^aSpecimens were collected prior to infection (day 0 or earlier). 

^bOverall test sensitivities and specificities for serum specimens (n = 167), urine specimens (n = 198), or both types of specimens for all days tested by using the standard positive cutoff values described in Materials and Methods. 

^cOverall test sensitivities and specificities for serum specimens (n = 167), urine specimens (n = 198), or both types of specimens for all days tested by using the high-positive cutoff values described in the Results section.
