The result conclusion will state one of the following phrases. What does not excluded on a DNA test mean? It means the evidence submitted (genetic testing samples) to the lab whether for legal or for peace of mind purposes supports the assumed alleged father is excluded as the biological father. Since the biological mother is known, including her will eliminate half the DNA the child carries, strengthening the matches between the father and child (and getting a probability of 99% or higher). Results show one of two determinations. DNA is DNA, whether it comes from a blood sample or a swab, its all the same.

My best guess (based only on the 99.9% number you give) is that he IS the father of the girl. you can see that the potential father does not share a marker with the child and is therefore excluded from paternity (i.e., he cannot be the father).

I had a legal test done by child support. Pneumonia can be caused by multiple types of, Read More Chest X-Ray: Pneumonia Vs NormalContinue.

It is definitely not unusual for a mother and father to share some of the same alleles at a particular locus. A negative result does not exclude the presence of a myeloproliferative neoplasm or other neoplastic process. That way, you can be sure the right DNA is submitted for testing.

Sometimes, the differences between the alleged father and the childs DNA profiles are not unique enough on their own to determine a conclusive answer (either 0% or a probability higher than 99%). Back in 1994 my now husband was court ordered to do a DNA test, as was his brother (same mother and same father the brothers have). It is highly likely that they share a half-sibling relationship. In paternity testing, any result above 0% and under 99% is considered to be inconclusive by accredited DNA testing laboratories. For example the father might have an STR that repeats 8 times and the childs STR repeats 9 times. And yes, it is possible that the biological father is a close relative of the man who was tested. It a crazy cause he has me second guessing myself. However, if two possible fathers are close relatives, such as brothers, they share much of the same DNA. Would this make them related for sure or could someone else be her father? It is not unusual at all for people who dont share a biological relationship to have alleles in common at certain markers. the alleles do not match) at two different genetic markers. Father has 4 children from first wife who has died. Each marker contains two genes: one from the mom and one from the dad.
