Frequency of Kidd Blood Group in a Section of Lahore Population.

Abstract

The prevalence of Kidd blood group was studied among 310 healthy volunteers. Jk ^A- was the most common blood group. Found in 91.29%, JK^b was the next most common being 87.74% followed by JK^B+ being 12.26% and ^a+was the rarest group with a frequency of 8.7%. When tested for both anti-JK^a and anti-JK^a+ the most common group was JK^(a-b-)  present in 80.09% followed by JK ^(a-b+) (10)%, JK^(a+b-)(6.77%), while the least common group was JK^(a+b+) (0.96%). The proportion of individuals with JK^a- is significantly higher (P<0.005) in our population (91.29) as is significantly higher (p<0.005 in our population (91.29% as compared to Caucasian(23.6%). Whereas about 50% have phenotype JK^(a+b+)’ only 0.96% of our population had this phenotype (P<0.005).
