AllergensOverall, Bla g2 was infrequently detectedin study group homes (n = 16), with median levels at baseline and exit visits less than its DLof 0.196 lg/g. Although Bla g2 was generallyless frequently detected at the exit visit (6%,6%, and 0% ‡ DL in child’s bedroom, kitchen,and living room, respectively) than the baselinevisit (6%, 19%, and 12% ‡ DL, respectively),these decreases were not significant. Dust miteallergen, particularly Der p1 (the predominantdust mite species in the Seattle area46) andMite Group 2, was detected more frequentlythan Bla g2. The percentage of Der p1 resultsequal to or greater than the DL significantlydecreased from baseline (75%) to exit visit(44%) in the living room (P = .059 [marginallysignificant]), but there was no significantchange in the child’s bedroom (75% to 69%).The percentage of Mite Group 2 sample resultsequal to or greater than the DL significantlydecreased between baseline and exit visitsin both the child’s bedroom (94% to 75%,P = .083 [marginally significant]) and the livingroom (75% to 44%, P = .025). Mus m1showed a significant increase in the percentageof results equal to or greater than the DL inboth the kitchen (25% to 62%, P = .014) andliving room (37% to 81%, P = .008); however,the majority of Mus m1 results were verylow, with medians at or just above the DL of0.002 in all locations.
