The calcitonin test is a diagnostic procedure used to measure calcitonin levels, a hormone produced by the thyroid gland's parafollicular cells. This hormone is crucial for regulating calcium levels by inhibiting bone resorption and promoting calcium deposition. The test involves drawing a blood sample, typically from a vein in the arm, to assess calcitonin levels. It is primarily used to diagnose and monitor medullary thyroid carcinoma (MTC), a type of thyroid cancer, and conditions like multiple endocrine neoplasia type II (MEN 2) and C-cell hyperplasia. Elevated calcitonin levels can indicate MTC and other conditions, while normal levels are usually below 10 pg/mL. The test may involve provocative testing if MTC is suspected despite normal baseline levels. While calcitonin's role in calcium regulation is minor compared to other hormones, the test is essential for early detection and management of thyroid-related conditions.

The calcitonin test measures the hormone calcitonin, crucial for calcium regulation. It involves a blood draw, typically from the arm, with steps including:
- Cleaning the site with antiseptic
- Using a needle to collect blood
- Covering the puncture site post-draw
Primarily, the test diagnoses medullary thyroid carcinoma (MTC) and monitors its progression. Elevated calcitonin levels can indicate MTC or C-cell hyperplasia. Normal levels are usually under 10 pg/mL, while levels above 100 pg/mL suggest potential issues. Factors like pregnancy and medications can affect results.
The calcitonin test is crucial for diagnosing and monitoring specific thyroid conditions. It primarily aids in detecting medullary thyroid carcinoma (MTC) and is especially recommended for:
- Medullary Thyroid Cancer: Used to diagnose and track MTC progression.
- Multiple Endocrine Neoplasia Type II: Individuals with a family history may undergo testing to catch MTC or C-cell hyperplasia early.
- C-Cell Hyperplasia: Helps diagnose and monitor this benign condition.
Understanding test results and considering factors like pregnancy and medications are essential for accurate interpretation.
Understanding test results is crucial for effective diagnosis and treatment. The calcitonin test measures the hormone calcitonin, which helps regulate calcium levels. Here's a brief guide to understanding your results:
- Normal Values: Typically less than 10 pg/mL, but can vary by lab.
- Elevated Levels: May indicate medullary thyroid carcinoma (MTC), C-cell hyperplasia, or other conditions.
- Provocative Testing: Used if MTC is suspected despite normal baseline levels.
Consider factors like age, gender, and medications when interpreting results. Always consult with your healthcare provider for personalized insights.
