Blood evidence can be collected from the crime scene, a suspect, victim, or decedent. When collecting blood from a crime scene it is important to collect a sufficiently sized sample and a control swab. The sample must be allowed to dry completely before being packaged in a breathable container.
Collecting blood from a person (alive or dead) takes a bit more experience. Blood may be drawn from a living subject by authorized personnel only. The medical examiner may collect blood from deceased individuals during autopsy.

Whether blood is collected from the crime scene or from a person it is equally important evidence. It must be carefully collected and entered into the chain of custody to protect the integrity of the evidence.
