DNA testing and resolution of crime cases. If we were Gen X, we would have considered it a conspiracy theory. However, in this era of advancement and development, this does not come as a surprise. DNA testing in the criminal investigation is known as forensic DNA testing. This type of DNA testing has helped in the resolution of criminal cases with great accuracy. However, the process of forensic testing is different from that of normal DNA testing. In his post, we will focus on explaining the role of forensic testing and its role in solving crimes. 

What is Forensic DNA Testing? Understand the Basics


Forensic DNA Testing is the process of analyzing the biological samples from the crime scenes to identify the suspect. This involves the collection, extraction, and analysis of DNA samples through scientific methods. It includes different forms of analysis, such as polymerase chain reaction, DNA sequencing, and short tandem analysis. This helps in the study of samples and identification of involved suspects. The accuracy rate of this testing is 99%, which acts as proof of its accuracy and authenticity. 

What is the Procedure of Forensic DNA Testing?


The process of forensic DNA testing starts with the collection of biological samples from the crime scene. The sample may include blood, saliva, hair with follicles, fingerprints, or the body. The sample is collected with great care and precision so as not to contaminate it, as any external factor has a direct impact on the quality of the extraction of DNA. 

After that, the sample goes to the forensic lab to analyze and extract DNA through advanced DNA technology. The extraction of DNA leads to the creation of the genetic profile. This profile gets compared to the thousands of other profiles within the system to find the exact match of it or the relatives. 

 

What is the Role of Forensic DNA Testing in Solving the Crimes?


With the accurate identification of the suspect, DNA testing services have been playing an active role in solving crime cases. It not only helps in resolving the current cases but has also resolved many cases that were closed due to lack of evidence. Every individual has a unique DNA. Thus, it helps identify the real culprit and offers relief to the suspect. The murder of Nancy Marie Bennalack in 1970 was one of the popular murder cases. In October 1970, she was brutally murdered in her apartment. Nobody, even her fiance, how she was killed. However, in August 2022, after four decades, the case was closed due to advanced genealogy technology and techniques. 

Is there any Role of the Lab in the Accuracy of DNA Testing Services?


Yes, the lab plays an integral role in the accuracy of DNA testing services. The lab is responsible for the collection, analysis, testing, and interpretation of samples and data under strict regulations. These regulations ensure the accuracy and reliability of the results. Some of the key factors that play a role in the accuracy of DNA testing include the following:

  • The proper collection and storage of DNA samples using the right techniques prevent contamination that has a direct impact on the quality of results. 

  • The accredited lab adheres to the proper rules and regulations and adheres to ISO 17025 to ensure the quality of the results. 

  • The lab hires experienced and trained staff as there is a need to interpret complex DNA structures and results. 


Choose a Reliable DNA Testing Lab 


To find a reliable DNA testing lab, you must not rely only on DNA testing near me; rather, it is important to find reliable DNA testing by reading reviews online. You may also take suggestions from your family and friends. In addition, you must consider all the points mentioned in the previous section for accurate and reliable DNA testing. However, for forensic testing, the criminal investigation departments have their testing labs. 

Conclusion 


Forensic DNA testing has been playing an integral role in the resolution of crime cases. The accuracy and authenticity of testing are the reasons for its popularity. If you are looking for a reliable lab for forensic or DNA testing, then you may visit Face DNA testing lab for accurate testing.
