Serum calcium levels out of range ref (10.2) mine were 10.2, 10.5, 10.3 over the past six months. endo did tests and have normal thyroid function w/9 nodules.hetero thyroid, says not primaryhpt, should i check for something else or is this okay?

I wonder if you were tested for ionized calcium, phosphorus, and urine calcium as well. Is there family history of hypercalcemia? If you had normal level of ionized calcium and phosphorus, mildly elevated calcium levels are likely to be insignificant.

All laboratory/imaging results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, your results are not a cause for any immediate concern. Wish you good health!
