In almost all paternity cases, if the alleged father is the true
father, all 15 genetic markers will match those of the child
(the 16th genetic marker is used to confirm the sex of the
person). This is referred to as “no exclusions.” *We guarantee
that in such cases (testing the mother, child, and alleged
father), our tests will yield Probabilities of Paternity of more
than 99.999%. This is a 1000 times more than the 99% required by
the AABB (American Association of Blood Banks). Such extremely
high probabilities mean that you can have the peace of mind that
the tested father is the true father. If we fail to exceed
Probabilities of Paternity of 99.999% in cases of no exclusions,
we will refund the cost of the test. Another way to interpret a
minimum Probability of Paternity of 99.999% is that the chance
of a wrong conclusion (i.e., that the biological father is not
the man tested) is at worst 1 in 100,000. Typically in our
tests, these odds are 1 in millions, or even higher.
It is possible
for the tested father to be the true father and still have one
or even two exclusions (mismatched genetic markers) because of
mutations in the father’s DNA. In most cases of one exclusion,
the Probability of Paternity will still be very high (greater
than 99.9%), although this cannot be guaranteed. Cases of two
exclusions may be ambiguous and require further testing of
additional genetic markers. Cases of three or more exclusions
result in the conclusion that the tested father is “excluded” as
being the father of the child. This results in a probability of
exclusion of 100%.
If a test
includes only one parent and the child, we cannot guarantee a
minimal probability of parenthood. In most cases, however, these
probabilities are greater than 99.99%.
*This guarantee assumes that the persons tested
are each members of one of the following races: Asian-American,
African-American, Caucasian-American, or Hispanic-American. This
is because the probabilities of paternity depend on the
frequencies of different genetic markers in databases based on
these races. We can still perform paternity tests with family
members from other races, but calculations become more
conservative and may possibly result in probabilities of
paternity of less than 99.999%, although this is unlikely if all
15 genetic markers in the father match. |
