LOINC Code
| LOINC code | 53715-9 | ||
|---|---|---|---|
| name | Paraneoplastic Ab [Presence] in Cerebral spinal fluid by Immunoblot | ||
| description | Paraneoplastic Autoantibody Cerobrospinal Fluid (CSF) Qualitative test by Immunoblot (Western Blot). Western blot testing is indicated in the infrequent situation that interference by coexisting nonneuronal-specific autoantibodies precludes IFA (Immunofluorescence Assay) interpretation. It is not cost-effective for routine serological screening. Information from Mayo Medical Laboratory, https://mmlaccess.com, accessed 2008 02 18. Paraneoplastic syndromes are autoantibody-mediated neurologic disorders associated with underlying tumors. These syndromes arise when systemic tumors express antigens normally found only in neural tissues. | ||
| status | ACTIVE | ||
Fully-Specified Name | |||
| component | Paraneoplastic Ab | ||
| 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 | CSF = Cerebral spinal fluid | ||
| scale | Ord = Ordinal: Ordered categorical responses, e.g., 1+, 2+, 3+; positive, negative; reactive, indeterminate, nonreactive. | ||
| method | IB = Immune Blot: Applies to techniques that include electrophoretic or chromatographic separation such that position (size) of the band is part of the assessment | ||

Associated Observations | |||
LOINC codes that represent optional associated observation(s) for a clinical observation or laboratory test. A LOINC term may represent a single associated observation or panel containing several associated observations. | |||
History/Usage | |||
| test rank | 8993 of 2000 most commonly performed tests by labs in USA | ||
| first released | |||

| last change type | MIN - change to field other than name | ||
| change reason | 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. | ||
