 0.3-5.1 Free T3 2.8 Range 2.3-4.2 Thyroid Peroxidase AB <10 Range <35 Thyroglobulin AB <20 Range <40 Thanks in advance for your help. I appreciate the wisdom from this group! I had a great advocate on another site, but she has retired for now...being a thyroid advocate is hard work!
