Patch test reactions were recorded according to the International Contact Dermatitis Research Group (ICDRG
) criteria: - negative;?+ doubtful reaction, faint erythema only; + weak positive reaction; palpable erythema, infiltration, possibly papules; ++ strong positive reaction; erythema, infiltration, papules, vesicles; +++ extreme positive reaction; intense erythema and infiltration and coalescing vesicles; IR irritant reaction of different types; and NT not tested.
During the challenge phase, once again no clinically significant objective signs of skin reaction were noted in any subjects (ICDRG
grade = 0, no reaction).
The ICDRG identified indicators of good practice, including, good assessment, consistent care, good record keeping, regulations followed, staff and foster carers supported, inter-agency co-operation and follow-up after the child's death.

Patch test results were interpreted according to ICDRG criteria
These readings were interpreted according to International Contact Dermatitis Research Group (ICDRG) criteria (Table 1).
Qualitative analysis of each allergen was accessed in terms of ICDRG criteria as positive, negative or irritant.
Detailed five days readings of patch test in terms of positive, negative and irritant reactions according to ICDRG criteria i.e.
Patch test reactions at 120 hours with all the allergens applied on patients were taken as final results of study in terms of positive, negative and irritant reactions according to ICDRG criteria.
Patch test readings were read according to ICDRG criteria.
All three readings were interpreted according to International Contact Dermatitis Research Group (ICDRG) criteria.5
Results are recorded at 48, 72,120 hours and on the 7th day interpreted according to the criteria set by International Contact Dermatitis Research Group (ICDRG
