As a forensic phlebotomist, you collect evidence samples of blood from crime scenes to aid law enforcement in their investigations. Your responsibilities center around collecting blood and other specimens commonly associated with crime scenes. Depending on the crime, you may also administer drug tests. The second aspect of the job is to test those samples in a laboratory. The nature of this job makes it an on-call position, as the investigators never know when they might need your assistance. Other duties in forensic phlebotomy include creating detailed reports on the samples you test, properly preserving any specimens you take, and possibly testifying in court.
