Indicator Explainer
Calcitonin
Calcitonin (32 aa, ~3 kDa) is encoded by the human CALCA gene. This protein is involved in the modulation of blood calcium and phosphate concentrations through promoting incorporation of these ions into bone.
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.
