There are several paternity testing companies offering what look like very cheap tests. However, not all paternity tests are of equal quality. To avoid getting an incorrect result, which could have devastating consequences, always ensure that the testing company is fully accredited, preferably by international accreditation bodies such as the AABB and ISO 17025. The International Organization for Standardization (ISO) 17025 is the world standard in the certification of competence of testing and calibration of medical diagnostic laboratories. ISO 17025 certification ensures a high level of competence and compliance for the certified laboratory, ensuring that testing is undertaken by professionals. The AABB also certifies laboratories, and runs an accreditation program specifically for high competence levels in parentage testing. The lab used by Advanced DNA Paternity Testing, Inc. is accredited by both bodies.
The company uses an adequate number of genetic markers - To cut costs, many companies will use only a small number of genetic markers, which severely limits their accuracy. They will quote a 99% accuracy which sounds high, but in fact means that 1 in every 100 of their tests results are INCORRECT - are you willing to risk that on such an important result? DNA Paternity Testing Inc. uses at least 16 genetic markers for testing, meaning the chance that these markers will assign paternity incorrectly is as low as 1 in several billion.
Many companies have hidden costs. They will lure you in with the promise of a cheap test, then charge you extra for shipping, for rapid results, or even to provide a copy of the results. DNA Paternity Testing guarantees that you will pay NO MORE than the advertised price - shipping of the test kit, results, and testing is all included.
