Every day, that you wait to get tested, you are more likely to have a false negative. I had very mild symptoms, like random metallic smells/tastes and some digestion issues, weeks before I got tested.
I tested negative 2x and every single doctor said that I definitely have covid. I’m under the CDC’s “presumed positive,” so I’m included in the numbers.
USA already has insanely high covid numbers. With all these false negatives, lack of testing kits, lack of insurance, imagine how many people really have covid?!
Here’s a news article about about why there are so many false negatives:
