What is being analysed in calcitonin testing?
Calcitonin is a hormone produced by the thyroid gland. The analysis focuses on measuring the level of calcitonin in the blood.
What does the result signify?
The result indicates the concentration of calcitonin in the bloodstream. Elevated levels may suggest conditions such as medullary thyroid cancer or hypercalcemia, while normal levels are typically seen in healthy individuals.
Why perform the analysis?
The analysis of calcitonin is performed to diagnose and monitor certain thyroid conditions, particularly medullary thyroid cancer. It helps in early detection, treatment planning, and monitoring of the disease progression.
When should the test be performed?
The analysis is conducted when there is suspicion of medullary thyroid cancer based on symptoms, physical examination, or imaging findings. It is also performed during follow-up visits to monitor treatment response.
What type of sample is required?
A blood sample is required for the analysis of calcitonin levels. It is usually collected through a simple blood draw from a vein in the arm.
Is any prior preparation necessary?
Typically, no special preparation is required before the analysis. However, individuals may be advised to inform their healthcare provider about any medications they are taking.
How is it used?
The blood sample is sent to a laboratory for analysis. Calcitonin levels are measured using specific laboratory techniques. The results are interpreted by healthcare professionals to make diagnoses and guide treatment decisions.
What are the normal values?
You can find the normal range of calcitonin levels in the table below:
What do altered values indicate?
Elevated calcitonin levels may indicate medullary thyroid cancer or other thyroid conditions. Further evaluation, such as imaging studies or biopsy, may be necessary to confirm the diagnosis and plan appropriate treatment.
