ANA 12 Plus Profile (RDL)

CPT: 86038


  • ANA 12 Plus
  • ANA 12 Plus Panel

Test Includes

ANA 12 Plus Profile is reflexive and consists of the following: Anti‐Nuclear Ab (ANA). If positive, reflexes to following 14 components: Anti-Cardiolipin Ab (IgG, IgA & IgM Isotypes); Anti-Centromere Ab; Anti-Chromatin Ab; Anti-dsDNA Ab by Farr; Anti-La (SS-B) Ab; Anti-Ro (SS-A) Ab; Anti-Scl-70 Ab; Anti-Sm; Anti-TPO (Thyroid Microsomal Peroxidase) Ab; Anti-U1 RNP; C3 Complement; C4 Complement; Rheumatoid Factor by Turb; Anti-CCP (Cyclic Citrullinated Peptide) Ab.

If ANA is positive, all tests listed are performed. If ANA is negative, an Anti‐Ro (SS‐A) Ab test is performed to catch the small percentage of ANA false negative results. ANA includes titer & pattern.

ANA 12 Plus Profile, Do All is not reflexive and is a separate test code (use 520175).

Test Details


The ANA 12 Plus Profile is a reflexive assay. If the ANA titer is negative, no further tests are performed except for Anti-Ro Ab. Anti-Ro is performed to find the very small percentage of false negative ANAs. If the ANA titer is positive, the complete profile is performed. The ANA test detects autoantibodies that bind to the nuclear components of HEp-2 cells. A positive ANA titer is not specific, but indicates the presence of one or more autoantibodies. Profiles of specific autoantibodies have diagnostic and potential prognostic utility.
