This test looks for antinuclear autoantibodies (ANAs) in your blood to help detect an autoimmune disease and provide information to help you and your healthcare provider to determine next steps. If ANAs are present, additional testing will be done on the sample you have already provided to identify what type of autoimmune disease you may be suffering from.
No doctor’s visit needed.
This test includes the following process:
An ANA Screen Immunofluorescence Assay (IFA) is done first to look for antinuclear autoantibodies in human cells.
If the ANA Screen IFA is positive, testing will occur to look for dsDNA, Sm/RNP, RNP, Sm, and Chromatin antibodies. If any of those five antibodies are positive, the cascade stops, and the results are reported.
If all five of those antibodies are negative, testing will continue and look for SSA, SSB, Scl-70, and Jo-1 antibodies. If any of those four antibodies are positive, the cascade stops, and the results are reported.
If all four of those antibodies are negative, testing will continue and look for Ribosomal P and Centromere B.
Please note, after the initial ANA Screen by IFA, testing will stop when the first positive antibody result(s) in a group are found. It is possible that antibodies in subsequent groups are also positive, but will not be tested, or reported.
No special preparation is required.
