Accuracy and immunity: the ethics of Covid-19 home testing
Developing a Covid-19 test which can be deployed en-masse among the general population could be an essential step towards flattening the curve and limiting the impact of the pandemic. But even once an effective testing solution can be discovered and deployed, this comes with its own set of ethical issues. Chloe Kent reports.
longside the myriad difficulties involved with developing the right kind of Covid-19 test to use at home, concerns have been raised about the overarching impact of a test once it has been made.
The US Food and Drug Administration (FDA) has significantly relaxed its regulatory pathways to expedite the production and distribution of Covid-19 tests. State Departments of Health are now able to approve tests without direct engagement from the FDA. Manufacturers are also able to distribute tests across state lines for 15 days between their own validation and the granting of an emergency use authorisation and antibody tests are widely permitted.
Steps like these are essential during a global pandemic, but some consumers are still concerned about the reliability of the tests they can access. If a home test is deployed at a large scale and its accuracy turns out to be subpar, the consequences could be catastrophic.
The UK Government, for example, has now admitted that none of the 17.5 million antibody tests it ordered work well enough to be used.
Even without an NHS option, Warwick Medical School honorary clinical lecturer Dr James Gill cautions UK residents against opting for the private home-use tests hitting the market instead, saying, “I’m intrinsically resistant to something that the patient has to pay for when the NHS offers a service. Yes, they may pay for something to get it faster, but if that particular service or brand is not being offered by the NHS why is that?”
An immunity armband?
Much discussion has also surrounded the concept of ‘immunity passports’, some sort of document or badge a recovered Covid-19 patient with a positive antibody test could keep on their person to prove that they’re immune to the disease and safe to be outside.
“If something like that were to be implemented, I would hope it would only be for a short period of time. It’s easy to see how that could be abused,” says Gill. “There are stories of NHS workers being attacked and having their passes stolen so people can get access to things. How would be that any different to an ‘I’m Covid-free’ armband?”
