Your question is not complete - by itself, that measurement could mean anything.

How Are Thyroid Problems Diagnosed?
To diagnose a thyroid problem, doctors test your T3 and T4 levels, not your thyroid levels.

Doctors will also test the TSH (Thyroid Stimulating Hormone) and TSHRH (Thyroid Stimulating Releasing Hormone).

What Could 0.15 Refer To?
The levels that you are mentioning seem to apply to the TSH levels. A normal range for TSH levels is between 0.5 and 5.0.

Low TSH levels could mean that the thyroid gland is overactive, or you have hyperthyroidism.

What Are TSH Levels Compared With In Order To Diagnose A Thyroid Problem?
These reduced levels of TSH are then compared with the T4 levels. The decreased TSH levels and increased T4 levels would point to hyperthyroidism, but without knowing more details, I can't give you a definitive answer.
