ABSTRACT Objectives: To find out prevalence of ABO blood groups and to investigate their association with allergic rhinitis and relate it with Genetics. Materials and Methods: This cross sectional study was done at Kut city in Iraq from January 2015 to December 2015. 109 Participants including both sexes (18 60 years of age) were enrolled for the study during Hematology module. ABO blood group of study population was done by antisera method. A detailed history of study population regarding age, sex, family history and others was recorded on a preformed proforma. Results: In our study population, O blood group came out to be the most common (46.8% History of allergic rhinitis was reported by 55.9% of our study population. Allergic rhinitis were found high among individuals with Rh+ blood group (94.5% but the ratio was close in female and male in (55% 53% respectively. A significant association between allergic rhinitis (AR) and incident rheumatic arthritis (RA) was found in this population based cohort study. RA can occur in 31.2% of patients with AR. Blood group B was found to be at lowest risk level for allergic rhinitis (11.01% The study showed association between blood groups and allergies rhinitis as 0.072 statistically significant p value. Conclusion: In the study population blood group O being the most common is at high risk level for developing allergic rhinitis while blood group B being the most protected one. This statistically significant association of various blood groups with allergic rhinitis development could help in identifying people at risk as an aid to preventive measures.
