   How accurate are Lyme disease tests?

   • Tests are less accurate for a short period of time after you first become infected. That’s because Lyme disease tests look for proteins created by your immune system to help you fight off infection (antibodies), rather than for the infection itself, and it can take a few weeks for your body to make enough antibodies to cause a positive test.

   What percentage of Lyme disease tests are false positive?

   • In the United States it was recently estimated that less than 12% of Lyme disease tests were for true infections [ 75 ]. The LD test results for patients who do not meet the clinical criteria can be used to rule out LD, but a positive test is likely to be a false positive.

   How long does it take to get Lyme disease test results?

   • It takes a few days to get results. If the first test comes back positive or unclear, the lab will do the second blood test. If the first test comes back negative, the CDC does not recommend the second test. However, according to the CDC the second test must be positive for you to be diagnosed with Lyme disease.

   • The First Test: Elisa
   • The Second Test: Western Blot Or A Second Elisa
   • A Possible Drawback of The Two-Step Testing System

   This blood test is for antibodies against the Lyme disease bacteria. Because it can take some time for your body to produce antibodies, this test isn’t always accurate soon after a person is infected.

   There are two options for the second test. One is called a Western blot, which looks at how your antibodies react to specific parts of the Lyme disease bacteria. The Western blot test has been part of the two-step testing system since 1994 and is more commonly used. The other option is to do a second ELISA test, which measures antibodies to a speci...

   The CDC testing guidelines recommend a second test only if the first test is positive or unclear. Because the first test may not pick up antibodies soon after possible exposure to the Lyme disease bacteria, that means a person with Lyme disease may never get the second test. So, if your ELISA test is negative, you may want to ask your doctor to rep...

Here’s a quick breakdown: Early stage : Within a month of exposure to Lyme disease, during its “localized” phase, testing isn’t generally necessary if Lyme-specific symptoms ...
