--might pick up enlarged parathyroid glands; the ultrasound technician would probably have to be looking for them, though, as they are normally very small (about the size of large rice grains).

I suspect that noticing them may depend on the skill and training of the technician, as well. I have my scans done by an interventional radiologist who I trust completely (and whose three daughters I've tutored); she's also the one who did my thyroid nodule biopsies. (She's obviously very familiar with what's going on in there through the years.) I don't trust this to a non-physician technician.

So, if your albumin is 4.8 your calcium levels are not THAT high--but it wouldn't be a bad idea to get the ionized calcium and parathyroid hormone tests.
