Laboratory Diagnosis of Tick-Borne Infections

Patient Case 3 (continued)

July 2010

Now that we’ve reviewed some of the standard laboratory methods that are available for the diagnosis of Lyme disease, let’s return to our patient case for an update. A serum sample was submitted for Lyme serology, and the results of the screening enzyme immunoassay were positive. The physician receives the report of the screen EIA and questions “Is this diagnostic for Lyme disease?” To answer this question, I’d like for us to review the algorithm recommended by the Centers for Disease Control for Lyme serologic testing.
