ANA titer and pattern on HEp-2 only

Test Number002
MethodIFA
Reference Range

Negative: < 1:40 titer
Positive: ≥ 1:40 titer

CPT Code86038
Schedule Turnaround TimeAssay performed daily Mon.-Fri. Report availability is within 48 hours from the time of specimen receipt.
Specimen RequirementsSpecimen need not be refrigerated or frozen. Collect 5-10 ml of blood in a red top or serum separator tube. If possible, separate serum from clot and place into orange tube provided with IMMCO collection kits. Do not puncture top of orange tube. If separation facilities are not available, the blood can be sent in the tube used for collection.
Sample StabilitySample is stable at ambient temperature during shipment. If sample is stored prior to shipment, it is stable refrigerated (2-8°C) up to five days and frozen (-20°C or lower) up to one year.
Clinical RelevanceFor detection of antibodies to nuclear antigens. The homogeneous pattern is primarily associated with systemic lupus erythematosus (SLE). Antibodies to centromere antigens are highly specific for CREST syndrome, a limited form of systemic sclerosis. Centromere antibodies can also occasionally befound in low titers in some other autoimmune variants. Anti-nuclear antibodies with a speckled pattern are commonly associated with systemic lupus erythematosus (SLE), although they do occur in some cases of Sjögren’s syndrome and mixed connective tissue disorders. ANA antibodies with a nucleolar pattern are commonly associated with systemic sclerosis (SS), although they do occur in some cases of systemic lupus erythematosus (SLE) and overlap syndromes. Overlap syndromes include polymyositis/dermatomyosistis.
