Glial fibrillary acidic protein alpha subunit IgG Ab [Titer] in Cerebral spinal fluid by Immunofluorescence   93421-6

LOINC Code


LOINC code93421-6
nameGlial fibrillary acidic protein alpha subunit IgG Ab [Titer] in Cerebral spinal fluid by Immunofluorescence
descriptionThe staining pattern of glial fibrillary acidic protein IgG antibodies includes prominent filamentous staining in the subependymal zone and pia and subpial regions of the cerebral cortex and midbrain, with sparing of the cerebellum. [PMID: 30724768]
statusACTIVE

Fully-Specified Name

componentGlial fibrillary acidic protein.alpha subunit Ab.IgG
propertyTitr  =  Dilution Factor (Titer)
timePt  =  Point in time:  To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements.
systemCSF  =  Cerebral spinal fluid
scaleSemiQn
methodIF  =  Immune Fluorescence:  Encompasses DFA, IFA, FA. Usually applies to cells and smears examined microscopically so that both the “where” and the “what” can be assessed, but can also be used on fluids in a way similar to ELISA. Does not include Cell binding assays (see CBA IFA above).
