A member asked:

My dad is worried because his thyroid stimulating hormone (serum) is high (5.370) but free t4 (serum) is within range (14.80). please explain and help?

A doctor has provided 1 answer

Ranges?: The TSH is slightly high but and free T4 of 14.80 (if that is not an error) is high. You say his free T4 is normal, however if this the case, he may have what we call subclinical hypothyroidism. Further testing may be needed (thyroglobulin antibody, thyroid peroxidase antibody) before any decision to treat can be made.
