Hello everyone. So I will be seeing another doctor for hypothyroidism . However, I realized I gave an incomplete lab test the last time I posted. These are the results:-

Report: T-4(FREE)

Result: 1.11

Ref range: 0.80-1.80 ng/dL

Status: final

Report: TSH

Result: 3.771

Ref range: 0.35-4.940 uIU/mL

Status: final

Please what does the lab tests mean?

Shows you are under medicated and need 25mcg dose increase in levothyroxine

Bloods should be retested 6-8 weeks after each dose increase

Always test as early as possible in morning before eating or drinking anything other than water and last dose levothyroxine 24 hours before test

Likely to need at least another 25mcg dose increase after this too. Unless very petite, most people need at least 100mcg levothyroxine daily

Thanks for the reply. My new physician said we should wait and see. But I am on more vitamin D supplements.

Not what you're looking for?
