Her Doctor has answe: This Calcium level is clearly abnormal. Besides cancer, there are some benign causes of High Calcium,one being Hyper-Parathyroidism which is often caused by a benign adenoma of the parathyroid gland. An endocrinologist can help her to sort out the cause.

May have no CA: 15 to 65 pq / mL. is the range of parathormone in the serum. The only question is the slightly elevated bone calcium which might be associated with bone mets. This should show up on the scan. When parathormone is elevated it is usually derived from the parathyroid glands which might be hyperplastic or have a tumor. Occassionally an elevated parathormone level is seen in myeloma.
