Forensic DNA Test

What is a Forensic DNA Test?

Forensic DNA tests are conducted to provide investigators with information that can be used to identify individuals who may have been involved in a crime. A DNA sample is typically collected from a crime scene, and the genetic information it contains is then compared to samples from potential suspects. If there is a match between the two samples, it can be used as evidence that the suspect was at the scene of the crime.

There are two main types of forensic DNA tests: nuclear DNA testing and mitochondrial DNA testing. Nuclear DNA testing looks at the chromosomes inside cells, while mitochondrial DNA testing looks at the mitochondria. Nuclear DNA tests are more accurate than mitochondrial DNA tests, but they require a larger sample size. Forensic DNA tests can be used to solve crimes ranging from burglary and assault to murder and rape.

How Does Forensic DNA Testing Work?

Forensic DNA testing is a type of genetic testing that uses crime scene DNA samples to establish the suspected offender’s genetic profile. The DNA sample is then matched to the suspect in order to confirm or deny their involvement in the crime. However, there is a procedure that needs to be followed which involves legal representatives, investigators and the court of law in order to get a forensic DNA test.

Applications of Forensic DNA Testing

The use of DNA testing in forensic science has revolutionized the field of criminal investigation. By utilizing techniques such as DNA profiling and DNA typing, law enforcement agencies are now able to identify suspects with a high degree of accuracy. In addition, DNA evidence can be used to corroborate witness testimony and connect crimes to specific individuals. Here are a few examples of how forensic DNA testing is being utilized today: Crime scene investigation, cold cases, parentage testing, etc.

How to Get a Forensic DNA Test

If you want to get a forensic DNA test, there are a few things you need to do. First, you need to find a reputable laboratory that offers this type of testing. Forensic Genetics Laboratory offers forensic DNA testing to aid in identification problems for the investigative and legal community worldwide. Second, you need to collect a sample of DNA from the crime scene AND from the person, you suspect committed the crime. This can be done by swabbing an item at the crime scene, AND by collecting a saliva sample from the suspect. You need to submit BOTH samples to the laboratory for analysis. Once the results are back, you will be able to see if there is a match between the DNA at the crime scene and the DNA of the suspect.
