DNA testing is widely regarded as the gold standard for determining biological relationships. However, there are two critical concepts often misunderstood when discussing DNA testing for parentage: accuracy of the test and probability of paternity. While both are essential, they serve different purposes and are calculated in entirely different ways.

Twins are often categorised as either identical or fraternal, based on their genetic makeup. However, there's a rare phenomenon known as heteropaternal superfecundation that adds an unexpected twist to the concept of fraternal twin - they can actually have different fathers. Yes, you read that right. Have we seen this at Identilab? Yes, not once, but twice!

The words “sex” and “gender” are often used interchangeably, including on medical forms and identity documents. The difference between sex and gender has particular implications for DNA testing, especially for individuals who are intersex, transgender, non-binary or gender non-conforming.

We sometimes get asked why our tests aren't $89 like other companies on the internet. These companies are usually located overseas, meaning it can take longer to get your results, it's hard to talk to someone if you need your results explained to you, and you are not protected by Australian Privacy Laws.

The process of having a DNA test performed at Identilab - from ordering a test to getting your results - involves multiple steps and depends on a variety of factors.

Are you questioning whether your child is yours but you're not sure where to start or what the process of paternity testing involves? In this article we'll outline the options available to you when undertaking a paternal DNA test at Identilab, and the steps involved.

If you have received an order from the Family Court to undergo paternity testing, or you need to prove paternity for other legal reasons, such as adding your name to a child's birth certificate, you will need a legally admissible DNA test from a NATA accredited laboratory.

Knowing if your twins are identical or not is important for medical, social, financial, and ethical reasons. Scans performed during pregnancy are not a reliable way of determining zygosity.

Due to the science behind DNA testing, your results must be worded in a certain way that can be confusing. Read on for some further information to help you understand it better.
