International)
- Texas Department
of Public Safety.
How long does
it take to complete a forensic case?
The length of time to complete forensic
cases can vary with the type and number of samples, but usually takes
approximately 3-4 weeks for standard processing. RUSH processing is
available.
What samples can I send for forensic DNA testing?
Success
with different samples varies so it is important to talk to a Forensic DNA Case
Consultant to find out more information.
What forensic services does DNA Profiles of Amercia offer?
We provide DNA analysis of evidentiary material,
evidence screening, semen detection, blood detection, infidelity testing,
criminal paternity testing, expert witness testimony, consultation, and legal
support.
What platform and testing systems does you testing lab
use?

Who will help
me with case issues?
For non-technical questions or case status updates, you
may call one of our Forensic DNA Case Consultant at his/her direct
toll-free number. Our Laboratory Director and Forensic Analysts are also

outsource a larger volume of cases, we offer discounted pricing depending on the
number of cases submitted.
How can DNA Profiles of America assist with
reference sample collection?
We can provide you with buccal swab sample
collection kits, and we can coordinate sample collections at any one of our
authorized collection facilities throughout the U.S., and in various locations
throughout the world.
What is your chain of custody procedure?
We
provide a chain of custody form that should be completed with each sample
submission. It contains all necessary information for proper chain of custody,
which is required for legal use as evidence.
Does your testing facility
perform its own statistical analysis of the data?
Yes.
What software
does your lab use for analysis?
We use ABI Genemapper software for
data analysis. We also use proprietary enterprise software to
login, track samples, perform automated quality control checks, and for
facilitated report writing. Our system is written in SQL server.
What
quality control does your lab perform for data analysis?
All
procedures are validated in-house following DNA Advisory Board guidelines. Our
automated quality control checks include checks on the allelic ladder, control
DNA, and the in-lane size standard.
How is expert witness testimony
handled?
Our professional staff is available to testify with advance notice
on a fee-per-day basis. The client should arrange for the transportation and
lodging of our expert, and pay for incidental expenses. You may pay a per diem
for incidentals, if that is preferable.
Does your lab perform
Y-STR testing?
Yes, we offer ABI
Y-filer Y-STR testing.
Does your lab perform mitochondrial DNA testing?
Not in house, but we
routinely outsource it to labs accredited for such testing.
When is it
appropriate to use Y-STR testing?
If an evidence sample is predominantly
female, but with very few male cells, Y-STR testing may reveal a male DNA
pattern. Additionally, if there are multiple male contributors to a sample,
Y-STR testing may help to delineate the male contributors.
Can you
determine the sex of the person tested?
Yes. Amelogenin (a sex-specific
marker) is part of our standard forensic DNA profile.
Does your lab run AmpliType DQA1 (DQ Alpha), AmpliType PM (polymarker), or
RFLP testing?
Because these are not routinely used in forensic casework any
more, we do not perform the these tests.
Does your lab
participate in proficiency testing programs?
Yes, our lab complies
will all accreditation requirements for external proficiency testing. A summary
of our proficiency results is available upon request.
