LOINC Code


LOINC code89533-4
nameSCL-70 extractable nuclear Ab [Presence] in Cerebral spinal fluid by Line blot
descriptionThis term was created for, but is not limited in use to, the submitter's test strip, a membrane strip pre-coated with a specific set of antigens in parallel lines. If antibodies to any of those antigens are present in the patient's serum, they will bind to the specific antigen. The bound patient antibodies are then detected using labelled anti-human antibodies. Manufacturers call this method by different names, including immunoblot, line blot, and line immunoassay. 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 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 for this term is Line blot.

Fully-Specified Name

componentSCL-70 extractable nuclear Ab
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.
methodLine 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.
