| description | The "high sensitivity" troponin assays manufactured by different vendors have different analytical characteristics, including the limit of detection and 99% upper reference limit (URL). The quantitative results from different assays should not be compared to make clinical decisions, and reporting the quantitative result in isolation is not recommended. The troponin high sensitivity quantitative results should be reported with information about the assay and/or the interpretation, depending on the specific reporting method used in a given laboratory or hospital, that are included in the High sensitivity Troponin I [LOINC: 89577-1] and Troponin T [LOINC: 89576-3] panels. 1. The laboratory device 99th percentile upper reference limit [LOINC: 89581-3] 2. The laboratory device coefficient of variation at 99th percentile URL [LOINC: 89580-5] 3.

| 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 | ||
