Example of a three-band rule (bands p58, p19, and weak p50) applied to IgG blots in one laboratorya

No. of bands present% Positive blots in the following study group:
EMLBCRNE
02588287
132111312

  • a If none of the three bands is present, the serum sample is more likely to be from a patient without LB than from a patient with LB but may be from a patient with EM. If one band is present, the sample is more likely to be from a patient with early LB. If two bands are present, the sample is much more likely to be from a patient with LB but may be from a patient with early or late infection. If all three bands are present the sample is almost certainly from a patient with LB and is more likely to be from a patient with a later LB infection than from a patient with EM.
