What is it indicated for?
N Latex FLC kappa and lambda are in-vitro diagnostic reagents for the quantitative determination of free light chains (FLC), type kappa or type lambda in human serum and EDTA-plasma. N Latex FLC kappa and lambda assays are used:
» as an aid in the diagnosis and monitoring of multiple myeloma (MM) on the BN Systems and Atellica® CH Analyzer,
» as an aid in the diagnosis of amyloidosis (AL) on the BN Systems and Atellica® CH Analyzer,
* as an aid in the evaluation of Monoclonal Gammopathy of Undetermined Significance (MGUS) on the BN Systems.
Results of FLC measurements should always be interpreted in conjunction with other laboratory and clinical findings.
Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
