Testing

  • According to the International Lyme and Associated Diseases Society (ILADS) guidelines, currently the blood tests widely used, ELISA and Western Blot, are not always reliable to make a definitive diagnosis of Lyme disease.
  • The accuracy of testing to support the Lyme diagnosis depends on a number of variables including the specificity and sensitivity of the tests and the types of tests used.
  • Most tests currently available are indirect detection tests (the immune system’s response to the disease), and look for antibodies to Lyme disease spirochetes, not the bacteria.
  • The diagnosis should be a clinical one based upon signs and symptoms, tick exposure and evaluation of test results.
  • Currently, no tests can rule out Lyme disease.  A person can test negative, but still have Lyme disease.

Treatment

  • Treatment protocols can vary due to duration of undetected infection, presence of co-infections, individual’s immune system response and genetic predisposition.
  • Oral, intravenous and intramuscular medications may be used in the treatment of Lyme and other tick-borne diseases.
  • Prophylactic (preventive) treatment should be considered when bitten by a tick in a Lyme endemic area because left untreated the bacteria can cause severe, multi-system manifestations including cardiac, arthritic and neurologic abnormalities as well as meningitis.
  • It is important to note that:
    • Up to 40% of ticks tested in some areas of Connecticut are positive for Lyme disease (CT Agricultural Experiment Station—Tick Management Handbook, published 2004).
    • Because the nymph tick is difficult to detect due to its tiny size, most Lyme disease cases are associated with the bite of a nymphal stage of the blacklegged tick, of which 10-36% may be infected with Lyme disease spirochetes.  Adult ticks are larger and thus easier to find, but do have a higher infection rate, up to 60% in Lyme endemic areas (CT Agricultural Experiment Station—Tick Management Handbook, published 2004).
