Dear Practo User,
Did your wife took the
thyroid pill the day she went for a repeat test??
In that case the report can be falsely normal.
It also depends on how grossly abnormal was 1st report and what dose you are currently taking.
Lab variations can occur but they should be minor. If major , you can go to the lab again and ask them to repeat the analysis.
Next Steps
If no hypothyroid is there, treatment should be stopped and 3mthly follow up for same in case of doubt should be done.
