RT Journal Article SR Electronic T1 Appropriate laboratory testing in Lyme disease JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 751 OP 759 DO 10.3949/ccjm.86a.19029 VO 86 IS 11 A1 Teny M. John A1 Alan J. Taege YR 2019 UL http://www.ccjm.org/content/86/11/751.abstract AB Testing for Lyme disease is challenging and if done incorrectly can lead to unnecessary treatment. To interpret serologic test results, first assess the patient’s pretest probability of infection based on the probability of exposure and clinical findings. Two-tiered testing remains the gold standard in diagnosing Lyme disease, although new guidelines may be published soon.
