Gambaran Kristal Hemoglobin pada Bercak Darah yang Terpapar Beberapa Sabun Krim Menggunakan Tes Teichmann dan Takayama

Abstract

ABSTRACT
The biologic sample like bloodstains are precious physical evidence that
can be found at any crime scene. Bloodstains that be found can indicate struggle
or murderer case and identification of bloodstains found at criminal scene can
give information about actual criminal acts. The criminals often try to remove or
camouflage bloodstains by using cleaning agents like cream detergent that makes
bloodstains contamined with detergent surfactant and may be affect the chemical
bloodstains identification using Teichmann and Takayama test. The purposes of
this experiment are to know the description of hemoglobin crystal at contamined
bloodstain with some cream detergents using Teichmann and Takayama test. This
experiment is the experimental description. This experiment has done in
Biochemical Laboratory Medical Faculty of Riau University. There’re 38 slides
that made in this experiment with twice experiment (duplo). The bloodstain slides
were washed using cream detergent A, B, C, D, E, and F once until three times.
The result of this experiment was positive in all bloodstain slide that washed by
cream detergent when it tested with Teichmann and Takayama test.
Keywords: bloodstain, hemoglobin crystal, cream detergent, Teichmann and
Takayama.
