At-Home vs Legal DNA Testing: What’s the Difference & Which One Do You Need?

Both at-home and legal DNA tests use the same science, but the way samples are collected makes all the difference. Here’s how to choose the right option for your situation - from personal peace of mind to court-admissible results.

Your DNA, Your Privacy: How Identilab Handles Genetic Data 

In recent years, public concern around genetic privacy has grown, with stories of data misuse, major breaches, and even the bankruptcy of companies like 23andMe. At Identilab, we’re not in the business of data mining or selling your DNA; your sample is used only for the purpose you’ve engaged us for, and never added to a database or shared with third parties.

Understanding Zygosity: Identilab’s Collaboration with Twins Research Australia

Ever wondered what makes twins truly identical - or not? In this blog, we explore zygosity testing, why it matters, and our collaboration with Twins Research Australia to make testing easy and accessible for families across the country.

Understanding Y-STR Testing in Kinship Analysis: When It Works, and When It Doesn’t

Y-STR testing can be really helpful when you’re trying to figure out male-line relationships - especially if the direct father can’t be tested. In this post, we break down how it works, what it can (and can’t) tell you.

The Unexpected Impact of DNA Ancestry Tests

Direct-to-Consumer (DTC) DNA ancestry tests have surged in popularity, promising fascinating glimpses into our heritage and the chance to connect with distant relatives. But for some, these tests do more than satisfy curiosity - they uncover unexpected truths.

Understanding the Difference Between Accuracy and Probability of Paternity

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.

Heteropaternal Superfecundation – aka Twins with Two Dads

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!

Sex, Gender, and DNA Testing

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.

How much does a DNA test cost in Australia 2025?

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.
