At home covid antigen test kit instruction says to discontinue test if the nasal swab gets tainted with blood. why? does bloody samples tend to create more false positives or false negatives?

This is more a desire not to further injure your nasal membranes than any problem with the test. If the genetic material of the germ is present the test will identify it in most cases.
