    5. Study Description

    Brief Summary
    OBJECTIVES: Determine the relationship between serum calcium concentrations and parathyroid hormone secretion in patients with pseudohypoparathyroidism.
    Detailed Description
    PROTOCOL OUTLINE: Patients are tested for parathyroid hormone response following sequential graded intravenous infusions of sodium citrate and calcium gluconate. Assays include ionized calcium and intact parathyroid hormone.
