CPT Code(s)

86038

Preferred Specimen(s)

Minimum Volume

0.2 mL

Alternative Specimen(s)

Collection Instructions

Overnight fasting is preferred.

 

The ANA IFA with Reflex to Titer/Pattern/Cascade begins with an ANA (Anti-Nuclear Antibody) IFA Screen.

 

If the ANA, IFA screen is positive, then the ANA, Titer & Pattern will be performed at an additional charge (CPT code: 86039).

 

Additionally, five antibodies will be performed at an additional charge:

dsDNA (CPT: 86225)

Sm/RNP (CPT: 86235)

RNP (CPT: 86235)

Sm (CPT: 86235)

Chromatin (CPT: 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: 86235)

SSB (CPT: 86235)

Scl-70 (CPT: 86235)

Jo-1 (CPT: 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: 83516)

Centromere B (CPT: 86038)

 

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.
