Abstract :Background: It was aimed to investigate the relationship between neutrophil-lymphocyte ratio insert ignore into journalissuearticles values(NLR);, platelet-lymphocyte ratio insert ignore into journalissuearticles values(PLR);, eosinophil-lymphocyte ratio insert ignore into journalissuearticles values(ELR);, serum total immunoglobulin E insert ignore into journalissuearticles values(IgE); values and allergy test positivity in patients with allergic rhinitis insert ignore into journalissuearticles values(AR);. Methods: The study is a descriptive study with a retrospective design. Data on patients aged 0-18 years with a diagnosis of AR were investigated retrospectively. Age, gender, hemogram parameters insert ignore into journalissuearticles values(leukocyte, eosinophil, lymphocyte, thrombocyte);, total IgE values, allergy history and allergy test positivity were evaluated. A p value of less than 0.05 was considered as a statistically significant result. Results: In the study, the data of 230 pediatric patients with AR were analyzed. The median age of the children was 13 years insert ignore into journalissuearticles values(10-18);. Of the patients 57.4% insert ignore into journalissuearticles values(n=132); were male, 42.6% insert ignore into journalissuearticles values(n=98); were female. All laboratory values, except PLR, of the patients with positive allergy test were higher than the patients with negative allergy test. This elevation in WBC, neutrophil, absolute eosinophil, eosinophil percentage, total IgE and ELR values was statistically significant insert ignore into journalissuearticles values(p<0.05);. When the cut-off point for ELR is 0.066; sensitivity was 78.8% and specificity was 70.4%. When the cut-off point for total IgE is 134.5; sensitivity was 75.8%, specificity was 74.1% insert ignore into journalissuearticles values(p<0.001); Conclusions: According to study results, 3 out of every 4 patients with positive allergy test can be detected by ELR and total IgE values. Since allergy tests cannot be performed in every clinics, it is extremely important to evaluate the success of more practical and accessible blood tests in predicting allergy test positivity.
