ABSTRACT: Minor beta-thalssemia is one of the frequent causes of microcytic anemia .To screen a large population for thalassemia traits, simple diagnostic tests are needed by which iron deficiency can be differentiated from the traits. In a descriptive study data of complete blood count of 15000 men and 15000 women was measured by H*1 cell counter and evaluated; And several indices and formulae were checked to find out whether they are good discriminators or not. We found out that in a man with MCV<80 FL,RBC>7×106/mm3 and Hb<18 g/dl the probability of thalassemia traits is 90% with the same MCV in womman and a 106/mm3 RBC>6.5) 0.01 formula canxand Hb<16, the probability will be the same. Using (MCV)2 with ×MCH×help to screen the trait sensitivity of 100% in women, which was equal to value of MCV/RBC in men. conclusion :The two above mentioned formula can be used as the first step of screening of minor beta thalassemia
