A vital diagnostic tool, the PTH-Intact (Parathormone Intact) test evaluates parathyroid function and calcium metabolism. PTH-Intact testing has implications for health heart diagnostics (HHD) despite its major focus on bone health and calcium management. This is because calcium plays a crucial role in cardiovascular physiology.

The parathyroid glands secrete parathormone (PTH), which increases calcium absorption from food, calcium reabsorption from the kidneys, and vitamin D activation to control the body’s calcium and phosphorus levels. PTH levels that are too high or too low can cause serious disruptions to calcium homeostasis, which can have an effect on cardiovascular health. For instance, hypercalcemia, or higher calcium levels, is frequently the result of hyperparathyroidism, or high PTH levels.
