Auto Immunity – ANA Profile

It tests your blood for 17 autoantibodies reported on an extended ANA profile: proteins your immune system has made against your own tissue, most against parts of the cell nucleus and a few against other cell structures. Instead of a single yes or no, the report names which are present, and that pattern points your doctor towards one condition rather than another.

No. A positive antibody supports a diagnosis but never confirms one by itself. Lupus is identified clinically, from symptoms, examination and several tests read together. Some antibodies, such as anti-Sm and anti-dsDNA, weigh heavily in that assessment; others turn up in people who never develop a disease.

Yes, and it is common. Low-level antinuclear antibodies appear in people with no autoimmune disease at all, more often as we get older, and they can follow an infection or accompany certain medicines. That is precisely why the result has to be read next to your symptoms.

It makes an antibody-associated connective-tissue disease less likely, but it does not exclude autoimmune illness: some conditions are antibody-negative, and antibodies can appear later in the course. If your symptoms persist, your doctor may test other things or repeat this panel in time.

Broadly: dsDNA, nucleosome, histone, Sm, PCNA and Rib-P0 towards systemic lupus erythematosus; SS-A/Ro and SS-B/La towards Sjögren's syndrome; CENP-B and Scl-70 towards systemic sclerosis; U1-snRNP towards mixed connective-tissue disease; Jo-1, Mi-2, PM-Scl and Ku towards inflammatory muscle disease; and AMA-M2 towards primary biliary cholangitis.

Joint pain that moves from one joint to another, prolonged fatigue, recurrent unexplained fevers, muscle aches and weakness, a rash that worsens in sunlight, or persistently dry eyes and mouth. Symptoms lasting weeks with no obvious explanation are the usual reason to test.

A single result tells you antibodies are present; it does not say which. Naming the target changes what your doctor does next, because anti-Scl-70 leads somewhere different from anti-SS-A or anti-Jo-1. That specificity is the whole point of reporting each target separately.

Usually not. Once an antibody pattern is known it rarely changes in a way that alters treatment, so repeating the whole panel adds little. The exception is anti-dsDNA, which doctors do follow over time in lupus. Your rheumatologist will say whether a repeat is worthwhile.

No fasting and no special preparation, so any appointment time works. Do not stop prescribed medicines in order to take the test; tell your doctor what you take instead, because a small number of drugs are associated with an antibody pattern of their own.

The panel is AED 459, including free home sample collection anywhere in Dubai seven days a week and a physician-reviewed Smart Report. Results take 7 to 8 days because each antibody is tested individually rather than on a routine analyser. Our care team can advise via contact.
