Hello decadence
Because a positive test is far move accurate.....about 96%. So if it says you've got it, you've got it (known as sensitivity). The specificity is the ability of the test to correctly identify those without the disease (true negative rate) and it is this which is the problem. So my friend tested negative but actually had the virus.If a negative test does not mean negative, why have various posters been bleating on about testing for weeks? If negative does not mean negative, the test is a pointless waste of money, time, and resources. IMHO.
The symptoms are similar to things other than CV.
