ANA Screen, IFA, Reflex Titer/Pattern, and Reflex to Multiplex 11 Ab Cascade

Supply #193262 Red/Gray SST 8.5mL

Test Code: 16814

CPT Code(s): 86038

Methodology: Immunofluorescent Assay (IFA)

Clinical Significance: Antinuclear antibodies are associated with rheumatic diseases including Systemic Lupus Erythematous (SLE), mixed connective tissue disease, Sjogren's syndrome, scleroderma, polymyositis, CREST syndrome, and neurologic SLE.

Includes: The ANA Screen, IFA, Reflex Titer/Pattern, and Reflex to Multiplex 11 Ab Cascade begins with an ANA Screen, IFA.

If ANA Screen, IFA is positive, then ANA Titer and Pattern will be performed at an additional charge (CPT code(s): 86039).

Additionally, five antibodies will be performed at an additional charge: dsDNA (CPT code(s): 86225), Sm/RNP (CPT code(s): 86235), RNP (CPT code(s): 86235), Sm (CPT code(s): 86235), and Chromatin (CPT code(s): 86235).

If any of those five antibodies are positive, the cascade stops and the results are reported.

If all five of those antibodies are negative, four additional antibodies will be performed at an additional charge: SSA (CPT code(s): 86235), SSB (CPT code(s): 86235), Scl-70 (CPT code(s): 86235), Jo-1 (CPT code(s): 86235).

If any of those four antibodies are positive, the cascade stops and the results are reported.

If all four of those antibodies are negative, the following two additional antibodies will be performed at an additional charge: Ribosomal P (CPT code(s): 83516) and Centromere B (CPT code(s): 86235).

Please note the cascade stops upon the first positive antibody result(s) found in a group and an interpretive message is applied based on this information. It is possible that antibodies in subsequent groups are also positive, but will not be added, billed, or reported. Please contact your local Quest Diagnostics Laboratory if you are interested in adding this additional testing.
