*lol* But it doesn't usually happen so early in the day, huh?
The 'rules' for testing are eight hours prior to your tests do not take your meds if: - you are taking Synthroid (or any other T4-only med) and you are having your FT4 tested. It will skew your FreeT4 test and possibly your TSH, but not Total T4, Free T3, Total T3, or T3 Uptake.
- you are taking Armour (or any combination of T3 and T4) and you are having your Free T3 and Free T4 tested. It will skew your FT3/FT4 and possibly your TSH but shouldn't have an effect on Total T3, Total T4, or T3 Uptake.
- you are taking Cytomel and you are having your FT3 tested. It will skew your FreeT3 test and possibly your TSH, but not Total T3, Free T4, Total T4 or T3 Uptake.
YMMV, some of us metabolize slower than others, so the effects might still be felt for more than 8 hours later.
