DNA testing jobs include a variety of laboratory positions. Someone in this field may study DNA for a clinical trial, test for a genetic disorder, or determine paternity. These positions are also available in forensics, or to identify criminal suspects. Most DNA testing jobs involve handling up to several dozen samples at any given time, including processing the paperwork and correctly labelling each sample for tracking. Senior roles may involve demonstrating laboratory techniques to entry-level employees, such as a technician or assistant.
