(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.

For the analysis of Prostate Specific Antigen (PSA), the objective of the present study was to evaluate the usefulness of the clinical inmunochromatographic tests (PIC) ECOTEST, CTK BIOTECH and MONTEST in detecting PSA in forensic samples of vaginal swabs taken as evidence in cases of crimes against sexual freedom in the Legal Medical Unit II Lima East; 2021-2022. The research design is non-experimental, applied, cross-sectional, descriptive and comparative. Fifty vaginal swabs were analyzed; each swab was subjected to the seminal fluid recovery technique and inoculated in the wells of the ECOTEST, CTK BIOTECH and MONTEST ICP cassettes. The BLUESTAR Identi-PSA forensic immunochromatographic test (PIF) was considered as a reference test (gold standar). Similar excellent results were obtained for the three ICPs (ECOTEST, CTK-BIOTECH and MONTEST): Sensitivity of 100% (CI 95%=98.98%-100%), Specificity of 100% (CI 95%=97.62%-100%), Validity Index of 100% (CI 95%=99.00%-100%), Positive Predictive Value (PPV) of 100% (CI 95%=98.28%-100%), Negative Predictive Value (NPV) of 100% (CI 95%=97.62%-100%). Similar statistical results were also obtained for the three PICs: Youden Index with a value of 1.00, ROC Curve with an AUC =1.00 at 95% CI; and Cohen's Kappa Indices with a value of 1.000 and 0.000 standard error.
