SARS-CoV-2 (COVID-19) S gene [Cycle Threshold #] in Respiratory system specimen by NAA with probe detection 94642-6
LOINC Code
| LOINC code | 94642-6 | ||
|---|---|---|---|
| name | SARS-CoV-2 (COVID-19) S gene [Cycle Threshold #] in Respiratory system specimen by NAA with probe detection | ||
| description | The quantitative cross/cycle threshold (Ct) value for the detection of nucleic acids within the spike (S) gene of the SARS coronavirus 2 (SARS-CoV-2) in various respiratory specimens by PCR with probe-based detection. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | SARS coronavirus 2 S 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 | Respiratory System Specimen | ||
| 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 | ||
Additional Names | |||

Associated Observations | |||
LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations. | |||
History/Usage | |||
| first released | |||
| last updated | 2.75 | ||
| last change type | MAJ - change to name field other than Component; | ||
| change reason | Release 2.75: SYSTEM: There are 2 similar system's in LOINC: 1- Respiratory system 2- Respiratory specimen Due to an applied logic, the display in the System axis for 1 is Respiratory (adjective) without specification of sample, specimen, or other specific noun, while 2 is displayed fully as Respiratory specimen. Therefore for now we replaced 1 with Respiratory system specimen, which will affect 83 term. The result is replacing "Respiratory" with "Respiratory system specimen". This is the short approach. The bigger project is to potentially merge data that has either 1 or 2 together. This is a project to pass by the laboratory committee and will involve about 1500 concepts.; | ||
