LOINC Code 85095-8: D-3-phosphoglycerate dehydrogenase IgG Line blot Ql (S)

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 D-3-phosphoglycerate dehydrogenase Ab.IgG. It is commonly used with the system or sample type Ser.

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: Line blot

What it does not mean

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

Key facts

• D-3-phosphoglycerate dehydrogenase IgG Ab [Presence] in Serum by Line blot
• D-3-phosphoglycerate dehydrogenase Ab.IgG
• The qualitative result for the detection of IgG antibodies to D-3-phosphoglycerate dehydrogenase (PGDH) antigens in serum or plasma for the diagnosis of autoimmune liver diseases, including autoimmune hepatitis and primary biliary cirrhosis. This term was created for, but is not limited in use to, the submitter's test strip, a membrane strip pre-coated with a specific set of antigens in parallel lines. If antibodies to any of those antigens are present in the patient's serum, they will bind to the specific antigen. The bound patient antibodies are then detected using labelled anti-human antibodies. Various manufacturers classify this method as an immunoblot technique. LOINC uses the immunoblot (IB) method to mean that some electrophoretic/chromatographic separation occurs such that position (size) of the band is part of the assessment (as in Western blot).
