The Benefits of a PCR Test

 

PCR tests have become very common these days, especially since the emergence of the Covid-19 disease. PCR stands for polymerase chain reaction and it is a very good technique of DNA testing. This method uses very tiny samples for identifying the DNA of individuals. The following are some of the advantages of using PCR.

First of all, a PCR test amplifies DNA. The main advantage of this rapid antigen test in the field of forensic science is that scientists can use it for amplifying it or making several copies of parts of the DNA that widely vary between different people, known as VNTRs. With this device, whichever small amounts of the DNA attained can be easily amplified. Through comparing the various VNTRs, scientists can be able to determine if the DNA sample is a match as compared to the defendant’s DNA.

Another area that PCR tests can be helpful in is law enforcement. Rapid antigen test for travel is one of the best techniques for legal investigations as well as crimes where only small amounts of DNA are acquired. Actually, other methods of DNA testing may not be able to identify DNA where there are fewer samples. The outcomes of most investigations these days depend on the quantity as well as quality of DNA samples attained.

The fact that PCR duplicates the available samples through transcription means that it improves the likelihood of identifying the source of the DNA samples. Using this PCR technique, a lot of offenses have been successfully solved.

Last but not least, PCR can help ensure better HIV testing. PCR is also very useful in HIV testing because it is more sensitive and accurate. Instead of searching for the presence of HIV antibodies, PCR directly looks for pro-viral DNA. Due to the complexity of this test, it is 98 percent accurate at 29 days from an assumed exposure or contact.
