These
tests can be used in addition to any of
our DNA tests when the circumstances call
for a more in depth test than what is usually
required.
Our DNA tests analyse 16 genetic
locations – this is the GOLD standard
for these tests.
However, it is small possibility
that in certain
scenarios an inconclusive result may be
given.
Examples of these scenarios are:
Paternity
Analysis – The
two alleged
fathers in
a case are
full Siblings. If only ONE alleged father
is tested and the analysis demonstrates
ONE mismatch
in the sixteen, a further study will be
required to establish whether this mismatch
is due to mutation or because the other
brother is the true biological father.
The same can be applied to potential mothers
in a Maternity test if they are full biological
sisters
This is rare but must be considered
in these unusual
situations.
Sibling/Grandparent
Analysis – As
explained on
the individual
test pages, the fewer test participants,
the more likely
these tests
will yield
inconclusive
results. It is still a relatively rare
occurrence but to achieve the most definitive
answer possible in certain circumstances
e.g. half Sibling
test with no known parent, it would be
recommended.
What does this test do?
This
test will analyse
a further 4
genetic locations. So the result
will then be
based on 20 genetic locations instead of
16. This increases statistical strength
vastly.
Please Note: The DNA stored in
the laboratories
will be used for the extended study. There
will be no
need for Clients to revisit the clinic
or be sent reswabs!!
The likelihood of
another inconclusive
result at this stage is virtually NIL for
any of the above tests in any scenario.
In the extremely unlikely event that this
should happen, there is a further extended
test that is capable of analysing a further
14 genetic locations. However, this is
a very costly test and you should ring
and discuss this with a scientific advisor,
should the event ever arise.
Options and
cost!
The cost
of the extended
study includes the first 3 people in a
test. Further individuals will be charged
at the additional
persons rate.
If your case has a raised
likelihood
of an inconclusive result, you will be
informed of this so that you are aware
of all facts. In some cases it may be possible
to involve more people in a test and thus
improve the chance of conclusive results.
This can be discussed with a scientist
on 0800 032 5945
If further participants
are not available,
you can choose
from the following:
- Proceed
with the
standard test and see
what the
intial result is.
Afterall
it may be fine.
- Order
the extended
study
straight away to avoid the delays
caused
by retesting.
Protocal for
extended study.
Inconclusive
Standard test:
If you opt to try the
standard test
first and receives
an inconclusive
result, you
will be contacted
directly by
a scientist
to explain
the outcome
and how much information can be taken from
that initial test.
If you decide to order
the extended
study, the fee for the test should be forwarded
directly to the laboratory. Once received
the test will be performed.
This test will
take a further
7 – 9
working days.
Clinic ordered
Extended Study: If a Client
decides to
order the extended
study straight
away to avoid
possible delays,
then the cost
of the extended
study will be added to
the cost of
the test being
undertaken.
Remember the cost of an extended study
includes the
first 3 people in a case. Additional people
will be charged at the additional persons
rate. All initial
participants need to take part in the extended
study for it to be effective.
