Hi,
I just had an i123 uptake scan and the results were 9.5% after 4.5 hours and 21.5% after 24 hours. I am not sure if there were any hot or cold spots. I looked at the machine when we were done so that is why I know the uptake percentages. I do not know what the normal ranges are for my lab here in CA. Does anyone know what is considered normal? I have had several low tsh readings but only slightly under normal, all other thyroid labs have been on the low end of normal incl. antibody tests and ultrasound was normal with slight heterogeneity. I have symptoms of hyper incl. rapid heart rate, anxiousness, lack of concentration, etc. I have also had a positive ANA with a homogeneous pattern, however, again my titer was slightly below normal 1:160. < 1: 140 abnormal for my lab.
Thanks.
