A negative result on an ANA test means that antinuclear antibodies were not found in your blood, and you’re less likely to have an autoimmune disorder. But a negative ANA test doesn’t completely rule out the possibility that you could have an autoimmune disorder.
What autoimmune disease has a negative ANA?
A negative test A negative ANA test effectively excludes a diagnosis of ANA associated rheumatic disease such as drug-induced lupus and, in the majority of cases, SLE, systemic sclerosis/scleroderma and mixed connective tissue disease, particularly where there is a low pre-test probability of these conditions.
What blood tests indicate lupus?
Antibody blood tests The test you will hear about most is called the antinuclear antibodies test (the ANA test). 97% of people with lupus will test positive for ANA. ANA connect or bind to the nucleus or command center of the cell. This process damages and can destroy the cells.
What are the 4 criteria for lupus?
Butterfly (malar) rash on cheeks. Rash on face, arms, neck, torso (discoid rash) Skin rashes that result from exposure to sunlight or ultraviolet light (photosensitivity) Mouth or nasal sores (ulcers), usually painless. Joint swelling, stiffness, pain involving two or more joints (arthritis)

What are the symptoms of borderline lupus?
The most common symptoms of lupus are joint pain, skin rash (which can include unusual reaction to the sun), severe fatigue, chest pain with deep breathing (called pleurisy pain).
Can lupus go undetected in blood tests?
Diagnostic Criteria. Systemic lupus erythematosus can be difficult to diagnose: no single blood or imaging test can definitively identify it, and its symptoms can be vague, progress slowly, change, or mimic other conditions, such as rheumatoid arthritis. As a result, it’s important to consult a rheumatologist.
What level of ANA indicates lupus?
The initial requirement of the criteria for lupus diagnosis is a positive ANA test with a titer of at least 80. The numerical value of the titer refers to the ratio of blood serum being evaluated to a dilution agent.
What diseases mimic lupus?
