Atypical Levels of Heavy Metals, Creatinine, Haptoglobin, and Ferritin Found in Amyotrophic Lateral Sclerosis Outpatients vs. Healthy Controls: Possible Utility as a Diagnostic Biomarker

Heavy metal toxicity has been conjectured as a possible risk factor for and player in amyotrophic lateral sclerosis (ALS) and other neurodegenerative disorders. To test for a correlational relationship or linkage, we conducted a retrospective study of 54 sALS and 26 healthy volunteers who agreed to serve as controls, all of whom were seen at the Personalized Regenerative Medicine Clinic (San Clemente, California USA) between 2011 and 2016.
