What is it indicated for?

The DiaSorin LIAISON® Vitamin B12 assay uses chemiluminescent immunoassay (CLIA) technology for the

quantitative determination of Vitamin B12 in human serum, SST serum and lithium heparin plasma. Measurements

obtained by this device are used in the diagnosis and treatment of anemia’s of gastrointestinal malabsorption. Assay

results should be used in conjunction with other clinical or laboratory data to assist the clinician in making individual

patient management decisions.

The assay must be performed on the LIAISON® XL Analyzer.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
