| description | Testing is done as an assessment of toxic metal retention to address public health concerns of niobium leaching into drinking water. Variability in urine volume can drastically affect the concentration of elements and to compensate for urine dilution variation, elements are sometimes expressed per unit creatinine. | |
| status | ACTIVE | |
Fully-Specified Name | ||
| component | Niobium/Creatinine | |
| property | SRto = Substance 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 | Urine | |
| 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 | |
