Tm. Ho et al., EVALUATION OF THE MAST CLA ALLERGY SYSTEM FOR DIAGNOSIS OF ALLERGIES TO HOUSE-DUST MITES AND CATS, Asian Pacific Journal of Allergy and Immunology, 15(3), 1997, pp. 123-126
The MAST CLA system was evaluated against skin prick test (SPT) for di
agnosis of allergies to house dust mites (Dermatophagoides pteronyssin
us, Dermatophagoides farinae) and cats. Forty three asthmatic children
were examined by SPT and MAST CLA. Chi-square analysis indicated sign
ificant association between SPT and MAST CLA results for the house dus
t mites but not for cats. The sensitivities of MAST CLA for house dust
mites and cats were 100 and 25% respectively; specificities were all
less than 50%. The efficiency of MAST CLA for detection of allergy to
the house dust mites was 88% and 44% for cats. A significant linear co
rrelation was found between SPT wheal size and MAST CLA grade for D. f
arinae but not for D. pteronyssinus and cats. It is concluded that the
MAST CLA allergy system can be used to supplement SPT for diagnosis o
f allergies to house dust mites but not to cats.
