Description
Serum, Procalcitonin is a peptide precursor of the hormone calcitonin, which regulates and maintains calcium equilibrium in the body. It is produced naturally in the body and serves as a marker for septic infection. This test determines the level of procalcitonin in blood and aids in the early detection of severe bacterial infections. Pro-inflammatory stimuli during bacterial infection, sepsis during operation/trauma lead to an increase in circulating procalcitonin levels beyond the normal range.

Sample Required:
The Procalcitonin, Serum test requires a blood sample obtained through a venipuncture, typically from a vein in the arm.
Test Time:
The test can be processed within a few hours, and results are usually available within a day.
Test Normal Range:
The normal range for procalcitonin in the serum is typically less than 0.05 ng/mL. However, normal ranges may vary slightly among different laboratories.
What is the test?
The Procalcitonin, Serum test measures the levels of procalcitonin, a protein produced in response to bacterial infections, in the bloodstream. It is used to help diagnose and monitor severe bacterial infections, particularly in the context of systemic inflammation and sepsis.
Test Procedure:
During the test, a healthcare professional will collect a blood sample from a vein in your arm. The sample is then sent to a laboratory, where the procalcitonin levels in the serum are measured using specialized techniques.
When to take the test:
The Procalcitonin, Serum test is usually ordered when there is suspicion of a severe bacterial infection, such as pneumonia, sepsis, or meningitis. It is often used to differentiate between bacterial and viral infections, guide antibiotic therapy, and assess the response to treatment.
Who should take this test:
The Procalcitonin, Serum test is typically performed in individuals who present with severe symptoms of infection, particularly those at risk of developing complications such as sepsis. It is commonly used in hospital settings and intensive care units.
Precautions for exceptional cases (pregnancy, etc.):
In exceptional cases, such as pregnancy, it is important to inform your healthcare provider before undergoing the Procalcitonin, Serum test. Pregnancy itself can influence procalcitonin levels, and the interpretation of results may need to be adjusted accordingly. Your healthcare provider will provide specific instructions based on your circumstances.
FAQs for Procalcitonin, Serum Test:
Q1: Is fasting required for the Procalcitonin, Serum test?
A: No, fasting is generally not required for this test. You can usually have your blood drawn at any time, regardless of food intake.
Q2: What can elevated procalcitonin levels indicate?
A: Elevated procalcitonin levels in the serum are often associated with severe bacterial infections, including pneumonia, sepsis, and meningitis. However, other factors such as inflammation and certain non-infectious conditions can also contribute to elevated levels.
Q3: Can the Procalcitonin, Serum test distinguish between bacterial and viral infections?
A: The Procalcitonin, Serum test can provide valuable information to differentiate between bacterial and viral infections. Elevated procalcitonin levels are more commonly seen in bacterial infections, while viral infections typically result in lower or normal levels.
Q4: How is the Procalcitonin, Serum test different from a standard complete blood count (CBC)?
A: While a complete blood count (CBC) provides information about various components of the blood, the Procalcitonin, Serum test specifically measures procalcitonin levels, which is a marker of bacterial infection and systemic inflammation. It provides more targeted information in the context of severe infections.
Q5: Can the Procalcitonin, Serum test replace other diagnostic tests for bacterial infections?
A: The Procalcitonin, Serum test is a valuable tool in the diagnosis and management of bacterial infections, especially in critically ill patients. However, it is typically used in conjunction with other clinical findings and tests to provide a comprehensive assessment. Your healthcare provider will determine the most appropriate diagnostic approach based on your specific situation.
