WebbRemember, the primary controller of PTH is serum calcium. If low calcium diet or vitamin D deficiency lowers serum calcium even slightly, PTH will rise to correct it back. If serum calcium should rise from, as an example, very high vitamin D intake or very high calcium intake, serum PTH will fall to correct it. WebbExposure to air increases the pH of serum, which causes proteins to bind to calcium, resulting in low ionized calcium concentrations.
