nameLambda light chains.free [Mass/volume] in Serum by Nephelometry
descriptionThis nephelometric assay provides a sensitive test for monitoring patients with monoclonal light chain diseases but no M-spike on protein electrophoresis, and may be more sensitive than immunofixation for detection of monoclonal free light chains. In some patients with non-secretory myeloma, systemic amyloidosis, or light chain deposition disease, the nephelometric free light chain assay provides a positive identification of a monoclonal serum light chain when the serum immunofixation is negative.

Fully-Specified Name

componentImmunoglobulin light chains.lambda.free
propertyMCnc  =  Mass Concentration
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemSer  =  Serum
scaleQn  =  Quantitative:  The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256
methodNephelometry
