It depends: Are you taking thyroid medication? On any other meds? Why was this test done? Have you been told a bout having a thyroid disease? The TSH level in your case is low....Suggesting a possible hyperactive thyroid state.. This could be a lab error as well. Would check with your doc.. ...Read more

My t3 (liothyronine) is low' but TSH and t4 are normal levels.  I was told not to worry about it unless I show signs of hypothyroidism what are signs of hypothyroidism

More complicated...: There are many signs and symptoms of hypothyroidism, including fatigue, weight gain, constipation, cold intolerance, depression & more. Total T3 (liothyronine) changes with time in the menstrual cycle & as one enters menopause. FT3 (liothyronine) is better lab, but labs not as accurate as for FT4/T4. T3 (liothyronine) & Free T3 (liothyronine) can go down with other illness you have like depression & asthma if sig. Replacement is not rec & controversial. ...Read more

Normal range but,,,: The TSH and T4 and t3 (liothyronine) are in normal range but TSH is low normal and T4 is fairly high normal depending on the reference ranges. A free T4 would help also. You've got fatigue, etc. Which is more like hypothyroidism but it might be from another reason. You apparently don't have symptoms of hyperthyroidism like anxiety and difficulty sleeping, so it'd be smart to see your doctor to be sure. ...Read more

My TSH 3rd generation level came back at 9.490. MY T4 was normal and T3 (liothyronine) was low.Taking 200 mcg. What do these numbers mean?

Still hypothyroid: Not sure how long u have been on thyroid replacement, but if been on 200mcg daily over 6-8 weeks, likely require increase dose. If u have just had u'r medication adjusted the. Repeat TSH usually done in 6 wks; the numbers show that u'r body is still in hypothyroid state and that u'r thyroid gland is making less and less hormone or the T4 is not being converted to T3, (liothyronine) so thyroid medicine needed ...Read more

Check antibodies: Ask your doctor for a test called thyroid peroxidase antibodies. If it's high or positive, then you have autoimmune thyroid disease and will need thyroid replacement in the future, if not now depending on how you feel. ...Read more
