Avuncular Test
This test determines the biological relationship between an alleged aunt or uncle and their niece or nephew. This is often used when a parent is unavailable for DNA testing, such as in paternity cases.
”An avuncular test will show the likelihood (expressed as a percentage) that the two people tested are related. This percentage is called a probability of relationship. Aunts and uncles will share around 25% of their genetic makeup with their nieces or nephews; however, in some cases the amount of common DNA may be much higher or much lower. The higher the probability, the more likely it is that the tested people are in fact biological relatives. Further to this, your result will also express the avuncular index. If this index is more than 1.00 then the tested parties are probably genetic relatives. If the avuncular index is below 1.00, then it is likely that they are unrelated.“
Aunt & Uncle Test
Aunt/uncle relationship test offered by Biotel DNA Kenya is used to confirm the biological relationship between alleged relatives. This test seeks specifically to establish whether aunts and/or uncles are genetically related to their nieces and/or nephews.
Male individuals seeking to confirm a paternal uncle-nephew relationship can utilize a Y chromosome test, which generally provides more accurate results than traditional aunt/uncle DNA testing. Additionally, Y chromosome test results are typically available within a shorter timeframe, usually 5-7 business days.
- DNA samples are collected from both individuals (alleged aunt/uncle and niece/nephew) through a simple cheek swab.
- The DNA samples are analyzed in a laboratory to identify specific genetic markers.
- The genetic profiles of the two individuals are compared to determine the likelihood of a biological relationship.
