LOINC Code


LOINC code53707-6
nameCV2 IgG Ab [Presence] in Cerebral spinal fluid by Immunoblot
descriptionCV2 IgG in cerebrospinal fluid (CFS) can be detected by western blot assays and is highly recommended for evaluating patients with subacute unexplained basal ganglionic disorders (chorea/Parkinsonism hemi-ballismus), cranial neuropathies (particularly loss of vision, smell or taste), myelopathies, and radiculoplexopathies. CV2-IgG is also a sensitive confirmatory marker for thymoma and lung carcinoma (SCLC-small cell lung carcinomas).

propertyPrThr  =  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.
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
scaleOrd  =  Ordinal:  Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive.
methodIB  =  Immune Blot:  Applies to techniques that include electrophoretic or chromatographic separation such that position (size) of the band is part of the assessment

last change typeMIN  - change to field other than name
change reasonCollapsin response mediator protein 5 (CRMP5) Ab is also known as CV2 Ab. Changed component from Collapsin response mediator protein 5 Ab.IgG to harmonize with existing terms.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
