Abstract

The differentiation of blood and menstrual fluid is especially important in cases of alleged sexual assault. While the identification of blood is relatively straightforward, the identification of menstrual fluid in trace evidence has been shown to be more challenging. This may be due to the complex nature of menstrual fluid that leads to intra- and inter-individual differences in composition. Nevertheless, recent advances in DNA methylation profiling have revealed promising markers for the differentiation of the two body fluids and furthermore, markers to distinguish menstrual fluid from vaginal fluid. A literature study was performed and in total, 11 markers were evaluated in this study of which seven could be validated for menstrual fluid and blood identification purposes. Marker “BLU2” (chr16:29757334) was identified as most suitable for differentiation of blood and menstrual fluid.
