Rarely, people will have normal TSH levels but low T4 levels. This combination suggests secondary hypothyroidism, a condition where thyroid function is impaired due to problems in the pituitary gland.

Dr. Hema Suggests...

Take a Apollo Vitamin Check - Essential Test or Take a ALLERGY ANIMAL PANEL Test
