Chemiluminescence immunoassay (CLIA) for the determination of Procalcitonin (PCT) in human serum and plasma on the automated LIAISON® and LIAISON® XL random access analyser (DiaSorin)

Liaison title

Assay characteristics

  • Two-step chemiluminescence immunoassay using two different highly specific monoclonal antibodies for the coating of the solid phase (magnetic particles) and for the tracer
  • Sample material: Serum or plasma
  • Sample volume: 100 μL
  • Incubation time: 16 min
  • Measuring range: 0.020 up to 100 μg/L
  • Functional assay sensitivity: 0.04 μg/L
  • High-dose hook: No high-dose hook effect detectable up to 2000 μg/L



The intra-assay and inter-assay coefficients of variation are <5% and <10%, respectively.
