Request Info

Procalcitonin (PCT) is a 116 amino acid peptide with a molecular weight of approximately 13 kDa, synthesized primarily in the C cells of the thyroid gland, but also in various other tissues such as the lungs, liver and intestines. High levels of procalcitonin (PCT) in the bloodstream are a result of the immune response triggered by bacterial infections. The presence of bacterial pathogens stimulates the release of proinflammatory cytokines, which in turn promote the synthesis and secretion of PCT. The level of procalcitonin in the bloodstream reaches peak levels within 6 to 24 hours. The secreted PCT level is positively correlated with the severity of bacterial infection and is therefore used as an important marker in the detection of bacterial infection


The Procalcitonin Test (Whole Blood / Serum / Plasma) is a rapid chromatographic immunoassay for the qualitative detection of Procalcitonin in whole blood, serum or plasma.
