High pth blood level but normal calcium blood level?

PTH: Low vitamin d or a diet low in calcium can cause PTH elevation in the setting of normal calcium. Also kidney problems can cause a similar process due to difficulties processing vitamin d.

What is the calcium?: Upper normal calcium with high PTH could indicate primary hyperparathyroidism as well. Other possible causes include: low vitamin d, kidney problem or a lab error. You need to sit down with your doctor to look at all values, not just calcium and pth. Good luck.
