title: Decreased anion gap associated with monoclonal and pseudomonoclonal gammopathy.
abstract: Nine patients with monoclonal and one with pseudomonoclonal gammopathy were found to have a decreased anion gap. Eight of the patients had multiple myeloma, one has plasma cell leukemia and one had chronic active hepatitis. In all of the the decreased anion gap was associated with an increased concentration of IgG greater than 5 g/dl.
