  • Normal TSH, low T4 - What is going on? : r Hypothyroidism - Reddit
    TSH is 0 59 and a normal range is listed as 0 3 - 4 7 mcIU mL My free t4 is 7 with a normal range being 0 80 - 1 70 ng dL That is barely off, but I want to start trying to get pregnant soon and I've lost myself in a Google hole and now I'm scared I have a tumor or undiagnosed pituitary issue
  • Low T3, low T4, normal TSH : r Hypothyroidism - Reddit
    He wants me to be off all thyroid medication (I take a low dose that keeps my T4 within normal range but my free T3 is always too low) for 6-8 weeks and retest to re-establish baseline He would do a TRH stimulus test but says TRH is not available for injection in the U S (unsure about that personally), so instead is sending me to Quest to get
  • Low total T3 but normal T4 and TSH : r Hypothyroidism - Reddit

  • What does a normal TSH but low free T4 mean? : r Hypothyroidism - Reddit

  • Normal TSH, Normal Free T3, Borderline low Free T4
    There is more evidence that some people are cellularly hypothyroid even with normal TSH, and the normal range should be lowered to 2 5 or so for most people If you have symptoms with no other reasonable explanation (and you should be tested for other possible causes!) ask for a trial dose of levo
  • Normal TSH, Low T4 Free. 34m : r Hypothyroidism - Reddit
    T4 Free: 0 34 ng dL (0 93 ng dL - 1 70 ng dL range) I don’t know if it’s relevant, but I’m in the military and my doctors are military doctors I sent them a message yesterday about this reading, asking if it was cause for concern and they said: “Good Morning, Even thought your T4 was a little low, your TSH was in the normal range
