Calcitonin (Thyrocalcitonin), Eight Specimens
Use
The Calcitonin (Thyrocalcitonin), Eight Specimens test is utilized for assessing calcitonin levels to aid in diagnosis and management of medullary thyroid carcinoma (MTC) and other disorders affecting calcitonin secretion. Patients with MTC may show significantly elevated calcitonin levels, especially in cases where baseline levels are normal but stimulated levels increase significantly post-treatment. This test involves multiple timed specimen collections pre- and post-drug treatment administration to evaluate calcitonin response.
Special Instructions
Please refer to the Endocrine Appendix of the LabCorp Directory of Services for instructions on multiple specimen testing. This panel requires drawing multiple tubes at set time points, starting with a baseline collection, followed by treatment intervention (e.g., drug administration), and subsequent timed collections. Consult the clinician to confirm series necessity before proceeding with sample collection.
Limitations
Results obtained using the DPC Immulite 2000 ICMA methodology may vary from those obtained with other methods or kits and should not be used interchangeably. Interpretation should consider patient-specific factors and clinical correlation is recommended when evaluating results. The test is intended to be used in combination with clinical evaluation and other diagnostic tools. Timing of specimen collections is crucial and deviations from the schedule may impact results.
