Brief Answer:
Please do a repeat TSH and Free T4

Detailed Answer:
Good day,

Noted your question. TSH of 0.06 is definitely low. This need further check ups. Please get a repeat TSH along with a Free T4.
TSH levels can vary in a number of conditions and many a times, a repeat test after few weeks turns out to be normal.

Do you have any neck swellings? Are you on any medications? ( especially steroids)

Regards
Binu

What is normal TSH I have had a low reading for the last 2 or so years

Answered by Dr. Binu Parameswaran Pillai (1 hour later)

Brief Answer:
Free T4 to be checked and based on that, next test should be done

Detailed Answer:
Thank you for the reply. In most labs, normal TSH ranges between 0.3 to 5 mIU/L.

If your TSH is low for a long time, your doctor should ideally order a Free T4. If TSH is low and Free T4 is normal or high, they should request for a Technitium scan ( nuclear scan). On the other hand, if your TSH and an Free T4, both are low, your doctor should order an MRI scan of pituitary.
