Kristal Hemoglobin pada Bercak Darah yang Terpapar Beberapa Sabun Cuci Piring Cair Menggunakan Tes Teichmann dan Tes Takayama

Abstract

ABSTRACT
Crime scene may leave various items of evidence, one of them bloodstain. Bloodstain might provide valuable information that indicates a lot form of violence that can be used as a solution in a criminal case. Criminals often camouflage the traces or evidence by cleaning the bloodstains using cleaning agents to cover up the crime. One of the cleaning agents that may be used by criminal is liquid dish soap. Bloodstains that contaminated by liquid dish soap may affect the results of the examination using Teichmann and Takayama tests. The purpose of this study is to describe the hemoglobin crystal in bloodstains that contaminated by liquid dish soap using Teichmann and Takayama test. In this study, there were five liquid dish soap solutions swabbed onto bloodstained slides for each tests. The results show that all 22 slides (100 %) still have positive result which means the hemoglobin crystal still could be found in the contaminated bloodstain using Teichmann and Takayama test. The conclusion of this study is liquid dish soap that used might not affect the formation of hemoglobin crystal using Teichmann and Takayama test .
