Paternity tests allow you to work with up to 99.9% certainty in excluding false kinship, and are also very accurate exams even when the checks involve individuals with a high degree of kinship. There are many advantages to paternity tests, including the possibility of using not only blood samples, but also semen, hair and other tissues, including bones (in very special cases) for examination. This allows even dead animals to be tested. Normally the hair is worked (containing the hair bulb or “root”), which makes sending samples very simple, since refrigeration is unnecessary. In addition, storing them for future use is also possible, by wrapping the hair in properly identified paper envelopes.
