LOINC Code 94819-0: SARS-CoV-2 (COVID-19) RNA NAA+probe (Specimen) [Log #/Vol]
94819-0 is a LOINC code used to identify SARS-CoV-2 (COVID-19) RNA NAA+probe (Specimen) [Log #/Vol] 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 RNA. It is commonly used with the system or sample type XXX.
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 RNA. It is commonly used with the system or sample type XXX.
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.
Key facts
- SARS-CoV-2 (COVID-19) RNA [Log #/volume] (viral load) in Specimen by NAA with probe detection
- SARS coronavirus 2 RNA
- Quantitative detection of SARS coronavirus 2 (SARS-CoV-2) viral load in a specimen, such as a nasopharyngeal swab, blood, serum, or stool, by nucleic acid amplification with probe-based detection. The viral load reflects how well a virus is replicating in an infected person. A high viral load for SARS-CoV-2 indicates a significant amount of coronavirus is present in the patient.
