RESUMO
As gamopatias monoclonais resultam de hiperprodução de um único clone anormal de células plasmocitárias ou linfócitos B. O objetivo da avaliação laboratorial nas gamopatias é demonstrar a presença, a quantidade e o tipo de proteína anormal presente no soro e/ou na urina através do estudo do perfil protéico, quantificação das imunoglobulinas e cadeias leves e avaliação da proteinúria. Este artigo descreve as principais técnicas laboratoriais disponíveis, bem como suas indicações e limitações.
ABSTRACT
Monoclonal gammopathies result from an overproduction of a single abnormal clone of a plasma cell or B lymphocyte. The purpose of the laboratory protocols in these situations is to demonstrate the presence, the characterization and the concentration of an abnormal protein detected in serum and/or urine samples. The laboratory investigation is based on the electrophoretic protein profile, quantification of immunoglobulins, free light chains and proteinuria. This paper describes the major available laboratory methods as well their indications and limitations.
