Ordering Guidance

This test can be used in a complementary fashion with a quantitative enzyme-linked immunosorbent assay to confirm a positive result, especially if it is a low-level titer. Since the immunofluorescence is more sensitive, it can also be used to detect or follow patients with low level antibodies not detected by ELISA.
