^aAt least one reactive band was required for a positive WB. The recommended combination is boxed. 

^bBand intensity equal to or greater than that of a strongly reactive control serum sample. 

^cSensitivities were determined with the data of 149 sera from patients with erythema migrans or acute neuroborreliosis.
