Frequently Asked Questions - Paternity DNA Testing
Paternity DNA testing is a scientific method used to determine whether a man is the biological father of a child. It compares the DNA profiles of the alleged father, the child, and sometimes the mother, to establish biological relationships.
Paternity DNA testing involves collecting a sample of DNA from the alleged father, child, and sometimes the mother. The samples are usually obtained through a simple and painless process, using buccal swabs, where a cotton swab is rubbed inside the cheek to collect cells. The DNA samples are then analysed in a laboratory, comparing specific regions of the DNA to establish paternity.
Paternity DNA testing is highly accurate and can provide conclusive results. In most cases, it can establish paternity with an accuracy of 99.9% or higher, providing strong evidence of a biological relationship.
Yes, paternity DNA testing is widely accepted and recognized as reliable evidence in legal matters. The results can be used for various legal purposes, such as child custody, child support, immigration cases, and inheritance claims. However, it’s important to follow the legal requirements and guidelines of the jurisdiction where the testing is being conducted.
In general, you can expect to receive the results within 1 to 2 weeks from the time the laboratory receives the DNA samples.
Yes, it is possible to perform a ‘peace of mind’ paternity DNA test without the mother being tested. However, for legal paternity testing, we include the mother’s DNA sample in the testing process to provide more accurate and conclusive results. If the mother’s sample is not available, a testing laboratory can still analyze the DNA of the alleged father and child to determine paternity.
Yes, if the child is a minor we require the mother to attend and provide consent for their child to be tested. If the child is an adult, they are able to provide their own consent.
Yes, see the section on non-invasive prenatal paternity testing (NIPPT).
There is no age limit for paternity DNA testing. Whether the child is an infant, child, or adult, paternity can be determined through DNA analysis at any stage of life.

Legal DNA Testing: Legal DNA testing is performed to establish a relationship for legal purposes, such as child custody cases, child support claims, inheritance disputes, or immigration applications. The results obtained from legal DNA testing are legally admissible and can be used as evidence in court proceedings or official documentation.
Key features of legal DNA testing:
- Chain of Custody: Legal testing requires strict adherence to a chain of custody process. This ensures the integrity of the DNA samples and prevents tampering or substitution. Trained professionals typically collect the samples, verify the identity of the individuals being tested, and maintain proper documentation throughout the process.
- Accredited Testing Laboratory: An accredited reputable testing laboratory, under recognised quality standards and guidelines, conducts legal testing. The laboratory’s accreditations and certifications help establish the reliability and accuracy of the test results.
- Identification Verification: Legal testing requires individuals to present valid identification documents to verify their identity. This helps ensure that the correct individuals are tested and eliminates the possibility of fraudulent or unauthorised testing.
- Legal Documentation: Legal testing results are accompanied by a detailed and official report that includes the names and identifying information of the tested individuals, the testing methodology used, the laboratory’s information, and a statement of the probability of relationship. These documents are typically required for legal proceedings or official applications.
Peace of Mind Testing: Peace of mind testing is conducted for personal knowledge and reassurance without legal implications. It is often for individuals who want to confirm the biological relationship between a child, potential parent or kinship for personal reasons, curiosity, or emotional closure.
Key features of peace of mind testing:
- Convenience: Peace of mind testing is designed to be easily accessible and cost less.
- Privacy: Peace of mind paternity testing allows individuals to maintain their privacy as the testing process can be conducted without legal authorities. The results are typically shared only with the tested parties.
- Non-Legal Nature: Peace of mind testing does not have the same legal weight or validity as legal testing. The results are meant for personal knowledge only and cannot be used as official evidence in legal matters.
Please check with the Clinic Coordinator to confirm if Legal or Peace of Mind testing is available and what is required.
Frequently Asked Questions - Non-Invasive Prenatal Paternity Testing
Non-invasive prenatal paternity testing is a method used to determine the biological relationship between a potential father and an unborn child during pregnancy. Unlike invasive prenatal testing methods, such as CVS or amniocentesis, non-invasive testing carries no risk to the fetus or mother.
Non-invasive prenatal paternity testing analyses cell-free fetal DNA (cffDNA) present in the mother’s blood during pregnancy. The test compares the DNA of the potential father with the fetal DNA to establish paternity. This can be done as early as the 8th week of pregnancy.
Non-invasive prenatal paternity testing is highly accurate, with a reliability of 99% or higher in determining paternity. However, it’s important to note that the accuracy may vary depending on the quality and quantity of the fetal DNA in the mother’s blood.
Non-invasive prenatal paternity testing offers several benefits, including:
- No risk to the fetus or mother: The test poses no physical harm or risk of miscarriage compared to invasive methods.
- Early detection: Testing can be performed as early as the 8th week of pregnancy, providing earlier results compared to traditional methods.
- Simple procedure: The testing process only requires a blood sample from the mother and from the potential father.
Non-invasive prenatal paternity testing has a few limitations to consider:
- Limited availability: blood samples need to be taken by a specific collection centre and returned to the clinic to be couriered the same day. There are specific days for collection. Please check with the Paternity Co-ordinator.
- Cost: Non-invasive prenatal paternity testing is considerably more expensive than postnatal paternity testing.
Accuracy limitations: The accuracy of the test depends on the quality and quantity of fetal DNA in the mother’s blood. In rare cases, there may be insufficient fetal DNA for a conclusive result.
Yes, non-invasive prenatal paternity testing can determine paternity even when multiple potential fathers are involved. The DNA profiles of each potential father are compared with the fetal DNA to establish paternity. However, it’s important to provide DNA samples from each potential father for accurate results.
No, non-invasive prenatal paternity testing requires the knowledge and consent of the pregnant mother. The test relies on analyzing the fetal DNA present in the mother’s blood, so her participation is essential.
Although very accurate it is not admissible in court and will need to be repeated after the baby is born using a legal paternity testing process.
Generally, results are available within 2-3 weeks from the time the laboratory receives the blood sample from the mother and the potential father’s DNA sample.
Yes, non-invasive prenatal paternity testing can determine the sex of the unborn child. The test analyzes specific DNA markers, including those related to sex chromosomes, allowing for the identification of the fetal sex. This is a separate test and cost.
Non-invasive prenatal paternity testing can be performed for multiple pregnancies, including twins or higher-order multiples. The accuracy of the test may be affected by the presence of multiple fetuses.
Non-invasive prenatal paternity testing typically requires a blood sample from the pregnant mother and a DNA sample from the potential father. Additional information or documentation, such as confirmation of pregnancy viability and gestation (weeks), is required.
Non-invasive prenatal paternity testing cannot be performed if the potential father is deceased, as it requires a DNA sample from the potential father for comparison.
Frequently Asked Questions - Maternity Testing
Maternity testing is a scientific process used to determine whether a woman is the biological mother of a child. It compares the DNA profiles of the alleged mother and the child to establish the biological relationship.
Maternity testing involves collecting DNA samples from the alleged mother and the child through a simple and painless process called buccal swabbing, where a cotton swab is rubbed inside the cheek to collect cells. The DNA samples are then analysed in a laboratory, comparing specific regions of the DNA to establish maternity.
Maternity testing is equally accurate as paternity testing. It can establish maternity with a high level of accuracy, usually 99.9% or higher, providing strong evidence of the biological relationship between the alleged mother and the child.
Yes, maternity testing is widely accepted and recognized as reliable evidence in legal matters. The results can be used for various legal purposes, such as child custody cases, immigration cases, and inheritance claims. However, it’s important to request a legal maternity test as opposed to a ‘peace of mind’ testing process.
Yes, maternity testing can be performed without the alleged father’s involvement. The test focuses on comparing the DNA profiles of the alleged mother and the child to establish maternity. However, including the alleged father’s DNA sample can provide additional evidence and strengthen the results.
The turnaround time for maternity test results can vary depending on the testing provider and the specific type of test chosen. In general, you can expect to receive the results within 2-3 weeks from the time the laboratory receives the DNA samples.
Yes, prenatal non-invasive prenatal maternity testing can be conducted.
There is no age limit for maternity testing. Whether the child is an infant, child, or adult, maternity can be determined through DNA analysis at any stage of life.
We provide reputable testing and adhere to strict confidentiality policies to ensure that the test results and personal information of the individuals involved are kept confidential and are only accessible to authorized personnel.
Frequently Asked Questions - Kinship DNA Testing
Kinship DNA testing is a type of genetic testing used to determine the biological relationship between two or more individuals who are presumed to be related, such as siblings, grandparents, aunts/uncles, or cousins. It compares the DNA profiles of the individuals to establish the degree of genetic relatedness.
Kinship DNA testing analyses specific regions of the DNA of the individuals involved to identify shared genetic markers. The more genetic markers shared between individuals, the stronger the evidence of a biological relationship. The testing process involves collecting DNA samples, usually through buccal swabs, and comparing the DNA profiles in a laboratory.
Kinship DNA testing can provide accurate results, but the degree of accuracy may vary depending on the closeness of the relationship being tested. Testing for immediate family relationships, such as full siblings or parent-child, can have high accuracy levels similar to paternity or maternity testing. Testing for more distant relationships, such as cousins, may have a slightly lower accuracy rate due to the reduced amount of shared genetic material.
DNA testing can be used to establish a variety of kinship relationships, including sibling relationships (full or half siblings), grandparent-grandchild relationships, aunt/uncle-niece/nephew relationships, and cousin relationships. The specific testing options and accuracy may vary depending on the testing provider and the degree of relatedness being investigated.
Yes, kinship DNA testing can be used for immigration purposes to provide evidence of biological relationships between family members. Many immigration authorities accept DNA test results as supporting evidence for visa applications or family reunification cases. It’s important to consult with the appropriate immigration authorities and follow their specific guidelines and requirements and discuss these requirements with the clinic co-ordinator.
In general, you can expect to receive the results within 2-3 weeks from the time the laboratory receives the DNA samples.
Kinship DNA testing can provide information about the likelihood of a specific kinship relationship, but it cannot determine the exact degree of relationship with absolute certainty. The results can indicate the probability of a relationship, such as a high likelihood of full sibling-ship or a lower likelihood of cousin-ship. However, the precise degree of relationship may require additional information and analysis.
We are reputable testing providers and prioritise confidentiality and ensure that the test results and personal information of the individuals involved are kept confidential.
Frequently Asked Questions - Twin DNA Testing
Twin DNA testing is a type of genetic testing used to determine whether individuals are identical twins or fraternal twins. It compares the DNA profiles of the twins to establish their genetic relationship and determine if they share the same genetic material.
Twin DNA testing analyses the DNA profiles of twins to determine the degree of genetic similarity between them. It involves collecting DNA samples from both twins through buccal swabbing or a blood sample from the mother if pregnant (see section below). The DNA samples are then compared in a laboratory to identify genetic markers and determine if the twins share identical DNA (indicating identical twins) or have different DNA profiles (indicating fraternal twins).
Yes, twin DNA testing can determine whether twins are identical (monozygotic) or fraternal (dizygotic). By comparing the DNA profiles of the twins, the testing can establish whether they share the same genetic material, indicating identical twins, or if their DNA profiles are different, indicating fraternal twins.
Twin DNA testing is highly accurate in determining whether twins are identical or fraternal. The accuracy rate is typically very high, exceeding 99%. The testing relies on analysing specific genetic markers and variations to establish the genetic relationship between the twins.
Yes, twin DNA testing can be performed before birth. Non-invasive prenatal testing through a specific laboratory can determine zygosity and also check the fetus’ chromosomes. This can be performed from 9 weeks gestation.
No, twin DNA testing cannot determine which twin is the older or younger sibling. Twin DNA testing focuses on establishing whether the twins are identical or fraternal based on their genetic relationship. It does not provide information about the birth order or chronological age of the twins.
The turnaround time for twin DNA testing results can vary depending on the testing requested, pre – post birth. In general, you can expect to receive the results within a few weeks from the time the laboratory receives the DNA samples.
