Why is it important to use gloves while handling evidence?

Using gloves while handling evidence is essential primarily to prevent contamination. Evidence collected at a crime scene can be vital for investigations and prosecution, and any foreign substances, such as fingerprints, hair, skin cells, or other materials that may come from the person collecting the evidence can alter its integrity. Contamination can lead to misinterpretation of results, wrongful accusations, or the loss of crucial information that might be needed to solve a case.

Maintaining the purity of the evidence ensures that it remains admissible in court and can be used effectively to support investigations. When forensic professionals wear gloves, they minimize the risk of transferring their own DNA or other elements onto the evidence, which preserves it for accurate analysis later. This practice underscores the importance of handling evidence with care to uphold the standards of forensic procedures.
