Leaky Gut Test

A healthy gut is important for overall wellbeing. We have developed an industry leading test for leaky gut which is easy and fast, with results available within 48 hours.


One in two people are affected by poor gut health. Increased Intestinal Permeability, also known as 'Leaky Gut' occurs when the cells lining the gut become damaged, allowing toxins, bacteria, and undigested food particles to leak out of the gut and into the body. This can lead to gut pain, diarrhoea, and bloating, as well as affecting concentration, mood, and the immune system.

The unique CSIRO test can diagnose leaky gut using a blood sample. The test is suitable for, and available to, everyone.

How to get the test

The CSIRO Nutrition and Health Research Clinic in South Australia is the only facility offering this unique test.

  • Take the referral form to your GP and discuss your options. Your GP is able to complete the referral form for your test. You may wish to take a copy of the information sheet with you. 
  • Call the CSIRO clinic to make an appointment. Bring your referral form with you to the appointment. Payment is required on the day of the test.  
  • Do not consume any food or drink (water only) for 10 hours before your appointment. Allow about two hours for the test. Much of this time will be waiting for the right time to take a blood sample after consuming a small drink. You might like to bring some quiet entertainment to your appointment.
  • The results will be sent to your referring health professional. Discuss your results and ongoing management with your doctor or a dietitian.
