29-year-old male presents to the office with the complaint of bilateral knee pain...

The initial test is found to be positive. The test to confirm the diagnosis is?

Western Blot

Western blot is the confirmatory test for determining whether a person has Lyme disease.

It provides more information than enzyme linked immunosorbent assay (ELISA) regarding the type of antigens that are reacting, and has a high specificity.

This test is utilized when the ELISA test is either positive (due to chance of false positive results) or if the test is equivocal.

*If the ELISA test is negative, then a person is considered negative and would not require further testing.
