NK Cell trial

The NK Cell trial: why it exists

I’m thrilled that after more than 20 years of research, the NK blood test I created and developed is finally undergoing a rigorous, prospective scientific trial. Research takes time, especially for pioneering new technology.

So far, I’ve shown that the NK activity blood test can discriminate between women with different levels of immune activity, and that this is associated with reproductive outcomes.

The research behind the test

I’ve linked this test to a new immune therapy I call the Bondi Protocol. A large retrospective study has shown it may be highly effective in women with high NK cell activity.

Why a formal trial matters

It’s always important to strive to prove things properly. To test our ideas rigorously, and to give more patients and doctors access to, and confidence in, what we’ve seen so far.

How the trial works

As part of my work with Genea, and in close collaboration with the Genea research team, we’ve set up a formal trial of the NK test. It’s accessible nationally at Genea, and it allows women to access the test for free.

As part of the trial design, the first embryo transfer is done without the result being known, so the data can be gathered properly and stand up to scrutiny.

If you want to discuss the trial

Patients who’d like to understand more about the trial are welcome to raise it at a consultation with me. I also know many patients don’t have the time, or the inclination, to wait on trial results. Direct access to the NK test, outside the trial, remains available, as it has for the last 15 years.

Frequently Asked Questions

It’s a national, prospective clinical trial testing the NK activity blood test developed by Dr Gavin Sacks, in a formal, rigorous way. It builds on more than 20 years of research and a large retrospective study.

Dr Sacks has shown that the NK activity blood test can discriminate between women with different levels of immune activity, and that this is associated with reproductive outcomes. A formal trial exists to test that relationship more rigorously than earlier research allowed.

As part of the trial, the first embryo transfer is done without the result being known, so the data can be collected reliably. Outside the trial, direct access to the NK test has been available for the last 15 years for patients who prefer not to wait on the trial process.

Yes. The trial makes the test accessible at no cost nationally at Genea.

Yes. Direct access to the test remains available, as it has for the past 15 years, for patients who don’t wish to wait for the trial process.
