Subjects with microcytic hypochromic indices were screened for beta thalassemia trait. Data were analyzed using SPSS 24.Results: Mean HbA2 was 5.34 +/- 0.6% (range 4.1% - 6.3%). HbA level was 93.31 +/- 0.6% (range 92.40 - 94.10%). HbF level in carrier group was 1.3 +/- 0.82% (range 0.70 - 3.10%).Conclusion: The overall frequency of beta thalassemia carriers was found to be 2%.
