"Your health care provider has ordered a laboratory test for the presence of Lyme disease for you. Current laboratory testing for Lyme disease can be problematic and standard laboratory tests often result in false negative and false positive results and, if done too early, you may not have produced enough antibodies to be considered positive because your immune response requires time to develop antibodies. If you are tested for Lyme disease and the results are negative, this does not necessarily mean you do not have Lyme disease. If you continue to experience unexplained symptoms, you should contact your health care provider and inquire about the appropriateness of retesting or initial or additional treatment.".
