Paternity DNA Testing for Georgia Residents

Why consider DNA testing in Georgia?

Parents, guardians and custodians of children have good reasons to want to know the legal parents of a child. In some cases, multiple parties might want full or partial custody of a child or visitation rights.

There are a lot of reasons why paternity testing is important, even when custody is not an issue, the courts must often set financial guidelines for the child’s support. In the case of a severe illness, knowing the ethnic heritage of both parents is important in helping diagnose potential diseases and conditions that can be passed genetically among people of a specific ethnicity.

Whatever your reasons for needing a DNA paternity test, you can save time and money by knowing if your test is legally admissible in court. While different states might have different rules and regulations, knowing the basics of court-recognized DNA tests will help you get the right test you need the first time.


Georgia On-Site Lab Testing is committed to the pursuit of quality and make every effort to ensure that their paternity testing is performed in a quality-centered environment.

Georgia On-Site Lab Testing, paternity testing division and study division, partners with accredited laboratories in several organizations including the American Association of blood banks(AABB), the American Society for Histocompatibility and Immunogene (ASHI), and the College of American Pathologists (CAP).

Specimen Collection:

Georgia On-Site Lab Testing uses a variety of methods for specimen collection. The most common method is the non-invasive buccal swab specimen collection. This Method is performed by simply swabbing the inner facial cheek. Georgia On-Site Lab Testing, buccal swab collection kit is color-coded (swabs, labels, and envelopes). In some cases, a blood specimen may be required; however, the non-invasive buccal swab is the primary collection method.

Paternity / Maternity Testing:

Georgia On-Site Lab Testing has been a leader in conducting genetic marker testing for parentage and immigration evaluations. Georgia On-Site Lab Testing expertise includes maternity, sibling, and grandparent testing as well as reconstruction cases, which assist in determining paternity without the presence of the parent in question, either father or mother. Georgia On-Site Lab Testing is contracted with the leading-edge genetic system laboratories in performing paternity testing. The DNA test used at Georgia On-Site Lab Testing are extremely reliable with an average probability of paternity of 99.9%

Most Common Questions in Parentage Testing:

Q: Are genetic test valid when performed on a child under six months?
A: Yes, as long as certain test are avoided. The American Association of Blood Banks (AABB) specifically states that children under six months of age may not be tested for the serum proteins Gm and Km. Georgia On-Site Lab Testing does not perform these tests. Other tests can be accurately performed on children under six months of age, including red cell antigens, leukocyte antigens (HLA), and DNA.

Q: Is there a six-month age requirement for infants?
A: No, The six-month delay was a common procedure because of the difficulty of drawing blood from small infants and due to the AABB requirements stated above. However, buccal swab specimen collection has eliminated the difficulty of drawing blood.

Q: If a child is under six months, can DNA testing be done using a specimen other than blood?
A: Buccal swabs or cord blood collection at birth can be used and allow for rapid and reliable testing regardless of age.

Q: How does a buccal swab sample differ from a blood sample?
A: For purposes of identity testing, there is no difference in DNA derived from buccal swabs or blood.

Q: Are you collection saliva for testing when a buccal swab is done?
A: Although some saliva is contained on the buccal swabs, one is actually collecting epithelial cells off the cheeks inside the mouth (buccal cavity).

Q: Won’t the buccal swabs be contaminated since they are collected from the mouth?
A: The DNA testing performed is not affected by the DNA of bacteria, common foods, tobacco, or toothpaste, etc.

Q: What are the procedures to prevent a mismatch of samples?
A: Good laboratory practices that incorporate exclusion confirmation and duplicate testing if independent specimen preparations help prevent and detect mismatched specimens. Buccal swab collection is performed using different colored swabs for the mother, child and alleged father to minimize specimen mishandling.

Q: How many test systems (loci) should be ran
A: The multiple genetic system selected for routine testing at Georgia On-Site Lab Testing exclude on average 99.99% of falsely accused men from paternity.

Q: Are any other tests, such as AIDS conducted at the time the genetic testing is performed?
A: No other test are performed.

Q: Why can’t a simple genetic test, conducted in a physician’s office, be used to determine paternity?
A: Genetic analysis is more complex than most physician office laboratories are Capable of handling.

Q: Can parentage be established for a deceased alleged father?
A: If blood or buccal swabs are swabs are collected from the alleged father at the time of death, and shipped immediately to the laboratory, standard testing can be performed. If the alleged father is deceased, his parents can be tested to determine whether they may be grandparents. An alternative is to generate paternity reports based on transplant list(such as heart, kidney or bone marrow) HLA typings, tissue specimens from previous surgeries, or blood types from medical records. Alleged father who die in motor vehicle accidents often have specimens collected for toxicology studies. Such specimens or tissue samples from autopsy, obtained from the coroner’s office, are successfully used to determine parentage. In addition, the body can be exhumed and a tissue sample removed for testing.

Q: Can paternity evaluation be done without testing the mother?
A: Paternity testing can be performed if the mother is not available although additional laboratory processing is necessary. The mother’s parents may also be tested to improve the statistical evaluation or confirm maternity.

Q: Will testing also show if the mother is excluded from maternity?
A: Although rare, several confirmed cases of non-maternity have been found during routine paternity testing.

Q: If the mother and the alleged father are related, does this make any difference in the testing?
A: No. When mother and alleged father are related, the testing is still valid.

Q: If two alleged fathers are related (brother-brother, father-son, or nephew-uncle), is the testing valid?
A: The laboratory must be informed of the circumstances, because it is possible for both men to have the same or similar genetic markers, even when DNA analysis is performed. Extended testing may have to be performed until one man is excluded. Related alleged fathers should be tested at the same time until one is excluded.

Q: Can reliable testing be performed when the parties are drawn at different times?
A: Specimens from parties being evaluated together for parentage testing do not have to be obtained at the same time. Specimens are maintained securely until all specimens needed for case resolution are received.

Q: How long are buccal specimens good for future testing?
A: At Georgia On-Site Lab Testing, we have had excellent results in testing buccal swabs over two years old. Based on the success of testing dried blood stains, we anticipate that dried buccal specimens will offer many years of stability.

Q:Can sources of specimens be different within a case, such as a buccal swab from the child and blood from the adult?
A: DNA testing can use different sources, except for persons who have had a bone marrow transplant, DNA markers are the same in all the body’s nucleated cells. Buccal swabs should be used anytime a person being tested has had a bone marrow transplant.
