The DNA test explained |
| DNA
(deoxyribonucleic acid) is stored
in all nucleated cells of the
body. This is where genetic information
is contained. Every individual
has their own unique genetic
sequence, making DNA testing
the ultimate choice for Human
Identification testing. |
| Cells
can be isolated from a variety
of samples such as saliva,
blood, hair etc. For more
information please click here. The DNA from these
cells can then be extracted
for analysis. |
| Each cell contains 46 chromosomes. Upon conception, a child inherits one half of their DNA from the biological mother & one half from the biological father. Therefore, parentage can be determined by 'matching up' genetic material to the child. |
When
a child’s DNA does not
match that of the alleged
parent, they are excluded with
an accuracy of 100%, as they
could not possibly be related.
When the child’s
DNA does match the alleged
parent, we can prove a probability
of 99.999% that they are the
true biological parent. 100%
inclusion would only be possible
if every male/ female in the
world was tested.
Other biological
relationships can be
determined by analysing the
amount of matches found in the
DNA of two (or more) individuals |

THE
TEST |
| Once
reaching the DNA Clinic laboratories,
cells are collected from mouth
(buccal) swabs or other forensic
samples. The DNA is then extracted
for analysis. The DNA is amplified & treated
with fluorescent probes. These
probes are detected by high-tech
lasers using state of the art
equipment. This produces a pattern
that is unique to each individual.
A child’s pattern will
'match up' to those patterns
generated by their true biological
parents. Half will match the
mother's sample and half will
match the father. |
| If
it is revealed that the patterns
of an alleged parent DO NOT match
that of the child’s, there
is zero probability that they
are the biological parent. |
