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.

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

Enterovirus RNA [Presence] in Pericardial fluid by NAA with probe detection

Enterovirus RNA

Viral infections are a common cause of pericarditis, and enteroviruses, including coxsackieviruses and echoviruses, are one of the viral etiologies associated with viral pericarditis. [PMID25015496] This test can be used to screen for enteroviral pericarditis, and if enterovirus RNA is present further testing may be done to determine the specific agent.
