| name | |||
| description | Usage of the IgMκ/IgMλ ratio may compensate for any fluctuation in plasma volume and hematocrit. This term was based on, but not limited in use to, the Hevylite Human IgM Kappa and Lambda assays. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | IgM.kappa/IgM.lambda | ||
| property | MRto = Mass Ratio | ||
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | ||
| system | Ser/Plas Ser = Serum Plas = Plasma | ||
| scale | Qn = 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 | ||

| formula (readable) | IgM kappa (unit g/L) is divided by IgM lambda (unit: g/L) to calculate the IgM kappa/lambda-ratio. | ||
| example UCUM units | ratio The Unified Code for Units of Measure (UCUM) is a code system intended to include all units of measures being contemporarily used in international science, engineering, and business (www.unitsofmeasure.org) | ||
