ANA Blood Test: Order, Results & What They Mean

Testing.com's ANA reference article explains IIF as the standard method, that a positive screen triggers automatic reflex testing for titer and pattern on the same sample, and how titer thresholds and staining patterns guide interpretation and follow-up specific-antibody testing. Candidate notes: Standard method: IIF/IFA on HEp-2 slides; ELISA/multiplex alternatives may differ in sensitivity and pattern reporting Titer guidance: 1:40/1:80 often low/clinically insignificant in asymptomatic people; >=1:160 more likely meaningful with symptoms Pattern associations: homogeneous->lupus, speckled->several connective tissue diseases, nucleolar->scleroderma, centromere->CREST Limits noted in the record: Reference ranges vary by lab; the page notes its own range flags >1:80 as elevated Primarily patient-facing; citations lean on ACR and MedlinePlus statements rather than primary lab protocols A positive ANA is not a diagnosis. Claims in this record are not verified.
