## Indications for use
The iDart™ Lyme IgM ImmunoBlot Kit is an immunoblot assay intended for the in vitro qualitative detection of IgM antibodies to Borrelia burgdorferi in human serum. The iDart Lyme IgM ImmunoBlot Kit is intended to detect antibodies to Lyme Screen Antigen (LSA) and multiple other B. burgdorferi antigens following a modified two-tier test methodology. Positive results from the iDart Lyme IgM ImmunoBlot Kit are supportive evidence for the presence of antibodies and exposure to B. burgdorferi. Negative results do not preclude infection with B. burgdorferi. iDart™ Lyme IgM ImmunoBlot Kit is intended to aid in the diagnosis of Lyme disease and the test kit should only be used on samples from patients with clinical history, signs and symptoms consistent with Lyme disease. The iDart Lyme IgM Immunoblot Kit is not intended as a screen for asymptomatic patients. Test results are to be used in conjunction with information obtained from the patient’s clinical evaluation and other diagnostic procedures.
