I meant to say sensitivity of ANA in autoimmune diseases and non rheumatic diseases. :)
I'm in dozens of forums. You can ask questions in different forums as someone may have the answer on another forum.
In most cases, a positive ANA test indicates that your immune system has launched a attack on your own tissues. Eek! But a positive ANA is not diagnostic of any condition as such. A more through work up is needed and of course symptoms help with what other labs to look for. Also, check vitamin D deficiency levels as well as most autoimmune diseases will show up with concurrent vitamin D deficiency.
My symptoms of weight gain, swelling, fatigue, constipation and poor appetite (also felt full very quickly after eating due to gastroparesis) are some of my symptoms of Hashimoto's thyroiditis (the most common cause of hypothyroidism).
Sensitivity of ANA in non rheumatic disease:
Systemic lupus erythematosus (SLE): 95–100%
Scleroderma: 60–80%
Mixed connective tissue disease: 100%
Polymyositis/dermatomyositis: 61%
Rheumatoid arthritis: 52%
Rheumatoid vasculitis: 30–50%
Sjögren's syndrome: 40–70%
Drug-induced lupus: 100%
Discoid lupus: 15%
Pauciarticular juvenile chronic arthritis: 71%
Hashimoto's thyroiditis: 46%
Graves' disease: 50%
Autoimmune hepatitis: 100%
Primary autoimmune cholangitis: 100%
Primary pulmonary hypertension: 40%
