Hi opugirl, just want to make sure our terminologies are the same so we can describe things the same. Still learning here but from my understanding when referring to Lyme specificity:
Specificity is how accurate a test is. For instance, if a test is 99 percent specific then it is 99 percent accurate in the sense that it produces false negatives 1 percent of the time for people with Lyme. Specificity doesn't take into account the chances of a false negative it only addresses how accurate a positive result is.
For example, if someone tests positive for a highly specific test, there's almost no refuting that result. It is a
highly accurate test.
However, if someone with Lyme tests negative for a highly specific test, it doesn't mean the test isn't accurate, it just means the test has low sensitivity.
Does this sound right?
