How does paternity testing work?

Our DNA paternity testing works by comparing a child’s DNA profile with that of an alleged father (and often the mother as well). Because a child inherits half of his or her DNA from each biological parent, such a comparison reveals whether the child may have inherited DNA from the alleged father who is being tested.

We prefer to have a sample taken from the mother of a child, but we can test without this. Personal DNA paternity tests are done purely for your own information. For this reason, we will provide you with a kit for you to collect the swab samples at a time convenient to you. You can then drop them off back at our Biomedical laboratory location for the required analysis and we will email out a report which will confirm the likelihood of paternity.

What type of paternity test should I use?

If you need a test for your own knowledge of whether or not an alleged father is the true biological father of the child, then you can order a Personal DNA paternity tests kit, so you can take the sample yourself at your own convenience in your home and send it off to our laboratory for analysis.

This test is still extremely accurate, but it cannot be used for legal reasons because the sample has not been taken by someone impartial. If you need to use the test in legal proceedings, such as in court or for the Child Support Agency, then you will need a legal paternity test, which we can also provide.

We can also provide non-invasive prenatal testing if the baby has not been born yet. Much like a legal test this cannot be self-administered and a medical professional will need to take a blood sample, which can then be analysed by our laboratory to determine paternity.

We can also provide Y chromosome testing if the father is not available for any of the paternity tests, using another male family member from their side of the family. However, if the father is available, we highly recommend that the test is performed with the alleged father whenever possible.

What type of sample is used for paternity testing?

The sample required is a cheek swab (Buccal Swab), which can be collected by rubbing the swab on the inside of the mouth against the cheek area.

What is the difference between a Personal DNA paternity test and a Legal (or court approved) paternity test?

A Personal DNA paternity tests means that the paternity test can be self-administered at home using one of our kits that we will send to an address of your choice. It can be used for your own knowledge and peace of mind, but as the samples will have been collected by you (self-administered) it cannot be used in legal proceedings.

It will not be admissible in court, as proof as paternity for the Child Services Agency or for immigration purposes. It is still an extremely accurate form of testing and if you only need it for your own knowledge then it is a more affordable solution to determining the paternity of a child.

A ‘court approved test’ is a test that can be used as proof of paternity in legal cases. The difference here is that the sample will have been collected by a third party, who can certify that the person who is required to be tested is definitely the person who is actually being tested and that all the required procedures are followed during the sample collection process.

Is the test confidential?

Our testing is 100% confidential!

We follow strict procedures from start to finish with all of our sample collection. We will not disclose results or personal information to third parties and we password protect all of the data so we will only discuss any details of the testing with those who are entitled to know (on receipt of correct passwords or answers to unique security questions).

At what age can the child be tested for a paternity test/can you do prenatal paternity testing?

A paternity test can be conducted with a child of any age. There is no minimum age requirement and the procedure is totally painless. We can also test the paternity of a child before they are born. We can perform non-invasive prenatal testing to determine the paternity of the baby. However, the mother will need to have been pregnant for at least 9 weeks before this test can be conducted. Please consult your Doctor.

Does the mother have to give a sample?

It is not necessary for the mother to provide her sample. We can perform the DNA test without the mother’s sample however it is not something we recommend as half of the child’s DNA is shared with the mother.

This means when we perform a DNA test without the mother’s sample you do run the risk of obtaining an inconclusive result if we come across an anomaly such as a mutated allele, in this case we would require the mother’s sample anyway which would cause delays in the process.

Why do we have to test the mother?

Half of the child’s DNA comes from the mother and the other half from the father. When the mother is included it is possible to identify which of the child’s DNA comes from her, leaving the paternal DNA to compare against the alleged father. When the mother is included in the testing it provides much greater certainty and conclusively of the results.

If the mother is not included it can reduce the CPI (Combined Paternity Index) and probability so much so that the result is no longer conclusive or definite, in which case we would require the mothers sample anyway. This leads to the process taking longer and delays to the result. It is ultimately in your best interest to include the mother in the testing from the start.

How much does it cost to test an additional Father or Child sample?

It depends on if it is a legal or a personal paternity test. See prices below:

Personal DNA Paternity Test:

Additional Father/Child $19,500.00

Legal DNA Paternity Test:

Additional Father/Child $21,000.00

Where can I buy a paternity test?

You can purchase our simple-to-use Personal DNA paternity tests for peace of mind today at any of our DNA collection sites.

How accurate are the results?

The results of DNA paternity testing are extremely accurate, especially if the testing also involves the mother (see above). No paternity test available can claim 100% probability of paternity but this does not mean that they are not accurate.

We can proudly state that our paternity testing can determine a probability of paternity of over 99.99%. Our results ARE about as accurate as it gets, at determining the probably of paternity. But it is important to consider the difference between words such as ‘conclusive results’, ‘probability of paternity’ and ‘accuracy’.

To clarify, anywhere that claims that it can give 100% probability of paternity (rather than ‘accuracy’) may be being more than misleading. Be sure to look for the percentage of probability as well as the accuracy as all companies will claim to be accurate.

Our referral partners are an ISO17025 and CAP accredited laboratory, which means it meets the highest standards having been independently assessed by the sole national body recognised by the government for international quality requirements for laboratories.

What is the turnaround time for the DNA test?

Turn-around time is 5 -10 working days from the time of collection of samples, unless RUSH service is requested and this must be written on the envelope (e.g., RUSH 2 -day service).
