What does the DNA test result look
like? |
|
Our test results give you a detailed
description of how the test is conducted, what the results
are, and what those results mean. We take great care in
making our tests both easy to understand and scientifically
sound. Below is a sample version of our DNA Paternity test
results showing "EXCLUSION", i.e. exclude the alleged
father
being the biological father, so you have an idea of what to
expect when you receive them, and you
can better understand
how we've arrived at the results. |

Results: |
- John Lee is excluded from
being the biological father of Mary Lee.
- Combined Parentage Index
(CPI): approximately 0
- Probability of Paternity:
approximately 0.0%
|
|
Summary and Interpretation of Results: |
Based on
the results from the 15 genetic systems (loci) shown
below, John Lee is
excluded from being the
biological father of Mary Lee because they only
share alleles
at 4 of the 15 loci analyzed. A CPI
greater than 100, representing a Probability of
Paternity greater than 99%, is required in order to
not exclude the alleged father from being the
biological father. The CPI is approximately 0 for
this case, resulting in an approximate 0.0%
Probability of Paternity for this case. |

In this example, the alleged father is being "excluded"
as possible biological father.
At each locus, matches between alleged father and child
are identified. For each match, a Parentage Index
is
calculated based on the frequency of the allele within the
population. If there are matches within all loci,
the
Combined Parentage Index (CPI) is calculated and a
Probability of Paternity is determined. If there are 2
or
more locus mismatches then the alleged father is 100%
excluded as the biological father.
If you look at the locus D7S820 in the results above, the
mother and child share the allele 8. However, the
alleged
father and child do not share alleles 10 and 12. In total,
the alleged father and child only share 4 out
of 15 tested
alleles. Therefore, the alleged father cannot be the
biological father of the child.

Locus = the name
or generic code given to identify each location tested on
the DNA strand.
Allele = also
known as marker represents the number short tandem repeats (STR)
from each parent passed
down to the child.
Parentage Index (PI) = represents
the relative uniqueness of a match between alleles. The
higher the number, the more unique the match.
Combined Parentage Index (CPI) =
the product of all parentage indices. The higher the number
of CPI, the stronger the probability of a biological
relationship.
Probability of paternity = the
percentage of paternity. In the exclusion DNA paternity
result like above,
probability of paternity = 0.00% excludes
the alleged father from being the biological father of the
child.
