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...

Since it takes a couple of weeks for the body to develop antibodies, tests like ELISA are less likely to be accurate in this phase.
