DNA Analysts are typically employed by forensic crime labs. They help compare DNA samples from crime scenes or victims. As a DNA Analyst, you will likely spend most of your time in a lab studying DNA samples, which may include samples obtained from blood, hair, or bodily fluids.

What they do

The main duty of a DNA Analyst is to analyze DNA samples, which are typically obtained directly from crime scenes or victims of crimes. The DNA samples are compared to other samples in the hopes of finding a match.

Obtain DNA Samples from Victims or Crime Scenes

DNA Analysts need to obtain DNA samples for comparison. The DNA samples may come from victims, suspects, crime scenes, or evidence collected at a crime scene.

In some cases, the DNA Analyst visits the crime scene with other members of the forensics team. They use equipment to obtain DNA from hair, bodily fluids, blood, and objects.

Compare DNA Samples in a Laboratory Setting

After obtaining DNA samples, DNA Analysts begin comparing them to find a match. DNA Analysts often use extensive databases containing the DNA of criminals and individuals processed by law enforcement agencies. Government employees are also often required to supply DNA samples to databases.

When comparing DNA, Analysts need to follow strict quality control procedures. This ensures the accuracy of their DNA analysis, which is often used by prosecutors when prosecuting a suspect.

Review the Work of Other DNA Analysts

DNA Analysts perform peer reviews to verify the accuracy of their findings. When working as a DNA Analyst, you may review the work of other DNA Analysts and submit your work to others for review.
