procalcitonin (pct) is a prohormone that has been used as a marker for the diagnosis of bacterial infections. the aim of this study was to survey pct levels in patients with cirrhosis. sixty-four patients with hepatic cirrhosis and 32 healthy blood donors were enrolled in this study. serum pct levels was detected using immunoluminometric assay. the rate of positive pct was higher in patients wi...

Introduction: About one third of the world's population is infected with tuberculosis (TB) and each year, about 1.5 to 2 million people die from TB. Procalcitonin (PCT) is an inflammatory marker that its level has variable Materials and Methods: This conducted on patients with pulmonary TB. Data were collected using a check list. The serum level of PCT was measured by ELISA test at the beginnin...

BACKGROUND This study was aimed to evaluate the analytical performance of the novel Diazyme procalcitonin (PCT) immunoturbidimetric assay on Beckman Coulter AU5800. METHODS Diazyme PCT is a latex-enhanced immunoturbidimetric assay, developed for use on laboratory instrumentations with capability of reading absorbance at 600 nm. This analytical evaluation included the assessment of limit of bl...

Plasma procalcitonin (PCT) is a highly specific marker for the diagnosis of bacterial infections and sepsis. PCT levels are usually low in viral infections, chronic inflammation or postsurgical states. The purpose of this study was to characterize PCT plasma levels in patients with various types of ileus at preoperative stage, where the other inducing factors such as a surgical stress are exclu...

BACKGROUND The diagnostic value of lung ultrasonography (LUS) and procalcitonin (PCT) in the diagnosis of lung infections is known. No studies evaluated the combination of LUS and PCT for the diagnosis of pneumonia in the emergency department (ED). We evaluated the diagnostic accuracy of the combination of LUS and PCT in the diagnosis of pneumonia. METHODS Patients with respiratory symptoms o...

OBJECTIVE Procalcitonin (PCT) is considered to be a specific marker for severe bacterial infections and sepsis. Elevated PCT levels have been reported in active autoimmune diseases without infection. The aim of this study was to assess the diagnostic value of PCT serum levels in ANCA-associated vasculitis (AAV) patients with respect to infection, disease activity and drug fever using a high sen...

BACKGROUND Procalcitonin (PCT) is an established marker for diagnosing and monitoring bacterial infections. Full-length PCT [116 amino acids that make up procalcitonin (PCT1-116)] can be truncated, leading to des-Ala-Pro-PCT (des-Alanin-Prolin-Procalcitonin; PCT3-116). Current immunoassays for PCT ("total PCT") use antibodies directed against internal epitopes and are unable to distinguish amin...
