Fungal infection gone & 107 allergens test
Three weeks after the last appointment, we were back at Dr Ling's room. This time she voluntarily told us that the swab test confirmed the fungal infection diagnosis. She was also satisfied with mum's recovery after performing a physical examination.
After we told her that despite mum having no prawn allergy for most of her life, the past 3 times she had prawns consistently caused itchy rashes. Mum showed her a photo of the rashes, which the Dr Ling said was bad. Hence, mum was advised to avoid prawns, regardless of the results of the 107 allergens test. I also signed up for the test.
Dr Ling explained that the allergen test is testing for the presence of IgE. There are 5 types of antibodies i.e. IgG, IgM, IgA, IgE, and IgD. Allergic reaction that's caused by production of IgE to fight allergens is the most serious compared to other types of antibodies and hence allergy test focuses on IgE. So, even if the IgE allergy test is negative for prawns, mum's allergic reaction could still be caused by presence of other types of antibodies fighting the allergen (prawns).
As for the allergy test, it normally takes a week for the results to be out but the doctor succeeded in getting them a few days later. Unlike her reaction, I was disappointed that there was no positive result for any of the allergens for me. As for mum, it was weakly positive for cockroach, which the doctor said it's a non-issue. Haiz, I was hoping for to get some positive results that might help with managing our rhinitis better by avoiding or minmising exposure to the allergen(s).
