    Summary
    This summary is machine-generated.

    Normal human calcitonin levels were established using radioimmunoassay in 256 individuals. Calcitonin levels vary by age and sex, with no correlation to bone atrophy.

    Area of Science:

    • Endocrinology
    • Biochemistry
    • Clinical Chemistry

    Context:

    • Radioimmunoassay (RIA) for human calcitonin established in 1969.
    • Previous reports have not definitively ascertained normal calcitonin values.
    • Calcitonin plays a role in calcium homeostasis and bone metabolism.

    Purpose:

    • To establish normal reference ranges for serum calcitonin in healthy individuals.
    • To investigate the influence of age and sex on calcitonin levels.
    • To explore potential correlations between calcitonin levels and bone atrophy.

    Summary:

    • Serum calcitonin was measured in 256 healthy individuals using radioimmunoassay.
    • Normal calcitonin values ranged from <10 to 249 pg/ml (average 49.0 pg/ml).
    • Calcitonin levels peaked in the third decade, declining thereafter, with sex-specific variations observed across different age groups.

    Impact:

    • Provides essential reference ranges for interpreting calcitonin levels in clinical settings.
    • Highlights age and sex as significant demographic factors influencing calcitonin concentrations.
    • Findings indicate no direct relationship between calcitonin levels and bone atrophy, suggesting calcitonin's role may not be primarily linked to bone density in healthy individuals.
