LOINC Code 88723-2: Asialoganglioside GM1 IgG+IgM IA Qn (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 Asialoganglioside GM1 Ab.IgG+IgM. 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: IA

What it does not mean

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

Key facts

• Asialoganglioside GM1 IgG+IgM Ab [Units/volume] in Serum by Immunoassay
• Asialoganglioside GM1 Ab.IgG+IgM
• After washing off unbound substances, a horseradish-peroxidase (HRP) labeled antibody mix against human IgG and IgM is added to the wells and incubated for another two hours. Following a second washing step in which unbound antibody-enzyme reagent is removed, a substrate solution containing tetramethylbenzidine (TMB) is added to the wells. A blue color develops in proportion to the amount of antiganglioside autoantibodies bound to the microplate in the initial step. Color development is stopped by adding an acidic stop solution (diluted sulfuric acid) which turns the blue solution into yellow. The intensity of the color is measured at 450 nm. The measured absorbance is proportional to the titer of anti-ganglioside antibodies present in a given sample. The titers of anti-ganglioside autoantibodies are expressed as ratios of the calibrator and can be assigned to titer categories. Sample reports are quantitative.
