Given the gravity of this diagnosis all efforts must be made by the clinician to exclude alternative and more treatable entities. Frequent serology testing involves searching for treatable disorders including vitamin B12 deficiency parathyroid anomalies and monoclonal gammopathies. Case presentation We present the case of a 78-year-old Caucasian man with all three of the aforementioned commonly searched for disorders during an investigation for amyotrophic lateral sclerosis. Conclusions The clinical utility of these common tests and what they ultimately mean in patients with amyotrophic lateral sclerosis is discussed along with a review of the literature. Introduction Amyotrophic lateral sclerosis ALS is a progressive and devastating neurodegenerative disorder that affects primarily motor neurons and is the most common type of motor neuron disorder. Because of the near-uniform kiss of death implications that a diagnosis of ALS carries all efforts must be made to exclude alternative diagnoses. Typical investigations look for any potential treatable cause of the patient s condition. In addition to electrodiagnostic studies the usual investigations include neuroimaging studies to exclude anatomic structural processes such as cervical myelopathies and typical laboratory investigations to search for any potential treatable metabolic abnormality. In particular among the most common .
