Reference range

Reference ranges are challenge-dependent and interpretation is based on fold-rise or absolute peak calcitonin concentration relative to baseline. Provocative testing (e.g., calcium or pentagastrin stimulation) is primarily used to evaluate medullary thyroid carcinoma (MTC) and C-cell hyperplasia. Consult performing laboratory for assay-specific thresholds.N/A
