| name | ||
| description | The quantitative cycle threshold value for the detection of nucleic acids within the N gene of the SARS-related Coronavirus (SARSr-CoV) in various specimens, including lower & upper respiratory, serum, stool or urine, by PCR with probe-based detection. This term was created for, but not limited in use to, the N3 primer-probe set used in the COVID-19 assay developed by the Centers for Disease Control and Prevention (CDC).[CDC: coronavirus/COVID-19/lab/] | |
| status | ACTIVE | |
Fully-Specified Name | ||
| component | SARS-related coronavirus N gene | |
| property | ThreshNum = Threshold Number | |
| 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 | XXX | |
| 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 | |
| method | Probe.amp.tar.CDC primer-probe set N3 | |
