Total immunoglobulin E (IgE) has been an indicator for early diagnosis of allergic diseases due the important role of IgE in the sensitization towards allergens. Although total IgE is a common diagnostic test that screens for possible allergic diseases, reports are still lacking on the profile of total IgE levels of allergic patients from the north-east region of Peninsular Malaysia. Hence, this study aimed to investigate the association of total IgE levels with clinico-demographic parameters and whether increasing total IgE levels were associated with certain allergic manifestations in this study cohort. A local cohort of allergic patients (n=71) diagnosed in between 2009 and 2016 in Hospital Universiti Sains Malaysia (HUSM) were evaluated for the relevance of total IgE levels in allergy diagnosis. Our study did not demonstrate significant association between total IgE with age (p=0.75) or gender (p=0.65). However, we showed that elevated total IgE levels were associated with disease severity. Our data suggests that increasing total IgE levels beyond the conventional cutoff used to define abnormal IgE levels were more commonly associated with patients presenting allergic asthma and skin allergy manifestations. Total IgE level is a useful indicator for diagnosis of allergic diseases. Although total IgE level might not be sufficient to confirm the sensitization status of an individual, it may reflect the severity of the allergic disease suffered and it has a high correlation with positive sIgE values.
