In this situation, treatment with a drug that covers both diseases (eg, cefuroxime or amoxicillin-clavulanate) is an effective strategy. Approximately 25% of patients with Lyme disease are children, which is the same percentage of patients who do not recall a tick bite. The Western blot test looks at whether you have an immune response the production of IgM or IgG antibodies to specific proteins (antigens) on the Lyme disease bacteria. [QxMD MEDLINE Link].
