Brief Answer: The TSH report obtained on 23-2-2014 is normal. Detailed Answer: Hi, Thanks and welcome to healthcare magic. About 1: 4000 infants suffer from congenital hypothyroidism. 4% of infants born to mothers bolnging to endemic iodine deficient belt in India have biochemical evidence of hyperthyroidism . Examination of blood ( cord blood or baby's blood ) is done after 3-4 postnatal days. TSH levels more than 50 uiU/ml in cord blood are diagnostic of neonatal hypothyroidism . The present levels seem to be normal. Better repeat the test again . Hope this answer serves your purpose. Please feel free to ask further queries if required. Take care. Dr.M.V.Subrahmanyam.

Hello Doctor, Thanks for your response. Just another question - Baby's mother is already having the Thyroid problem and she takes a Thyonorm 25 tab daily. Is Thyroid problem is hereditary? What are the chances that thyroid problem will be there with Baby also? Is their any defined age when thyroid problem occurs in general?
