I've recently had 11 kidney stones, one 8 mm and the others about 4 mm. Urine and blood studies were done and my calcium level was normal, but my PTH level was 108. Can you have primary hyperparathyroidism if the calcium level is normal, or is that level indicative of secondary? I had a scan yesterday and am awaiting the results. I'm hoping it's primary, because it seems this is easily fixed with the removal of the glands. Thank you.
