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 Influenza virus B lineage 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

Influenza virus B lineage RNA [Identifier] in Specimen by NAA with probe detection

Influenza virus B lineage RNA

The overall interpretation of targets related to influenza B sub-typing of influenza virus type B viral RNA. In the upper respiratory tract, clinical specimens could includenasopharyngeal swabs, nasal swabs, throat swabs, nasal aspirates, nasal washes and dual nasopharyngeal/throat swabs. Possible lower respiratory tract specimens include bronchoalveolar lavage, bronchial washings, tracheal aspirate, sputum, and lung tissue from patients with signs and symptoms of respiratory infection. This assay identifies the genetic lineage of human influenza B viruses as B/Yamagata or B/Victoria. This term was developed for, but not limited in use to, the CDC Human Influenza Virus Real-Time RT-PCR Diagnostic Panel.
