Brief Answer:
Likely Sick euthyroid state

Detailed Answer:
Good day,
Noted your concern. A single borderline low TSH while Ft4 is normal is called sick euthyroid state which is very common during a viral illness or a svere stress. However, in the recovery phase, TSH can go up to 15 and then gradually normalise.

Not to worry. Recheck the TSH after 1 month. If it stays below normal, then you may require a Technitium uptake scan ( Nuclear scan) to decide further.

Binu
