Influence and elimination experiment resulting in a false positive test result, which was affected by serum rheumatoid factor levels. Eleven different serum concentrations of rheumatoid factor were tested for 2019-nCoV IgM and IgG. From left to right, RF was 16.1, 85.0, 133.0, 187.5, 231.7, 284.3, 331.0, 390.5, 450.0, 490.6, and 539.7 (IU/mL). A is the original result, B and C are the results diluted five times with normal human serum and physiological saline, respectively.
