Interpretive Comments: Paraneoplastic syndromes are a group of rare disorders; some of which are caused by autoimmune reactions against antigens co-expressed by cancer cells and neurons. Below are the most frequent cancers associated with paraneoplastic syndromes.


Antibody Neurological DisorderAssociated Tumour
Anti-HuEncephalomyelits, Sensory neuropathySmall cell lung cancer, Neuroblastoma
Anti-YoCerebellar degenerationOvarian cancer, Breast cancers
Anti-RiAtaxia with or without Opsoclonus-myclonusBreast cancer, Small cell lung cancer
Anti-Ma2/TaBrain stem encephalitis, Limbic encephalitisTesticular cancer
Anti-AmphiphysinStiff person syndromeBreast cancer, Small cell lung cancer
Anti-CV2Limbic encephalomyelitisSmall cell lung cancer, Thymoma

Special Processing:  
Comments:  
Method of Analysis: Two different methods, immunofluorescence assay and Immunoblot, are used to detect paraneoplastic antibodies.

The use of a substrate combination of primate cerebellum and primate
intestine permits the secure differentiation of various antibodies with
neuronal specificity from other autoantibodies in the same test procedure.

A second method, immunoblot is performed to confirm findings.
Critical Information Required: CSF orders will be canceled if a serum is not received with the sample.
Storage & Shipment: Samples may be stored up to 14 days refrigerated (2C to 8C). For longer storage freeze at -20C.
