Response to Comment: Frequency of hypothyroidism in Patients with β-thalassemia

Madam, reference to my article titled Frequency of Hypothyroidism in patients of β-Thalassemia published in the January 2010 issue of JPMA. Thank you for the feedback. As regards the comments: Tests for serum ferritin levels in the our patient population were repeated every few months or so. The values we recorded were those measured within the last 6 months from the time of sample collection.
