Professor Sharon Peacock, director of the UKs National Infection Service told a House of Commons committee this morning that they would be made available either through Amazon or at High Street pharmacies like Boots.
At a daily press briefing on the coronavirus crisis on Wednesday, Prime Minister Boris Johnson and his specialist medical advisers confirmed the government was working on increasing the rate of testing, prioritising health workers.
"But we do need to ensure we understand how they operate, because these are brand new tests".
Asked if she meant the tests would be ready for roll-out within days rather than weeks, she said: "Absolutely".
The home test kits take just 15 minutes to use.
"You prick your finger like a diabetic would, then get a drop of blood and put it on a filter paper and then run some liquid to make that run into the test zone".
Professor Sharon Peacock, director of the National Infection Service at Public Health England, told the United Kingdom parliament on Wednesday that the group had developed finger-prick tests which establish whether a person has ever been infected with the virus.
The antibody test will aim to establish whether somebody has recovered from COVID-19, rather than whether they now have it.
Coronavirus home testing kits could be available to buy from shops like Amazon or Boots within a matter of days. "We have to be clear they work as they are claimed to do", she told lawmakers.
The news comes as the United Kingdom has entered lockdown in an attempt to stop the further spread of the novel coronavirus, and will hopefully allow people - including NHS doctors and nurses - to make quicker and more accurate decisions about the patients they are seeing who have symptoms.
Crucially, failing to test NHS staff also wastes valuable resources if they are forced to isolate unnecessarily, and can no longer treat COVID-19 patients.
Peacock said that the tests were now being evaluated to confirm whether they worked, which she said would happen by the end of the week, after which "several million" would be rolled out across the country. They could help society return to normal because people who have had the illness will be able to return to work or go out.
