Measurement of calcitonin by immunoassay analyzers

Background: Since Nichols Institute Diagnostics (NID) ended production of their automated calcitonin immunoassay, evaluation of an alternative calcitonin assay was necessary.

Methods: Calcitonin measured by the NID procedure was compared with a test from Diagnostic Products Corporation (DPC)...

Keywords: auto-analyzer, calcitonin, method comparison

Alternative antibody for the detection of CA15-3 antigen: a European multicenter study for the evaluation of the analytical and clinical performance of the Access® BR Monitor assay on the UniCel® DxI 800 Immunoassay System

Background: Cancer antigen CA15-3 antigen is known as a valuable marker for the management of breast cancer.

Methods: The analytical and clinical performance of the Access® BR Monitor Immunoassay System (Beckman Coulter) was evaluated at five different European sites and compared with a reference system, defined as CA15-3 on the Elecsys® System (Roche Diagnostics).

Results: Total imprecision (%CV) of the BR Monitor ranged between 5.5% and 11.7%, and inter-laboratory reproducibility between 3.4% and 5.1%...

Keywords: breast cancer, CA15-3, diagnosis, method comparison

Alternative antibody for the detection of CA19-9 antigen: a European multicenter study for the evaluation of the analytical and clinical performance of the Access® GI Monitor assay on the UniCel® DxI 800 Immunoassay System

Background: Gastrointestinal cancer antigen CA19-9 is known as a valuable marker for the management of patients with pancreatic cancer.

Methods: The analytical and clinical performance of the Access® GI Monitor assay (Beckman Coulter) was evaluated on the UniCel® DxI 800 Immunoassay System at five different European sites and compared with a reference method, defined as CA19-9 on the Elecsys System (Roche Diagnostics).

Results: Total imprecision (%CV) of the GI Monitor ranged between 3.4% and 7.7%, and inter-laboratory reproducibility between 3.6% and 4.0%...
