Is calcitonin a tumor marker for?

Calcitonin is a tumor marker primarily associated with medullary thyroid carcinoma (MTC). MTC is a rare form of thyroid cancer that originates from the C cells (parafollicular cells) of the thyroid gland. These tumor cells produce excessive amounts of calcitonin, resulting in elevated levels of the hormone in the bloodstream. Therefore, measuring calcitonin levels through a blood test serves as an important diagnostic tool for detecting and monitoring MTC. Calcitonin levels can help in the early detection, diagnosis, staging, and follow-up of MTC patients. However, it's important to note that calcitonin levels alone cannot provide a definitive diagnosis, and further evaluation and imaging studies are often necessary to confirm the presence of MTC.

Testcare FAQ

Is procalcitonin a good marker for infection?

Procalcitonin is a valuable marker for bacterial infections, aiding in distinguishing them from viral infections. Elevated levels prompt clinicians to investigate potential bacterial involvement. However, it is not specific to TB and should be used in conjunction with other diagnostic methods.

What is procalcitonin test for TB?

The procalcitonin test is not specifically designed for tuberculosis (TB). TB is primarily diagnosed through tests like the tuberculin skin test, interferon-gamma release assays (IGRAs), and chest X-rays. Procalcitonin is more useful in identifying bacterial infections.

What is the function of the procalcitonin?

Procalcitonin is a precursor to the hormone calcitonin. Its main function is to increase during bacterial infections and sepsis, serving as a biomarker for systemic inflammation. It helps clinicians differentiate between bacterial and viral infections.

What does it mean if procalcitonin is high?

High procalcitonin levels often indicate a severe bacterial infection, especially in the bloodstream. Elevated levels can signal systemic inflammation, guiding clinicians to assess and manage bacterial infections.
