| name | Borrelia afzelii+burgdorferi+garinii IgG Ab [Presence] in Serum by Line blot | ||
| description | Qualitative detection of IgG antibodies against Borrelia afzelii, B burgdorferi, and B garinii species in human serum. This test does not differentiate between the Borrelia species. This term was created for, but not limited in use to, the Borrelia ViraStripe IgG assay, which uses native, purified antigens immobilized on a test strip to which patient antibodies, if present, will bind. Various manufacturers label 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 laboratory assessment (as in Western blot). Because this assay does not involve a separation step but rather uses strips with pre-fixed antigens, the LOINC Method is Line blot. | ||

Fully-Specified Name | |||
| component | Borrelia afzelii+burgdorferi+garinii Ab.IgG | ||
| property | PrThr = Present or threshold: The Property PrThr stands for “Presence or Threshold”, meaning either a) the actual presence or absence of an analyte, or b) that the amount of analyte detected is over some predetermined threshold. | ||
| 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 | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | ||
| method | Line blot = Line blot: A membrane strip pre-coated with a specific set of antigens in parallel lines that are incubated with antibodies in order to detect the targets of interest. | ||

| change reason | This term was created for an assay that uses a membrane strip pre-coated with a specific set of antigens in parallel lines. Because the antigens are seperated by electrophoresis/chromatographic separation during manufacturing, not during the test procedure itself, this test was assigned a LOINC Method of Immunoassay (IA) and not Immunoblot (IB). However, upon further review of IA, IB, and Immunoblot strip methodologies and regulatory distinctions between these, we changed the Method from IA to Line blot so that users can distinguish between these three Methods. The meaning of the term has not changed since it was created for an IB strip assay as described in the term description. | ||
