Neuronal nuclear (Hu) antibody is present in patients with various neurological symptoms including two paraneoplastic syndromes: sensory neuropathy (PSN) and encephalomyelitis (PEM). The presence of Hu antibody strongly suggests underlying small cell lung carcinoma (SCLC). Hu antibody is identified by IFA and confirmed by Western Blot. A negative result does not exclude the possibility of SCLC or other malignant tumor.
