Dear Dr. Lupo:
Does having any detectable thyroid antibodies are of any significance?
I just had a full thyroid panel and wonder if the antibodies results are of any significance:
TSH - 1.54 uIU/mL (0.35 - 4.94)
T4 Total - 8.55 ug/dL (4.87 - 11.72)
T Uptake - 43.3 % (32 - 51)
Free Tiroxine Index - 9.26 ug/dL (5.93 - 13.13)
T3 Total - 1.03 ng/ml (0.58 - 1.59)
T3 Free - 2.90 pg/mL (1.7 - 3.7)
T4 Free - 1.37 ng/dL (0.70 - 1.48)
Thyroglobulin Autoantibodies - 26.6 U/mL (Reference range 0-34)
Thyroid Peroxidase Autoantibodies - 5.5 U/mL (Reference range 0-12).
I was told that sometimes the lab equipment that measures the antibodies will never give you values of zero, but I really don't know.
Thanks and your help is greatly appreciated,
Roberto
