Processing Details:
Useful for:
- Serological evaluation of patients who present with a subacute neurological disorder of undetermined etiology, especially those with known risk factors for cancer
 - Directing a focused search for cancer
 - Investigating neurological symptoms that appear in the course of, or after, cancer therapy, and are not explainable by metastasis
 - Differentiating autoimmune neuropathies from neurotoxic effects of chemotherapy
- Monitoring the immune response of seropositive patients in the course of cancer therapy
- Detecting early evidence of cancer recurrence in previously seropositive patients
