DNA Testing Services

What is DNA?

DNA (Deoxyribonucleic acid) contains the genetic instructions used in the development and functioning of all known living organisms and some viruses. A DNA molecule is where the long-term storage of information occurs, and is often compared to a set of blueprints, a recipe, or a code.

DATCS offers a variety of DNA testing services

Maternity DNA Testing

A test using buccal specimens (oral) of a child, father and supposed mother to establish the probability of maternity. People use DNA maternity tests to prove motherhood to resolve immigration issues, argue for custody and visitation rights, to verify the link between an adoptee and biological mother, and more.

Paternity DNA Testing

When the mother is included in the paternity test, the laboratories guarantee a minimum probability of 99.99% in a paternity test using buccal specimen of a mother, child, and putative father to establish the probability of paternity.

Grandparentage DNA Testing

This test requires one of the following combinations:

  • Mother, child, 2 Grandparents
  • Mother, Child, 1 Grandparent
  • Child, 2 Grandparents
  • Child, 1 Grandparent

Avuncular DNA Testing

Used to discover the probability of paternity by testing paternal family members.

  • Mother, Child, Aunt or Uncle
  • Child, Aunt or Uncle

Siblingship DNA Testing

A test using buccal specimen of two or more donors to establish the probability of siblingship.

Infidelity DNA Testing

  • Semen Screen of Evidence (includes screening of 1-2 stains)
  • Gender Screen of Evidence Quantifier + Y Quantifier
  • DNA Profile of Evidence
  • DNA Profile of Reference Sample (Buccal Swab)

Immigration DNA Testing

Paternity/Relationship test used for immigration into the United States is generally handled like a legal paternity/relationship test with a few exceptions. The sample collection kit must be sent directly from the laboratory to the U.S. Embassy or Consulate that is performing the sample collection of the beneficiary(s). The same laboratory must test both the petitioner and beneficiary(s). Our laboratory will handle shipment of the test kits to and from the country where you are working as well as shipment of the report to the consulate/embassy.

Human Remains DNA Testing

DATCS’s network of laboratory partners have a powerful range of analytical tools for the identification of DNA evidence in human remains.

Ancestry DNA Testing

Our laboratory has partnered with DNA Consultants to allow our customers to use existing autosomal profiles (the same profiles you obtain from a paternity test) for ancestry purposes.

Buccal Swabs vs. Blood DNA Testing

Questions? Contact Us Today!

The DNA in a person’s blood is the same as the DNA in their buccal cells, skin cells, tissue and saliva.

One common misconception is that DNA results generated from a buccal swab will not be as accurate or reliable as those from a blood sample. In reality, buccal samples are the method of choice for DNA collection and are actually more reliable than blood samples for patients who have recently had blood transfusions or a bone marrow transplant.

In these cases, the patient’s blood may contain DNA from the donor, thereby generating confounding or inaccurate conclusions.

Buccal Swab Advantages:

  • Fast and easy to perform
  • Painless and non-invasive
  • Suitable for a newborn
  • Does not require a phlebotomist
  • Samples do not require refrigeration
  • Does not require expensive shipping procedures and biohazard container
  • Reduced risk of exposure to blood borne diseases
  • More reliable than blood samples for patients who have recently undergone blood transfusions or a bone marrow transplant

Below is a list of accreditations, and licensures our laboratory holds:

  • AABB (formerly American Association of Blood Banks) accreditation for parentage testing
  • Clinical Laboratory Improvement Act (CLIA) License No. 34D0954530
  • College of American Pathologists (CAP) No. 13969-01
  • State of New York Department of Public Health licensure
  • Accredited to ISO/IEC 17025 by ANSI-ASQ National Accreditation Board/FQS

All Court Permissible Paternity testing requirements

  • An accredited laboratory
  • A non-biased collector
  • A legal chain of custody
  • Photo-identification
  • Exceptions

If a government issued photo ID or photograph cannot be obtained, either because the sample is from a deceased individual, a prenatal sample, an incarcerated individual or a sample provided by law enforcement officials, a signed affidavit attesting to the identity of the individual sampled may be supplied by the individual who performed or witnessed the sample collection, such as a doctor, coroner, corrections officer, third party, etc. Some laboratories may have a special form that can be filled out for these particular situations.
