A saliva-based test promoted as a non-invasive way to diagnose endometriosis is attracting attention, including in social media videos, but Australian experts say the evidence behind it is still not strong enough. The product, known as the Ziwig Endotest, analyzes microRNAs in saliva and looks for patterns that are said to be associated with endometriosis.
Its manufacturers say the test can diagnose the condition accurately, which helps explain its appeal. A saliva test sounds simpler and less invasive than many people expect from endometriosis assessment, making it an eye-catching option for patients searching for answers.
However, Australian experts are warning that there is not yet enough reliable research to show the test works consistently in real-world clinical use. Their concern is not just whether the technology can detect a signal in research settings, but whether it can deliver dependable results across the broader population that would use it.
The discussion around the Ziwig Endotest highlights a wider issue with emerging health tools: promising diagnostics can gain momentum online before the supporting evidence is fully established. Based on the concerns raised by Australian specialists, the key question is whether the endometriosis saliva test has enough real-world validation to support the claims being made for it.
