are paternity dna tests always accurate
The number of STR Loci (genetic locations) which are examined. As a rule of thumb, the greater the number of STR Loci that are examined, the more accurate and powerful you test becomes. Current technology allows up to 16 STR Loci to be tested for routine paternity tests. Laboratories which test all 16 STR Loci are offering premium tests. In a DNA parentage test, the result (called the 'probability of parentage) is 0% when the alleged parent is not biologically related to the child and the probability of parentage is typically 99.99% when the alleged parent is biologically related to the child. Let’s look at this example concerning a paternity test. First, it is important to understand that all of us as humans share 99.9% of the same genetic code. So what we are really testing is a very small amount of DNA that helps identify who is part of our biological family. The number of times that the laboratory performs the test. The current standard to ensure 100% accuracy is to run all paternity tests two times in parallel to ensure that the results are absolutely accurate. Genex runs all tests two times before the final test report is generated. DNA paternity testing is the use of DNA profiling (known as genetic fingerprinting) to determine whether two individuals are biologically parent and child. Paternity testing can now also be performed while the woman is still pregnant from a blood draw. DNA testing is currently the most advanced and accurate technology to determine parentage. At Bio-Gene DNA we are interested in more than making certain that the testing is performed. We want to make certain that the DNA testing service you order is appropriate for your needs, even if that means refering you to another lab that may meet your needs better. In testing the paternity of a male child, comparison of the Y chromosome can be used, since it is passed directly from father to son. In the US, the AABB has regulations for DNA paternity and family relationship testing; however, AABB accreditation is not necessary. This genetic material is known as the nuclear genome of the individual, because it is found in the nucleus. Comparing the DNA sequence of an individual to that of another individual can show whether one of them was derived from the other. However, DNA paternity tests are not currently 100% accurate. The accuracy of a DNA test is dependent upon a number of factors. The main factors which affect the accuracy/power of a paternity test are as listed:
