blood evidence collection

Blood evidence collection is a crucial process in forensic science. When law enforcement collects blood from a crime scene, they use sterile tools like swabs or vials to avoid contamination. The collected sample is then carefully labeled and preserved to maintain its integrity. Proper techniques, such as wearing gloves and ensuring minimal exposure to air, are vital to prevent degradation. This evidence can provide DNA, blood type, and other crucial information to help solve cases. Accurate documentation and chain of custody are essential to ensure the evidence is reliable and can be used in court.
