Abstract
Task: The aims and objectives of current study were to identify the values of bloodstain pattern analysis for blood droplets on solid surface in forensic sciences. Methodology: Study design: Present study was conducted in different medical institutions of Lahore from November 2021to March 2022. Crime scene (Blood droplets on solid surface): In current study for research purpose few blood droplets of 2 individuals were dropped on different solid surfaces and consider it as crime scene. Sample collection: In this study total 10 blood samples were collected from different individuals for cross match with the droplets of blood sample collected from solid surfaces. 2, individuals how dropped their blood droplets on solid surfaces were also included in total participants of present study. Blood droplets from solid surfaces were collected with the help of cotton swab techniques. DNA analysis: With the application of Polymerase chain reaction such analysis performed and DNA released from the cell by extraction and measured the amount of genetic material than amplified its copies and separated these amplified copies from each other. The qualitatively and quantitatively comparing of DNA evidence samples are referred as DNA profiles and checking the technical correctness of analyst reports was its quality assurance.
