Number of participants with positive skin patch test reaction, scored using the North American Contact Dermatitis Group (NACDG) criteria, to three novel surfactant antigens.
Time Frame: Five days
|
NACDG Scoring as follows: 6=no reaction, 4=doubtful (faint erythema with no induration), 1= mild (erythema, induration, +/- papules), 2=moderate (erythema, induration, papules, vesicles), 3=severe (intense erythema, induration, coalescing vesicles, bullae, spreading), and 5= irritant.
