Not good. If you've had it for a long time it won't show up in your blood.
"The laboratory tests used for Lyme Disease diagnosis include: detection of
Borrelia surface antigens by enzyme-linked immunosorgant assay (ELISA),
immunofluorescent assay (IFA), and Western blot of Borrelia proteins.
Alternatively, polymerase chain reaction (PCR) for Borrelia DNA has been
used to detect the intact organism in blood. A true-positive test result
usually consists of more than one positive test from the above list. The
problem with these tests are that they are blood tests requiring the
presence of antibodies or Borrelia proteins in the blood or are dependent on
the spirochete and thus its DNA being present in the blood. Some of the
tests, such as serology testing for antibodies against Borrelia antigens,
can cross-react with other microorganisms and in some cases are only useful
4-6 weeks after onset of signs and symptoms; thus the quality of the test
can vary. The most sensitive type of test (PCR) requires that the spirochete
be released into the blood where its DNA can be detected. "
