Blood tests have come back with slightly elevated total calcium levels: 10.3-11 mg/dl. over 3 months. pth was tested but without calcium with a value of 36pg/ml. ionized calcium was 5.1. could this be parathyroidism? ive had joint pain for months to?

According to LabCorp reference range (all laboratories use different ones), normal PTH level is 15-65 pg/mL. Corrected calcium needs to be calculated using a formula accounting for either protein or albumin because calcium is a positively charged anion that binds to them. There are other causes of hypercalcemia that the ordering provide needs to take into account.

It’s possible to have hyper parathyroidism with a normal PTH however, this is rare. Consult endocrinologist for specific diagnosis and treatment.
