title: Correlation of blood groups with congenital disorders and gastro intestinal diseases.
abstract: Blood group studies were conducted in 330 patients suffering from gastro intestinal disorders and 180 patients with congenital malformations and compared with normal subjects. Statistical analysis has shown that (a) there is significant correlation between B group and thalassaemia, (b) congenital malformations show higher incidence in B and O groups. It would be pertinent to draw attention to the fact that B group was found to be significantly correlated to duodenal ulcer from the present study contrary to the early reports. In addition, these observations show that blood groups are linked with diseases.
