What is Procalcitonin?
Procalcitonin is a protein that serves as a precursor to the hormone calcitonin. It is produced by the thyroid gland and various other tissues in the body. This protein becomes particularly significant in the medical field due to its role as a biomarker for bacterial infections and sepsis.
Why is Procalcitonin Important?
Procalcitonin levels in the blood increase in response to a systemic bacterial infection. This makes it an essential biomarker for diagnosing sepsis and guiding antibiotic therapy. Elevated procalcitonin levels can help healthcare providers determine the severity of an infection and make informed treatment decisions.
Applications in Medical Diagnostics
Procalcitonin testing is widely used in hospitals and clinics to monitor patients with suspected infections. It helps in distinguishing between bacterial and viral infections, thereby preventing unnecessary antibiotic use. This can be crucial in managing antibiotic resistance and ensuring effective patient care.
