This shows that nearly 40% of all patients with PRIMARY hyperparathyroidism have Vitamin D-25 levels that are below 20 ng/ml. 60% have vitamin D levels above 20, but that includes 29% who have levels between 20 and 30, which is considered deficient. Nobody with a parathyroid tumor has high Vitamin D-25 levels.
84% of all patients with primary hyperparathyroidism will have LOW Vitamin D-25 Levels! This is 8,397 patients out of 10,000 in our study. 3812 patients (38%) had levels below 20 ng/ml with an average Vitamin D level of 14.6. A more recent study by our group in 25,000 patients showed 92% of patients with a parathyroid tumor and primary hyperparathyroidism have low Vitamin D-25.
