| True positive | False positive | True positive | False positive | |

| LA | 14/15 (93) | 4/36 (11) | 15/15 (100) | 26/31 (84)b |

a
Cumulative number of A. fumigatus-infected and control rabbits that tested true or false positive over the total number of rabbits tested by day 4 after infection.
b
Significantly greater number of false-positive results by LA and SEIA than by EIA (P < 0.001).
c
Use of the criterion for SEIA that more than one sample from serially collected specimens be positive for true positivity or false positivity.
