I just had mine today – the radioactive uptake iodine thyroid test – not sure if I have those words in order! – But, it wasn’t too bad. About an hour after I took the two capsuls – my throat felt like it was swelling up a bit – but my thyroid is kinda enlarged anyway. And – six hours later – was the scan itself – & it took about 15 minutes. I asked questions – like were there any nodules, etc. But, the last part of the scan is tomorrow morning – & then it’s done.
The tech told me that the dr. will gage the medication dosage upon the results of the scan.
