PTH, Intact without Calcium
PTH (parathyroid hormone) regulates calcium and phosphate balance in your body. This test checks if your parathyroid glands are functioning normally without requiring a simultaneous calcium measurement, making it useful for screening thyroid/parathyroid disorders, investigating bone health, or monitoring kidney function.
PTH indirectly affects bone density, muscle function, and electrolyte balance—all relevant to athletic performance and injury prevention. Abnormal PTH can signal calcium metabolism issues that compromise bone strength or muscle contraction efficiency, though this test is not routinely used for athletic performance optimization. It's more relevant for identifying underlying metabolic problems that could impair training capacity or recovery.
