Ranges

Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ

Panels that include this biomarker

  • Free κ and λ Light Chains Plus Ratio, Quantitative 121137

    3 analytes · Serum · Fasting not stated · Turnaround 1 - 3 days

    Method and collection
    Method
    Turbidimetric
    Collection
    Sample should be allowed to clot and the serum separated as soon as possible to prevent hemolysis. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
