Test Description
A procalcitonin test (PCT Test) measures the level of procalcitonin in your blood. Procalcitonin is a 116-amino acid precursor of calcitonin, which is a hormone synthesized by the parafollicular C cells of the thyroid and involved in calcium homeostasis[4]. Procalcitonin is released into the bloodstream when the body is infected, and its levels can increase significantly during systemic bacterial infections[3].
Indications of the Test
The procalcitonin test is used to help diagnose sepsis and determine whether an infection is bacterial or non-bacterial[3]. It is particularly useful in the following situations:
– Detecting or ruling out sepsis in seriously ill patients
– Distinguishing between bacterial and non-bacterial causes of infections, such as meningitis
– Assessing the risk that a critically ill person will progress to severe sepsis and septic shock, or the risk of the person dying
Patient Preparation/Instructions
There are no specific patient preparation instructions for the procalcitonin test. However, it is essential to inform the healthcare provider if the patient has any known allergies or is taking any medications, as these may affect the test results.
Typical Reference Values
The reference value for procalcitonin in adults is less than 0.1 ng/mL. Levels greater than 0.25 ng/mL can indicate the presence of an infection[4].
Turn Around Time
The turnaround time for the procalcitonin test varies depending on the laboratory, but it typically takes a few hours to a day for the results to become available.
