Is TSH w/reflex to ft4 4.06 normal?

Is TSH w/reflex to ft4 4.06 normal?

High normal: A TSH of 4.06 is in the upper range of normal. The lab probably did not do the ft4 level, since the TSH was normal. Most people with these results feel perfectly normal. However, it could be a sign that your thyroid is starting to fail. It would be reasonable to repeat the TSH and do a free T4 level in a few months. ...Read more

Low free t3, (liothyronine) normal TSH and high tpo antibodies. What's this mean?

RollerCoasterWillEnd: I'd take his suggestion.It's a period of adjustment & you'll need to fiddle with your meds until you find a happy balance.I suspect you won't be off the medication for very long unless they left something in there.But if you start to feel sluggish it's time to contact Mr or Ms Endo.I'm sure you've already arranged follow-up, right??

 thyriod autoantibodies <1.8 thyroperixdiese >15.1 these are my ranges?

Strange: Why were these tests ordered by the doctor? Why did you go to the doctor? Did the doctor take a history and perform a physical exam before sending lab tests? Your TSH and free T4 are normal. Therefore, the function of your thyroid is normal. These antibodies are used to detect Grave's disease or Hashimoto's thyroiditis. Why is your doctor suspecting these diagnoses, when your TFT's are normal? ...Read more

TSH w/reflex to T4 was 0.25. T4 free 1.2. T3 free 2.7. Tsh level was higher and synthroid (thyroxine) 137mg. Still on same dosage. Would this cause fatigue?

TSH w/reflex to T4 was 0.25. T4 free 1.2. T3 free 2.7. Tsh level was higher and synthroid (thyroxine) 137mg. Still on same dosage. Would this cause fatigue?

Possibly.: The low TSH with associated normal free T4 and free T3, (liothyronine) suggests borderline hyperthyroidism (overactive thyroid) which can cause fatigue. However, one should seek a thorough medical exam prior to concluding that the symptom of fatigue is not due to some other problem. ...Read more
