blood evidence preservation

Blood evidence preservation involves carefully handling and storing blood samples to prevent contamination, degradation, or loss of important details. This process includes drying the bloodstain if wet, packaging it in breathable containers like paper, and keeping it in a cool, secure environment. Proper preservation ensures the blood's DNA and other forensic characteristics remain intact for analysis. This meticulous approach helps forensic scientists accurately analyze the evidence, which can be crucial for solving crimes and ensuring the integrity of the investigation.
