Perfil genético en prendas procesadas con pruebas de identificación y diagnóstico hematológico en la Unidad Médico Legal II–Lima Norte, 2023
(Universidad Privada Norbert Wiener, 2023-07-18) Sarmiento Yengle, Valery Roxana; Casana Jara, Kelly Milagritos
The Forensic Biology Laboratory of the Legal Medicine Unit of North Lima has been processing different samples, in order to find evidence that can help in forensic investigations. This has been using hematological identification and diagnostic tests such as the Adler Test, Hexagón Obti and Bluestar to determine the presence of blood, which can be transported for genetic analysis; For this reason, the main objective of this investigation was to determine if the previous use of hematological identification and diagnostic tests affects the subsequent obtaining of the genetic profile in processed garments, using an applied methodology, of a quantitative approach and of a non-experimental design, with a sample of 13 garments analyzed in both forensic laboratories. Once these data were obtained, they were analyzed using the IBM SPSS STATICS Software, version 20. Likewise, for the hypothesis test, Fisher's exact test was used, derived from a Pearson Chi-square analysis; having as results the amplification of 100% of the samples analyzed with the Adler Test and 88.9% of the samples analyzed with Bluestar, however, it was not possible to obtain results from the Hexagón Obti since the samples worked with this reagent were not analyzed. in the laboratory of Molecular Biology and Genetics. Coming to the conclusion that the previous use of hematological identification and diagnostic tests does not affect the subsequent obtaining of the genetic profile in processed garments, because the genetic profile of 92.3% of all the samples analyzed was obtained.
