In my lyme disease panel the Elisa was positive, the western blot was negative. My doctor said Elisa false positives are common. Is this true and why?

In brief: Yes

The Western blot is a more direct measurement than Elisa.

There are false positives because the panel checks for antibodies that are present in people who do not have Lyme disease as well as in people who do have Lyme disease. People can make some of those antibodies without having the Lyme bacteria.
