My husband has recently had an NHS Thyroid function test as routine for his Lupus check. They state it's normal but I am not sure about his TSH level. Advice/thoughts would be gratefully recieved.
T4: 17 pmol/L Norm Range: 10-25
TSH: 0.71 mU/L Norm Range: 0.55-4.78
Is the TSH as it should be? I thought it should be really low? They wouldn't test his T3 so encouraging him to have it done privately.
