what are normal readings for TSH & T4
Good question, it depends which lab you have your bloods taken, however i feel that there is no normal readings as everybodies different, TSH should be at 2 to feel well, not sure about t4. you can google your hospitall for lab ranges in your area.
somebody else with be a bit more detailed than me. x
Agree with Merissa - eveyone is different I feel well with my TSH <0.02, mid range FT4 and top quarter of the range FT3, this is on Armour rather than thyroxine (as thyroxine did not agree with me). On thyroxine people often feel well with TSH less than 1 and top of the range FT4 and FT3. xx
Aye, there's the rub.
The right range is in hot dispute and even what to test is in dispute. There is no national range adopted by the NHS.
THE BTA say TSH should be 0.5 to 4.5 mIU/L. if you are in that range you are not ill.
Others say that range should be reduced to 0.5 to 2.0 or 2.5 or 3.0 mIU/L depending on which research you read
Others say that if you have a TSH above 2.0 and have signs and symptoms treat the patient
Others say if you have signs and symptoms, treat the patient and monitor TSH T4 and T3 and look for signs and symptoms of thyroxine poisoning,
Wot are the signs of thyroxine poisoning??????????

Thyroid hormone is critical to normal function of cells. In excess, it both overstimulates metabolism and exacerbates the effect of the sympathetic nervous system, causing "speeding up" of various body systems and symptoms resembling an overdose of epinephrine (adrenaline). These include fast heart beat and symptoms of palpitations, nervous system tremor such as of the hands and anxiety symptoms, digestive system hypermotility, unintended weight loss, and (in "lipid panel" blood tests) a lower and sometimes unusually low serum cholesterol.
Major clinical signs include weight loss (often accompanied by an increased appetite), anxiety, intolerance to heat, hair loss, muscle aches, weakness, fatigue, hyperactivity, irritability, hypoglycemia[citation needed], apathy, polyuria, polydipsia, delirium, tremor, and sweating. In addition, patients may present with a variety of symptoms such as palpitations and arrhythmias (the notable ones being atrial fibrillation),
