Indicator Explainer
Parathyroid Hormone
Parathyroid hormone (115 aa, ~13 kDa) is encoded by the human PTH gene. This protein is involved in the modulation of calcium ion and phosphate concentration in the blood.
This page explains what the indicator is and how results are interpreted in general terms. Reference ranges depend on the laboratory, the method, and your own situation — no single “normal value” applies to everyone. This page is health information, not a diagnosis. For symptoms, treatment, or urgent concerns, contact a healthcare professional.

Reading results
Reference intervals and interpretation depend on the laboratory, specimen, method and clinical context. This source definition is educational information; it does not establish a diagnosis, product approval or suitability for an individual.
