I have been taking Armour 1 grain for 2.5 months now. Previously on Levothyroxine 100gms. First blood test after starting on NDT gave strange results. Please see below. I have put previous test whilst on Levo in brackets.
Vit D - 61.5 nmol/L (68.3) - 50-175
TSH - 1.82 mIU/L (0.065) 0.27-4.2
Free T3 - 3.57 pmol/L ( 5.11) 3.1-6.8
T4 - 8.0 pmol/L (19.6) 12-22
Thyroglobulin Antibodies - 409.0 kIU/L (450) <115
Thanks in advance to all you knowledge people out there!

Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .
If/when on NDT make sure to take last half or third of daily dose 8-12 hours prior to test, even if this means adjusting time or splitting of dose day before test
Hello SlowDragon thanks for your reply. Yes I do fasting and had at least 12 hours from last dose to Test. The reason for my query was how can both T3 and T4 go down - particularly T4 was a huge decrease but there was not a corresponding increase in T3 as I thought might happen after starting NDT.
Having Hashi's can make your levels jump around. These latest results are more likely to be accurate than the previous set. You are under-medicated on one grain, as might be expected. Plus it sounds like you left too long between your last dose of NDT and the blood test, which would go some way to explain the low FT3,
