Do you have your FT3 and FT4 results with reference ranges, also? TSH is a screening test at best, and any result even close to being out of range should prompt FT3, FT4 and antibody testing.
Do you have other thyroid symptoms?
In April TSH was 0.3 (range 0.4-4.5) and the Free T4 was 1.0 (range 0.8-1.8). In the hospital 5/21 the TSH was .12 but they didn't do T4 or T3. The labs I had done 5/22 are being sent to me but the doc told me the TSH was 0.04 and the T4 and T3 were "normal". She hadn't gotten the TSH antibodies back yet but labs are complete now so I will know what all those are as soon as the fax comes in. I'm a wreck as this is the 9th day of constant PVC's and the 40 mg of Nadolo (beta blocker) aren't doing a thing. The endo said PVC's could be from adrenaline and I'm doing a 24 hr urine test to check for adrenal probs. I said wouldn't I have a fast hear rate (tachy) too? She said no because of the BB. But if the BB was working to keep the heart rate down why is it not helping the PVCs? I've put a call in to my cardiologist too. But I had a crying jag this morning cuz I'm getting overwhelmed...
got the labs: TSH = 0.04 (0.40-4.50), Free T4 = 1.3 (0.8-1.8) and Free T3 = 3.4 (2.3-4.2), Thyroid Peroxidase Antibodies = 2 (range is <9), Thyroid Stimulating Immunoglobulin = 13 (range <140). So all Thyroid tests are "normal" except the TSH which is very low.
I'm sure that goolarra will be responding to your new lab results. In reading this thread, I remembered seeing some info about palpitations and low magnesium, that I thought you might find interesting.
Thanks. I'll have to look in to that. I take a whole food multi-vitamin/mineral which I'm sure includes Magnesium but maybe not enough. I'll need to ask the cardiologist too.
In case the Cardio is one that tends to ignore such possibilities, you might want to reference this info also.
