Blood transfusion and its effects on DNA profiles of an individual is an important issue in the forensic context. In the present study, the effects of unfiltered whole male blood transfusion in seven female subjects were investigated by PCR-based assays on serial post-transfusion blood samples. PCR analysis of specific short tandem repeat (STR) primer pair to CSF1PO, TPOX, TH01, F13A01, FESFPS, vWA and sex specific Amelogenin loci for banding pattern of alleles generated from the pre- and post-transfusion of seven female recipients and their corresponding donors were studied. Pre- and post-transfusion DNA profiles of all the seven female recipients were found to be consistent with no evidence of the male and female donor genetic material. It is concluded that currently used PCR-based STRs and sex specific Amelogenin loci DNA profiling techniques in forensic science are reliable and informative for paternity and identity purposes in situations of transfusion of 1 or 2 U of unfiltered whole male and female blood (> 72 h old) to female recipient up to 24 h post-transfusion.
