LOINC Code 94644-2: SARS-CoV-2 (COVID-19) ORF1ab region NAA+probe (Respiratory system specimen) [ThreshNum]
94644-2 is a LOINC code used to identify SARS-CoV-2 (COVID-19) ORF1ab region NAA+probe (Respiratory system specimen) [ThreshNum] in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component SARS coronavirus 2 ORF1ab region. It is commonly used with the system or sample type Respiratory System Specimen.
What is this code?
LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component SARS coronavirus 2 ORF1ab region. It is commonly used with the system or sample type Respiratory System Specimen.
When is it used?
- Used in lab systems, EHRs, and clinical data exchange.
- May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
- Status: ACTIVE
- Order vs observation: Observation
- Method: Probe.amp.tar
What it does not mean
- The code identifies the observation or test, not the actual result.
