Özet

Objective: One of the most essential aspects of forensic science is determining the source of biological stains seen at crime scenes. In sexual assault allegations, the contrast between peripheral blood on any surface and menstrual blood is significantly crucial. The presence of D-dimer in menstrual blood is widely recognized. The purpose of this study was to examine the specificity of the test on samples collected from patients with high D-dimer levels using different sampling techniques utilizing the SERATEC-PMB Test, which can differentiate between menstrual/peripheral blood.

Materials and Method: The SERATEC-PMB test was used on 40 participants with a D-dimer level of 400 ng/mL or above, as well as 10 postmortem blood samples, in this study. The D-dimer level, patient profile, and blood sample collecting method were all taken into account when comparing the test findings.

Results: The Seratec-PMB test found haemoglobin in all of the blood samples, as predicted. Furthermore, the test yielded negative findings in all of the blood samples collected from 40 participants using various collection procedures. Two of the ten postmortem blood samples were negative for D-dimer, whereas the other eight were positive. The D-dimer level, patient profile, blood sample technique, and test findings all showed no significant differences.

Discussion and Conclusion: All tests on 40 participants with high D-dimer levels yielded negative results. It was assumed that D-dimer was not the primary predictor of the test result. It should be noted that the test may produce false-positive results in cases of postmortem peripheral blood.
