*a*PPV, positive predictive value; NPV, negative predictive value.↵

*b*Calculations based on a single positive result on a given day regardless of results obtained on other days; day 0 urine was collected before infection.↵

*c*Calculations based on a positive result on a given day and on at least one additional positive result on a day before the given day.↵

*d*These results are artificially low because only three negative control rabbits were tested on day 5 and one of these gave a false positive result on day 5 only.↵

*e*Data based on a total of 166 urine specimens from 33 rabbits collected on days 0 through 5 from*C. albicans*-infected rabbits and all negative control rabbits.
