If we are to go into the question of how accurate is DNA testing then it can be said that DNA tests are the most reliable and accurate analysis to establish parentage and genetic background. Stringent norms are set forth for the testing by the American Association of Blood Banks (AABB) and ISO and DNA testing by only laboratories accredited by these organizations is legally accepted. Again if we are to ponder how accurate is DNA testing, it yield results of 99.99 specificity or even greater.
Paternity and Maternity DNA testing Accuracy
If the patterns between father and child fail to match on more than three genetic markers, the alleged father is excluded meaning that he is not the biological father of the child. This result bears 100 percent certainty and indicates how accurate DNA testing is.
No test can prove that parentage of the father or mother of a child with 100 percent certainty. When the patterns between mother, father and child match on the DNA markers the paternity probability is calculated using the general population of its ethnic group. The testing with 99.9 percent accuracy is accepted in US courts as proof that the alleged father is the biological father of the child.
Forensic DNA testing
This testing has gained acceptance in court rooms since the late eighties. This test as evidence created a landmark in the famous 1995 trial of O.J. Simpson proving that the accused was not the murderer. Several such wrongly convicted people have been released using the DNA tests as proof. Being the most accurate form of scientific evidence this testing is accurate to a millionth of a percent, the legal system can easily establish the identity of the right criminals and save the society.
The tests conducted at Genelex are claimed to be 100 percent more discriminating above the industry standard. The average of positive results of DNA testing often exceeds 99.99 percent. Most labs test only 8 to 10 genetic markers whereas Genelex tests 16 markers ensuring the most reliable results. They also run all of the exclusions twice for confirming 100 percent exclusion which by itself shows how accurate DNA testing is. They provide affidavits, testimony and depositions in the court. The courts have been accepting their results consistently in court and by child support and Immigration agencies after extensive scrutiny.
DNA testing that provides results of exclusion are mostly 100 percent certain that the alleged father of a child is not the biological father. The US courts accept the testing with 99.9 percent as evidence to prove or disprove a person’s identity and prove how accurate DNA testing is.
