Interviewee: We also do not treat the preliminary Lyme test. There are two types of lab test, one is called a Lyme titer or an ELISA test and that test is not specific. Many kinds of very common infections that people have had in the past or bacteria that they have been exposed to in the past can make that test turn positive even though it is not the kind of infection for Lyme disease so if that is screening test is positive, then the doctor needs to go ahead and order the more specific Lyme test and only if that test is positive called the Western blot would we treat with antibiotics. Interviewer: You need a certain number of positives to say this? Interviewee: You do. There are certain criteria so when we do that test, that Western blot test, there are two things that we have learn. One is something called IgM and that is the body’s immune system’s reaction for an early infection, something new and for an IgM to be positive, there should be three of those bands, three of those proteins that show up as positive and for the IgG bands which show an infection that happened months ago, that one needs to have five bands that are positive in order to be a true positive test for Lyme disease.
