Jersey's government is urging people to exercise "extreme caution" before making use of a new drive-through coronavirus testing centre.
Orchid Care Services is opening its facility on the former Tamba Park tourist attraction site, in St Mary, on Friday and promises people results of their finger-prick blood test within half an hour.
Those behind the business say their tests are 96% accurate, and are offering them for £74.95, with discounts for children and critical workers.
But the government says it is urgently investigating those claims.
Orchid Care Services is offering to share its results data with the government.
A government spokesperson has told ITV News it would be "unlikely" to use any data from a company whose processes it has not reviewed.
James Ahier, Managing Director of Orchid Care Services told ITV that since having had the first case of Covid-19 confirmed in their own organisation back in March, testing was something they had spent a lot of time looking into.
Mr Ahier also said the timing was coincidental, and that they were planning to offer a private testing facility whether or not the government had put island wide testing on hold.
