• Reference Range:
  

  Male 3 years and older: 0.0-7.5 pg/mL
  Female 3 years and older: 0.0-5.1 pg/mL

  Interpretive Data:
  Calcitonin levels greater than 100 pg/mL may occur in the following conditions: medullary thyroid carcinomas (MTC), leukemias, and myeloproliferative disorders.

  Provocative testing (calcium) is suggested in patients with MTC if the calcitonin is not clearly diagnostic.

  The Siemens Immulite® 2000 method is used. Results obtained with different assay methods or kits cannot be used interchangeably. Calcitonin is useful in monitoring medullary thyroid carcinoma. The calcitonin assay value, regardless of level, should not be interpreted as absolute evidence of the presence or absence of malignant disease.
