Wondering how many different ways there are of knowing if an alleged man is the biological father of a child? Do you really think that paternity testing is the only test available? Well if so you are wrong. There are actually a range of tests available which can help you know whether a man is the real father of a child or not. And further to this, what is so great about the science of DNA relationship testing in this day and age is that in some cases you do not even need to test the alleged father.

Paternity testing is of course the most obvious choice. If the father is available and willing to be testing you can carry out the test directly be testing his DNA sample and that of the child. A paternity test will show with astounding accuracy whether he is or is not the biological father of the child. All you need to do is provide the DNA samples for the test. Wondering how this is done? All you need is just a click away. There are many laboratories that sell these types of services online. Once you place your order, they send you a kit with all the oral swabs you need to collect the samples and the easy paper work you need to fill in. In a few days, you could have your results.

So perhaps the father has passed away or is in some remote part of the world and entirely inaccessible. What now? Well you might still be able to carry out a home paternity test . If you lived with the man, you could find you are still in possession of something he owned, perhaps some cigarette butts, his sunglasses, a hat or his tooth brush. If you do have any of these samples (a many more are possible) are in luck. You can send the sample you have available along with a sample of the child. The samples of the father and the child do not even need to be the same. You can send a tooth brush for the father and an oral swab for the child.

Are both parents of the alleged father still alive? Well this would just be great. DNA tests are today so advanced that it is possible to reconstruct the alleged missing fathers profile by using the DNA of both his parents. It is crucial however; that both grandparents can provide their DNA sample as testing with grandparents is only accurate in this way. Once you have the samples of both grandparents you need to obviously also include the sample of the grandchild. The results will show the likelihood that the grandparents tested are the biological grandparents of the grandchild.

Aunt and uncle testing is a good way of indirectly establishing the paternity of a child. The child of the alleged father must of course have a genetic similarity with the blood relatives of his or her father. If there is no genetic similarity, then it most likely would indicate the child is not related to the untested, alleged father. Aunt or uncle testing will show a probability of relationship between the child and his or her alleged biological relatives.

Siblings who need to know if they share the same father can do a sibling DNA test. The test can be done between male and female siblings, only female siblings or only male siblings. But it is important to note that depending on the gender of the people taking part in the test, there will be a different test recommended. For example, if the test participants and males and females then the right test to do is the full STR test. On the other hand, if the people taking part in the test are female, an X chromosome test will be the test to opt for.

Male alleged relatives who want to know if they share the same paternal line (and thus, whether they share the same biological dad) can chose to do a Y chromosome test. This test is extremely precise and accurate and will confirm paternity of the male involved. If the tests males have the same father, they will also have the same Y chromosome profile.

As we have seen, there are many ways of establishing the issue of paternity even without testing the father. Depending on your particular situation and the people involved, there is bound to be a DNA test for you.
