So urine Iodine test result shows low iodine 75 (100-199) and I am a couple of years into Hashimotos, had high TPOab antibodies and up down T3/T4 (have had extreme TSH) but recent urine T3/T4 taken at same time as this Iodine urine test the T3 and T4 was back in range (no meds). Not known what TSH and antibodies as not had serum tests lately.
So my question is..... why might iodine be low, is the urine test showing it is a receptor problem or has it been via whatever receptors and hence coming out of body? So simply low? If I supplement, which is apparently a no no with hashimoto...do we guess it will be taken up or will it build up.....I have been trying to read all this time, since diagnosed but so confused as to what to do.
Is there a likelihood that I was lacking in Iodine and that caused antibodies, as that is not what I understood as thought it was auto immune that causes thyroid damage.....? Thanks in anticipation.
