But some experts have urged caution over the test, with one saying that antibody tests for Covid-19 are "good for satisfying people's curiosity but no more".
This comes amid growing public interest on how the Roche antibody tests, when they are finally made available to the public, will contribute to the Government strategy on easing the ongoing lockdown.
"Yvonne Fovargue MP said: "£70 with postage for a test which is not completely accurate seems excessive.
The blood tests were expected to be available to large labs by late May, the company said, adding that it would be able to provide more than 25 million tests per month from June thanks to an upgrade to its manufacturing site in MA.
The tests will be based on blood samples from patients, which will be analyzed for antibodies to show if someone has had the virus.
Superdrug doctor ambassador, Dr Zoe Williams comments "Now that Public Health England have approved certain antibody tests, it is great that Superdrug are offering the validated test to its customers".
Health Secretary Matt Hancock will set out further details later about a deal on the supply of the tests after negotiations were carried out.
Superdrug has become the first high street retailer to launch a coronavirus antibody testing kit and you can purchase one for £69 ($85).
In April, Alex Templeton, CEO of test supplier to businesses, Qured, told Personnel Today: "We offer tests in which the samples are collected by the patients themselves at home or at the workplace, and are couriered to our lab partner for rapid analysis".
Another antibody test being pioneered by Oxford University could be available by the end of May, according to Professor John Newton, the UK's national testing co-ordinator.

People that are showing symptoms of the virus should not take the test for at least two weeks for it to be accurate, Superdrug said.
Professor Adam Finn, of the University of Bristol said, "Until we know how strong and long-lasting immunity is after infection, it is hard to know what to do about the results of these tests, even if the tests are reliable". Superdrug have maintained that those who test positive, i.e. have antibodies, should still adhere to the Government's social distancing guidelines.
"We're launching a Covid-19 antibody test because we're confident of its accuracy and reliability", explains Superdrug's healthcare director Michael Henry.
Around 6 per cent of staff were found to have had the virus but, crucially, under-40s who had tested positive came back negative, suggesting the test may not be useful for the wider population.
There is a variation in the accuracy of tests.
But he added: "Whilst this may be an indication of functional immunity, confirmation of this is awaited from large scale studies presently under way". An antigen is a structure within a virus that triggers the immune system's response to fight off the infection.
The World Health Organization says there is no evidence people who have recovered from Covid-19 and have antibodies are protected from being infected again.
"We need much more information and data on immunity before we can understand the importance of having antibodies to the virus".
