Procalcitonin
The Procalcitonin test measures the level of procalcitonin, a substance produced by the body in response to bacterial infections. Clinicians often order this test to help diagnose sepsis, a severe inflammatory response to infection, and to differentiate between bacterial and viral infections. The Procalcitonin test is particularly useful in emergency settings, intensive care units, and for monitoring treatment effectiveness in patients with suspected infections. By assessing procalcitonin levels, healthcare providers can make informed decisions regarding antibiotic use and patient management.

Clinical Information
Clinical Significance
Abnormal results from the Procalcitonin test may indicate the presence of a bacterial infection, with higher levels suggesting a more severe infection or sepsis. Conversely, low levels typically suggest the absence of significant bacterial infection. However, only a qualified healthcare provider can interpret these results accurately, considering your overall health and symptoms. Always discuss your results and any concerns with your doctor.
Reference Ranges
Reference ranges for procalcitonin levels can vary based on age, sex, and the specific methods used by the laboratory. Generally, lower levels are considered normal, while elevated levels may indicate an ongoing bacterial infection. It's essential to consult your healthcare provider for a precise interpretation of your results, as they will consider your individual health context.
Sample Preparation
Before your Procalcitonin test, no special preparation is typically required. However, it's best to inform your healthcare provider about any medications you are taking, as some may affect the results. If you have specific instructions from your healthcare provider regarding fasting or medication adjustments, please follow those guidelines. Arriving well-hydrated can also aid in the blood draw process.
