I have been running a high serum calcium level for several years now. I have had the following reading
on serum calcium
from 2007 to 2009. 10.5, 12.9, 10.9, 10.7, 11.0, 11.4, 10.6. I have had one PTH level done about a week ago and it was 46. I just had an ionized calcium level done and it was 5.7. I had a parathyroid ultrasound done last week and it did not show any parathyroid problems. I had a chest xray done and a test for sarcoidosis, it was negative.
