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 Mycoplasma hyosynoviae 16S rRNA gene. 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

Mycoplasma hyosynoviae 16S rRNA gene [Cycle Threshold #] in Specimen by NAA with probe detection

Mycoplasma hyosynoviae 16S rRNA gene

Mycoplasma hyosynoviae is a difficult organism to identify by culture. Quantitative PCR methods can more successfully surveil M. hyosynoviae in swine herds because it can be performed directly on clinical samples that may contain small numbers of bacteria. [PMID7532205] Specimen types for this test include fresh tissues, joint fluids and tonsil or joint swabs.
