@za400 My mom had high blood calcium (hypercalcemia) and it was caused by a problem the parathyroid glands. There are 4 of them in the neck near the thyroid just under the skin. When the bad one was removed, her calcium levels returned to normal. It causes calcium to be removed from bones, and a week after her surgery my mom fell and broke her pelvis, and a bone in her foot.
Here is a Mayo link that discusses this type of issue. They do test blood calcium levels while the patient is on the operating table to determine if the faulty gland has been removed. If levels are still high, they look for another bad one. It was an easy surgery for my elderly mom.

Hello @za400 and welcome to Mayo Clinic Connect. I understand your recent blood work has resulted in a request for your doctor wanting to retest.
@jenniferhunter has responded with some great information I will let you review.
Have you had any health concerns leading up to this blood work appointment or was this done during an annual check?
@za400
My regular blood work showed an increase from 10.2 to 10.3 in t he calcium in my blood. My primary care seems concerned and wants to retest me. Any thoughts
