Association of ABO Blood Groups with Incidence of renal Lithiasis

Abstract

SUMMARY187 patients suffering from renal lithiasis have been examined to find out an association with ABO blood groups. It has been found that the incidence of Renal Lithiasis is comparatively higher in the patients of blood group A than in those of blood group O. The difference in percentage ratios A/(A+0)% in patients and controls is 17.96; the χ2 17.4331 for one degree of freedom shows that it differs from unity significantly. The frequencies of renal lithiasis in persons of blood group A against those of B, O and AB are 1.91, 1.59 and 1.31 respectively.
