LOINC Code 72316-3: RNA polymerase III RP155 IgG IA Ql

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 RNA polymerase III RP155 Ab.IgG. It is commonly used with the system or sample type Ser/Plas.

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: IA

What it does not mean

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

Key facts

• RNA polymerase III RP155 IgG Ab [Presence] in Serum or Plasma by Immunoassay
• RNA polymerase III RP155 Ab.IgG
• Autoantibodies (DNA directed) against the RP155 subunit (POLR3A) of RNA polymerase III can be detected by enzyme immunoassays. Results may be interpreted by humans or automated methods and used for the diagnosis of system sclerosis (SSc, diffuse and limited forms) and overlapping syndromes. This code was created for, but not limited to, the detection of RP155 autoantibodies in Euroimmun's Systemic Sclerosis (Nucleoli) Profile EUROLINE (IgG) test kit.
