What does a speckled ANA pattern mean?

Speckled: Fine and coarse speckles of ANA staining are seen throughout the nucleus. This pattern is more commonly associated with antibodies to extractable nuclear antigens. This pattern can be associated with Systemic Lupus Erythematosus, Sjögren’s syndrome, Systemic Sclerosis, Polymyositis, and Rheumatoid Arthritis.

Whats a positive ANA test mean?

In most cases, a positive ANA test indicates that your immune system has launched a misdirected attack on your own tissue — in other words, an autoimmune reaction. But some people have positive ANA tests even when they’re healthy.

Causes of a false-positive ANA include infection, malignancy, and certain medications. Therefore, a positive ANA test does not equal a diagnosis of lupus or any autoimmune or connective tissue disease.

What does a positive ANA HEp 2 mean?

The presence of antinuclear antibodies (ANA) indicates the possibility of autoimmunity and the indirect immunofluorescence (IIF) assay on HEp-2 cells is the standard blood test (ANA-HEp-2) used to detect ANA.

Does a speckled ANA indicate an autoimmune illness?

The speckled pattern is seen in many conditions and in people who do not have any autoimmune disease. These patterns are determined by technical experts who routinely interpret the tests.

Can you have a positive ANA and have nothing wrong?

The ANA test is very sensitive for the diagnosis of autoimmune diseases but results in many false positives. It has been reported that up to 15% of completely healthy individuals have a positive ANA test without an autoimmune disease and that ANAs are measurable in approximately 25% of the population.

Can stress cause high ANA levels?

Signs of stress-related ANA reactivity were seen among connective tissue disease (CTD) patients (including patients with systemic lupus erythematosus; mixed CTD; calcinosis, Reynaud’s phenomenon, esophageal motility disorders, sclerodactyly, and telangiectasia; scleroderma; and Sjögren’s syndrome): 11% showed stress- …
