| description | Analysis of tungsten levels in 24-hour urine collections is performed to determine exposure and accumulation of the toxic metal due to environmental or occupational (e.g. military) exposure or hazards. Toxic metals are reported as units per creatinine (e.g. ug/g{creat}) to account for urine dilution variations. | |
| status | ACTIVE | |
Fully-Specified Name | ||
| component | Tungsten/Creatinine | |
| property | MRto = Mass Ratio | |
| time | 24H = 24 hours | |
| 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 | |
