Use of test


This test assesses up to 24 highly variable regions of the genetic code between mother, father and the fetus to determine whether the fetus is biologically determined to be from those parents.


A man can be excluded with 100% certainty of being the biological father of the fetus. If the man is not excluded, then with DNA testing, the probability of him being the father will be reported with a minimum likelihood of 99.95%.
