New Genetic Reference Materials Improve DNA Testing Accuracy
The National Institute of Standards and Technology (NIST) has released new forensic genetic reference materials to help forensic laboratories improve the accuracy and reliability of DNA testing. These reference materials are used as quality control tools to check that DNA testing instruments, methods, and analysis processes are working correctly.
In forensic investigations, DNA samples collected from crime scenes are often degraded, very small in quantity, or mixed with DNA from multiple individuals. These types of samples can be difficult to analyse and may affect the accuracy of results if laboratory procedures are not properly tested and validated. The new genetic reference materials help laboratories test their processes and ensure they can accurately analyse complex DNA samples.
The introduction of these reference materials helps forensic laboratories maintain testing standards and improve the consistency of DNA analysis. Accurate DNA testing is important in criminal investigations, missing persons identification, disaster victim identification, and legal cases where forensic evidence is presented in court.
This development strengthens quality assurance in forensic DNA testing and supports ongoing improvements in forensic science and laboratory practices worldwide.
