Blood Groups in the Philippines

Abstract

During I960 blood samples were obtained from 413 adult Philippinos living in Manila but originating from all parts of the island (Motulsky, Stransky, and Fraser, I964). The main object of this study was to determine the incidence of abnormal haemoglobins and G6PD deficiency but the opportunity was also taken to characterize the blood and serum group frequencies of this population.Blood Groups ABO System. Blood groups following ABO system are set out in Table I. MNSs System. (Table II). and anti-s sera were used.Anti-M, anti-N, Rhesus System. Anti-D, anti-C, anti-E, and anti-c sera were used and tests were done with anti-Du on all those persons negative with anti-D (Table III)

ABO blood groups and cholera

“…The results are summarized in table 1, which also includes the normal blood group distribution in the Philippines as determined in three different studies (Philippine National Red Cross, 1948-1959Lechat, Bias, Guinto, Cohen, Tolentino and Abalos, Abalos, 1968;Fraser, Giblett, Stransky and Motulsky, 1964). The patients were drawn from heterogeneous groups similar to those which constituted the subjects of the above three studies, and in particular those of Lechat et al, 1968, andFraser et al, 1964.…”

“…The patients were drawn from heterogeneous groups similar to those which constituted the subjects of the above three studies, and in particular those of Lechat et al, 1968, andFraser et al, 1964. There were no marked differences in the ABO blood group distribution in these three studies.…”

The World Distribution of Transferrin Variants and some Unsolved Problems

“…By contrast to the reported absence of transferrin variants in Polynesia and Micronesia, Filipinos have about 2 % of D variants (Fraser et al, 1964). These were reported as D 1} though it seems more likely that they are in fact D Chi variants.…”
