Background: Malaria can be transmitted through transfusion of blood
infected with Plasmodia, which can be disastrous for an immune
compromised recipient. The screening of donated blood units for
malarial parasite should be practiced.
Objective: To determine the frequency of malaria in blood donors and
identification of Plasmodium species. The sub aim of the study was to find
the frequency of different blood groups among the donors.
Material and Methods: It was an observational study carried out at the
Department of Hematology and Transfusion medicine, The Children’s
Hospital and Institute of Child Health, Lahore from 1st July, 2015 to 31st
December, 2015. After taking informed consent, 6000 healthy donors
who fulfilled the blood donation criteria were consecutively selected.
Immuno chromatographic rapid diagnostic kits (ICT) were used for
screening of malaria followed by the examination of Geimsa stained
peripheral blood smears of all the positive cases under light microscope
for species identification. The data was analyzed by using SPSS 16. The
quantitative variables including age and weight are presented as mean
and standard deviation while qualitative variables including malaria
positive cases, species of Plasmodium and types of blood groups are
presented as frequency.
Results: Out of 6000 donors, 5999 were males and 1 was female. 30(0.5%)
donors were found positive for malaria with 28 of them infected with
Plasmodium vivax. B+ve was the most common blood group among the
donors studied.
Conclusion: The study concludes that frequency of malaria in blood
donors is 0.5%and the screening of malaria should be done in all
donated blood units.
