Billionaire Elon Musk, grabbed headlines when he talked about the ‘inaccuracy’ of COVID testing after receiving 2 positives and 2 negatives on the same day.
There also have been endless reports of people being wrongly diagnosed with the infection, even while relying on the ‘gold standard’ tests. More recently, an erroneous fault at a UK-based testing lab led to over a 1000 people receiving wrong results on a single day. Loopholes like these have also led many to bat an eye over COVID testing standards, and wonder, how many genuine COVID-19 cases might be really there.
But, the question remains- how can a person get a fake positive result, even when they aren’t really infected?
