Abstract
Farr method (Farr assay, Farr immunoprecipitation assay) quantifies the antidouble-stranded DNA (anti-dsDNA) antibodies—that is, antinuclear antibodies (ANA). It measures the capacity of radiolabeled antigen to bind with antibody. Between 60% and 80% of patients with systemic lupus erythematosus (SLE) have circulating antibodies to dsDNA at some time during their illness, and the Farr assay is considered to be the most specific method for detecting these ANA.
