| description | 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. | |

Fully-Specified Name | ||
| component | Asialoganglioside GM1 Ab.IgG+IgM | |
| property | ACnc = Arbitrary Concentration | |
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | |
| system | Ser = Serum | |
| scale | Qn = Quantitative: The result of the test is a numeric value that relates to a continuous numeric scale. Reported either as an integer, a ratio, a real number, or a range. The test result value may optionally contain a relational operator from the set {<=, <, >, >=}. Valid values for a quantitative test are of the form "7", "-7", "7.4", "-7.4", "7.8912", "0.125", "<10", "<10.15", ">12000", 1-10, 1:256 | |
| method | IA = Immunoassay: Encompasses all immunoassays with a few exceptions, including Immune Blot and Immune Fluorescence, which were created based on historic usage. | |
