Useful For Suggests clinical disorders or settings where the test may be helpful

Evaluation of patients with signs and symptoms compatible with connective tissue diseases

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Test IDReporting NameAvailable SeparatelyAlways Performed
ANA2Antinuclear Ab, SYesYes
CCPCyclic Citrullinated Peptide Ab, SYesYes

Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

Test IDReporting NameAvailable SeparatelyAlways Performed
CMACentromere Ab, IgG, SYesNo
RIBRibosome P Ab, IgG, SYesNo
ENAEAb to Extractable Nuclear Ag Eval,SYesNo
ADNARdsDNA Ab with Reflex, IgG, SYesNo

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

If antinuclear antibodies are > or =3.0 U, then antibodies to double-stranded DNA (dsDNA), extractable nuclear antigen evaluation, ribosome P, and centromere are performed at an additional charge.


If result from dsDNA test is borderline, then dsDNA antibody by Crithidia IFA will be performed at an additional charge.
