Significant interference with the accurate measurement of anti-DNA antibodies occurs after gallium-67 scanning. The observed effect is dependent on the radioimmunoassay used. False-negative results are observed with a modified Farr assay whereas false-positive results are noted in the millipore filter assay. These spurious values are the result of persistent radioactivity in the patients' sera after administration of 67Ga citrate.
