Aunt and Uncle tests are done instead of, but do not replace, a paternity test. Results reflect a statistical likelihood, but not the highly accurate results that would be achieved through a paternity test using the alleged father’s DNA.
More accurate results can be achieved by adding a DNA sample from the mother of the child, allowing our analysts to view a full range of DNA.
Results indicating a probability of greater than 80% will usually indicate a biological relationship, and results indicating a probability of less than 20% indicate that a biological relationship does not exist.
Male only DNA Tests
If the participants providing samples are only male, a Y Chromosome Test is advised. This is the best way of confirming a paternal bloodline, as males from the same paternal line will have a copy of the same Y chromosome. If results indicate that two (or more) males share the same Y chromosome, then they will also share a paternal relative.
As with any relationship, the samples of both parties (usually the mother) is highly recommended in order to obtain the best results outcome without the need to resample or recollect DNA. This test will indicate the probability of the relationship. Proable indicators will indicate that there is a 20% or below that there is no relationship; whilt a positive result will indicate a 80% or higher chance of biological relationship.
Notes for Y Chromosome
Testing of male relatives; we highly recommend that those individuals included in the test are Y chromosome (male descendants or relatives) in order to match the same paternal line. Please ask us via our chat facility or contact us page to know more.
