Hi - We have a 3 week old baby boy and in his PKU tests the thyroid levels were low. So his pediatrician ordered for further tests and below is what the results came out to be:
T4 - 2.8 (Ref Range: 5.6 - 14.4 mcg/dl)
Free T4 - 1.02 (Ref Range: 0.65 - 2.30 nanogram/dl)
TSH - 2.540 (Ref Range: 0.400 - 7.590 microlU/ml)
So Free T4 and TSH seem within range, but T4 is low.
His pediatrician thinks it's okay and nothing to worry about at this point and that we'll continue to monitor and run some more tests in a month. We are just concerned as parents on what the issue could be and if there is anything we should or shouldn't do. Any help/insight would be appreciated.
