INTACT PTH-PARA THYROID HORMONE (PTH)

Overview

The Intact PTH test measures levels of parathyroid hormone (PTH), which is secreted by the parathyroid glands to regulate calcium and phosphorus balance. Elevated PTH levels are common in primary hyperparathyroidism, though some patients may present with normal levels despite high calcium. The test helps diagnose calcium-related disorders and assess parathyroid function, with low serum phosphorus often accompanying elevated PTH.
