Brief Answer: You likely have a slightly overactive thyroid Detailed Answer: Your TSH is low. The free T4 is within normal limits though. Were you taking any steroids like prednisone/hydrocortisone/dexamethasone or opioid pain killers like hydrocodone, at the time this blood sample was taken? Because these agents can lower the TSH without there being a real problem with the thyroid. It only makes the blood test look like that. Similarly, if you were in the hospital under some stressful condition or illness, your thyroid labs can look like that temporarily and it often spontaneously resolves i.e. the blood tests look normal upon retesting a couple month later. However, it is possible you have a slightly over active thyroid too. But this may not necessarily merit treatment right away unless it is causing an irregular heart beat or angina-like chest pains, or osteoporosis. This link describes potential symptoms from this condition: WWW.WWWW.WW A comprehensive work up includes repeat testing for TSH Free T4 total T4 Total T3 T3 resin uptake prolactin (to rule out the rare possibility of a pituitary problem) If this reveals similar results as the first one and you have symptoms suggestive of thyroid overactivity then further tests like the following may be necessary before embarking upon treatment options that include medication, radiation or surgery. Ultrasound of the thyroid Radio iodine uptake and scan
