Sibling DNA Testing

and Half Sibling DNA Testing

Sibling DNA testing, or half-sibling testing, can be performed with DNA samples from as few as 2 potential siblings. Testing more areas of DNA from each sibling means that your results are highly accurate. Also providing samples from any additional relatives such as a common mother, other siblings, an aunt or an uncle, further increases the conclusiveness of the test. This is due to the extra genetic information provided.


Sibling DNA testing starts at only $475 for two potential siblings.

    6.  “Sampler” means whoever takes the Sample.
  2. Application of Terms and Conditions
    1. The Order is an agreement between the Purchaser and ABTG. If a Nominated Person is included in the transaction the consumer warranties and exclusions are taken to bind that person. In other words that person becomes a Third Party to the Agreement, which is governed by these Terms and Conditions, subject always to the control of the Purchaser in relation to the dissemination and or use of the information provided. All other people who were involved in the test must look to the Purchaser for a copy of the information.
    2. These Terms and Conditions are to be read in conjunction with our Website Disclaimer and Privacy Policy.
    3. An order by the Purchaser shall constitute an offer for the test or service ordered. The offer is accepted when the purchaser signifies acceptance by activating the above “I Agree” button and then proceeds to make payment for the test or service. Or, in the case of phone orders, when the Purchaser verbally accepts the Terms and Conditions and then pays for the test or service. Only then is there a binding agreement between the Purchaser and ABTG.
    4. Acceptance of an order is at the discretion of ABTG. An offer will be deemed to have been accepted when ABTG commences work on the test or service ordered. However, in cases where full payment has not yet been received, ABTG will not be obligated to complete the test or service or provide results or a report until full payment has been received.
  3. Price
    1. Prices for standard services which are not listed on this website are listed in ABTG’s price list. Prices are available upon request.
    2. For more complex tests and services the price will be determined based on the extent of testing required, the level of complexity and the amount of work required. Please contact us to discuss your case and request a quote.
  4. Payment
    1. In cases where payment for a test or service is not required to be made upfront, a deposit shall be required to commence the test or service, and the remainder shall be payable within 30 days.
    2. Results and reports will not be released until full payment has been received. Late payments will delay the delivery of the service. Title in the results and reports of the test or service ordered remains with ABTG until full payment has been received.
    3. The Purchaser shall pay any costs incurred by ABTG due to late payment or failure to pay, including costs associated with the recovery of unpaid amounts due.
  5. Delivery and Turnaround Time
    1. ABTG provides the results/report of the test to the Purchaser and/or the Nominated Person. Written permission from the Purchaser is required in order to provide the results/report to other parties to the test, or their legal guardian if they are under 18.
    2. All standard shipping costs, including delivery of Sample kits, application forms and reports, are included in the price paid for the test or service.
    3. The majority of paternity test results will be ready within 5-9 business days from the time that we receive your Sample. However, ABTG will not be held liable for longer turnaround times and delays shall not be considered a breach of contract.
    4. The turnaround times for other tests and services vary according to the complexity of the case and level of work required. ABTG endeavours to provide all test results within a reasonable time frame. Please contact ABTG to enquire about the turnaround time for other tests or services.
    5. ABTG accepts no liability for delays in delivering the test or service caused by third parties or circumstances beyond our control.

  6. Purchaser's responsibilities
    1. The Purchaser confirms that the Purchaser and the Nominated Person are of legal age (of at least 18 years).
    2. ABTG has no control over the process of sampling. It is the Purchaser’s responsibility:
      1. to control the sampling, and secure the necessary Samples;
      2. to ensure that all Samples are obtained legally, ABTG accepts no responsibility for illegally obtained Samples, and
      3. The Purchaser assumes all risk in respect of any such conduct, and
      4. Indemnifies and holds harmless ABTG against all claims made against it in respect of such conduct.
    3. The Purchaser is responsible for promptly supplying any required Samples, completed forms or documentation. Delays in supplying these will delay the delivery of the test or service ordered. ABTG will not be held liable for such delays.
    4. The Purchaser agrees that testing and analysis shall be carried out using sufficient genetic material and  testing as deemed necessary by ABTG in order to obtain a reliable result for the ordered test.
    5. The Purchaser agrees to provide ABTG with all requested information. If the Purchaser fails to provide all requested information, they accept that this could result in a delay in the test or service, or inaccurate results. ABTG does not accept liability for the consequences of a failure to provide ABTG with all requested information. In particular, if the possible fathers may be related to each other you must inform ABTG.
    6. The accuracy of each paternity test is reflected by the stated percentage range in almost all cases. However, the Purchaser and Nominated Person accept that the stated figures are based on the typical paternity index, and that the percentage accuracy of individual results may occasionally fall outside of this range.
    7. Whilst every reasonable endeavour is made to provide the most accurate results possible, ABTG will not be liable for Samples failing to produce a DNA profile, or results producing a low level of accuracy, due to sampling errors, degradation of the Sample, or due to contamination errors caused by the Sampler.
    8. If the first set of DNA Samples do not provide sufficient DNA, or if there is a contamination issue that cannot be rectified, ABTG will send out an additional testing kit and re-perform testing and analysis. This may incur a fee. In the very rare cases where this still results in a low level of accuracy the Purchaser and Nominated Person shall accept this lower level of accuracy reported. ABTG will not be held liable for any delay in the delivery of the test or service due to retesting.
    9. In the case of certain rare DNA mutations it may not be possible to obtain results at an extremely high level of accuracy, in such cases the Purchaser and Nominated Person shall accept a test result of lower accuracy.
    10. The Purchaser accepts that all tests and test results are subject to the scientific limitations of the test used. ABTG shall not be liable due to further knowledge gained within the genetic testing industry.

    12. ABTG is not providing medical advice and is not a health service provider. 
    13. The Purchaser acknowledges that ABTG’s home kinship and home parentage (paternity and maternity) tests are for personal information and peace of mind only and are not legal tests. They are not intended for use in a Court of Law.
    14. All other tests and services offered by ABTG can be used in legal proceedings. However, ABTG requires prior notification if a particular test or service will be used in any legal proceedings / in a Court of Law.
    15. In the event that ABTG is required to provide an affidavit, or expert evidence in a Court of Law, an hourly rate plus expenses shall apply.
    16. It is the Purchaser’s responsibility to ensure that all local laws and regulations are complied with at their cost. Unless otherwise agreed in writing by ABTG. The tests and services may be suitable for utilisation out of the jurisdiction of Australia, but ABTG is unable to provide any warranty of any kind which may be imposed in countries other than Australia.
    17. Purchasers agree to apply for, provide Samples, supply all requested information, and use the test or service ordered as well as any results or reports, in a legal and ethical manner. ABTG shall not be liable for any such failure by the Purchaser or any other person.
    18. The Purchaser accepts that DNA profiles may be used anonymously for statistical purposes.

    4. The Purchaser accepts that due to the indirect nature of broader relationship testing (e.g. aunt to nephew testing), a conclusive result is not always possible. An inconclusive test result will not be grounds for a refund.
