My son is 2 years old and was recently referred to a Pediatric Endocrinologist due to slow growth, frequent low grade fevers, and slow growth. His pediatrician ran some basic thyroid levels where his T4 was slightly elevated and TSH was in the low normal range. In talking with the endocrinologist, she expressed that she thought most likely it was lab errors that impacted his thyroid levels and did not really feel he has a thyroid condition. His basic thyroid levels came back in the normal range but we are waiting on the antibody levels to rule out Hashimotos. In the meantime, she wants him to have an ultrasound of his thyroid because she said it was difficult to feel his thyroid and she wasn't sure if she felt it or how the size of his thyroid is. Due to difficulties getting off work and financial issues, it will be very difficult to get the ultrasound done by the end of the year (when insurance changes). Do you feel it is necessary for a thyroid ultrasound if the other labs come back in the normal range? Could there be a problem with his thyroid size that would not result in abnormal thyroid levels? Thanks for your help!
