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: Observation
Method: Probe.amp.tar

What it does not mean

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

Key facts

SARS-related coronavirus E gene [Cycle Threshold #] in Specimen by NAA with probe detection

SARS-related coronavirus E gene

Quantitative detection of nucleic acids within the envelope (E) gene of SARS-related coronavirus in various specimens, including lower & upper respiratory, serum, stool or urine, by nucleic acid amplification with probe-based detection. Various assays have been developed that contain primer-probe sets targeting the E gene. [https//www.who.int/emergencies/diseases/novel-coronavirus-2019/technical-guidance/laboratory-guidance]
