Health Minister Greg Hunt has denied accusations he interfered in a regulator's decision on whether to review a self-testing flu kit made by a Liberal donor's company.

Emails obtained under freedom of information show Mr Hunt's office was "very keen" for the Therapeutic Goods Administration (TGA) to review the use of self-diagnosing devices, including for the flu.

Health Minister Greg Hunt poses with Jim Darrouzet and an Ellume self-testing kit in September 2017.

It followed an enquiry about Ellume, and its flu-test device, to Mr Hunt's office. Ellume's chair is multi-millionaire entrepreneur Paul Darrouzet, who donated $100,000 to the federal Liberal party in 2017 and has also donated to the Queensland Liberal National Party.

In May last year, John Skerritt, the deputy secretary at the TGA, emailed colleagues: "Had another call from the MO (minister's office) - they are very keen for this issue to be reviewed."
