Grandparent DNA test

DNA testing of grandparents can be very helpful in establishing relationships. Whenever a child's alleged father is not available for testing, the next best type of test is a DNA test of grandparents using both presumed biological parents of the father. With the two alleged biological parents of the father involved, we basically have 100% of the alleged father's DNA. Generally, we can compare the child in question to the two presumed paternal grandparents without testing the mother. If a test containing the two biological parents of the alleged father is inconclusive, which is rare to begin with, the child's mother can be added to the test to reinforce the result. If and when the alleged father's biological parents are not available, we can use one. By comparing a grandparent, grandfather or grandmother, to the child, we prefer to add the mother of the child in the case initially to mitigate the likelihood of an inconclusive outcome. If the child's mother is not available, we can test only a grandparent and a child, but the probability of an inconclusive outcome is much higher.

A  is useful at all times when the alleged father of a 
child is not available for testing or refuses to be involved in the test. If you 
do a DNA test for legal or paper reasons, such as survivor benefits in the 
case of a deceased father, first check that the organization you are working
 with will accept the results of a DNA testing of grandparents. In some
 cases, they will not.

for you.
