What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

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 Middle east respiratory syndrome coronavirus 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: Both
Method: Probe.amp.tar

What it does not mean

The code identifies the observation or test, not the actual result.

Key facts

Middle East respiratory syndrome coronavirus (MERS-CoV) RNA [Interpretation] in Specimen Qualitative by NAA with probe detection

Middle east respiratory syndrome coronavirus RNA

Overall interpretation of presence of MERs-CoV RNA based on the findings from gene-specific PCR assays. The submitter's assays target RNA from the N2 [LOINC74473-0], N3 [LOINC: 74472-2], and upE [LOINC: 74474-8] genes in respiratory specimens (nasopharyngeal, oropharyngeal swabs, sputum, lower respiratory aspirates/washes), serum, and stool. This code was created for, but not limited in use to, the submitter's primer and probe set, NCV-2012 rRT-PCR (CDC; Catalog #KT0136),
