Specific IgE test: sex, age and pathologies that most require this test in a Northeasten City of Brazil

Background The measurement of total serum IgE is made in some cases to investigate if there is the occurrence of allergic processes. However, does not identify specific antibodies. When it is high may indicate an allergic process, or the ability to initiate some. However, increased IgE levels may also indicate other problems such as parasitic diseases, IgE myeloma, hyper-IgE syndrome and some stages of HIV infection. Therefore, to make a diagnosis of allergy is interesting to use other allergy tests, such as specific IgE (RAST) or prick-test. We surveyed data from patients who underwent the examination of serum total IgE to know which allergic diseases that most affect the examination, which gender and age group most affected, and also calculated an average of IgE in each pathology or group of pathologies.
