You could: By definition, if you have no symptoms, you have sub clinical hypothyroidism because your T4 measurement was (barely) outside of the average normal range. Your body chooses it's T4 set point and uses TSH to increase as needed. Your elevated TSH shows that the thyroid gland needs to be pushed a little harder but it would be much higher if gland was not producing T4. If asymptomatic, don't worry.
