Can you have a negative ANA and still have an autoimmune disease?

A negative ANA test means that no antinuclear antibodies were detected; however, it is still possible for someone with a negative test result to have an autoimmune disease. If the patient's symptoms continue to linger, they may require additional autoimmune testing.

Can you have autoimmune disease without positive ANA?

A negative test for ANA may assist health care providers by decreasing the likelihood that a patient's symptoms are caused by an autoimmune disease. Some individuals, even those without a relative with autoimmune disease, may have a positive test for ANA and yet never develop any autoimmune disease.

Does ANA test for all autoimmune diseases?

A positive test doesn't mean that you have an autoimmune condition. Between 3% and 15% of people with no conditions have antinuclear antibodies. Some medicines or other diseases also can cause them. Not everyone who has an autoimmune disease will test positive.

What if my ANA test is negative?

A negative test means that certain autoimmune diseases are less likely to be present. Other tests may still be needed based on your symptoms. Some people with autoimmune diseases may get a negative test result for ANA but positive result for other antibodies.

Can you have sjogrens with negative ANA?

A negative ANA test does not exclude the diagnosis of Sjögren's syndrome; some of these individuals may still have SS-A and/or SS-B antibodies. With the immunofluorescent staining test, the pattern of nuclear staining is reported. Most Sjögren's patients have either a speckled or homogeneous pattern.

Understanding Autoimmune Disease

Can you have rheumatoid arthritis with a negative ANA?

Antinuclear antibody (ANA) testing – A negative ANA helps exclude SLE and other systemic rheumatic diseases; the ANA may be positive in up to one-third of patients with RA.

Can you have lupus with negative ANA?

The test you will hear most about is called the antinuclear antibody (ANA) test. However, this is not a specific test for lupus. Most people with lupus will have a positive ANA test result. It is very rare, but it is possible to have a negative ANA test and still have lupus.

What are markers for autoimmune disease?

Antinuclear antibodies are markers for a number of autoimmune diseases, the most notable of which is systemic lupus erythematosus (Ferrell and Tan, 1985). Antibodies to specific nuclear constituents are high specific for certain collagen vascular diseases.

Can you have scleroderma with a negative ANA?

Approximately 95% of people with systemic scleroderma have a positive antinuclear antibody (ANA) test, but so do people with other autoimmune diseases (97% of people with lupus, as an example). People with localized scleroderma usually have negative ANA.

Does a negative ANA test mean no autoimmune disease?

A negative ANA result suggests the absence of many autoimmune diseases, but does not rule them out. Additional testing, for example with specific antibody tests, should be considered if clinically warranted (Table 2).

Can you have connective tissue disease with negative ANA?

A patient with a negative ANA is highly unlikely to have either SLE, MCTD, Sjögren's, or scleroderma.

Do all autoimmune diseases show up in blood tests?

1 There is no one test that can diagnose all 80 types of autoimmune diseases. 2 However, some blood tests can show whether there is an inflammatory process going on in your body, which is a characteristic of autoimmune diseases, and help point the way to the correct diagnosis.

How do you know if you have an autoimmune disease?

No single test can diagnose most autoimmune diseases. Your doctor will use a combination of tests and a review of your symptoms and physical examination to diagnose you. The antinuclear antibody test (ANA) is often one of the first tests that doctors use when symptoms suggest an autoimmune disease.

Can you have an undiagnosed autoimmune disease?

Misunderstood and Misdiagnosed

Autoimmune diseases are illnesses of the unknown -- the body attacks itself, the illnesses are often repeatedly misdiagnosed, and effective treatments are few, even after doctors do figure out what's wrong.

What are the 3 most common autoimmune diseases?

Common ones include lupus, rheumatoid arthritis, Crohn's disease and ulcerative colitis. Autoimmune diseases can affect many types of tissues and nearly any organ in your body.

Can autoimmune symptoms come and go?

For many autoimmune diseases, symptoms come and go, or can be mild sometimes and severe at others. When symptoms go away for a while, it's called remission. Flares are the sudden and severe onset of symptoms.

What tests can diagnose autoimmune diseases?

The antinuclear antibody test (ANA) is one of the first tests that physicians use when they suspect a patient may be showing symptoms of an autoimmune disorder. True to its name, this test screens for antinuclear antibodies, which are a category of antibodies that attack the healthy proteins within the cell nucleus.

Can you still have lupus with normal blood work?

Dr. Michael Lockshin: The diagnosis of lupus is never made by blood test alone, since some people have positive blood tests but no disease. To make a diagnosis of lupus, you need to have both symptoms and, generally, positive blood tests.

Can lupus be missed in blood tests?

Antinuclear antibody (ANA) test.

While most people with lupus have a positive ANA test, most people with a positive ANA do not have lupus. If you test positive for ANA , your doctor may advise more-specific antibody testing.

Can you have seronegative lupus?

Most of the SLE cases are seropositive which depend on positive test for antinuclear antibody (ANA), Lupus erythematous (LE) cells, and antibody to DNA but seronegative SLE cases also rarely can present with complications.

Does inflammation always show up in blood tests?

Blood tests which detect inflammation are not sensitive enough to diagnose serious underlying conditions, generating an 85% false positive rate and a 50% false negative rate when used for this purpose, according to new research.

Is ANA always positive in rheumatoid arthritis?

Since RA is an autoimmune disease, many people with RA have positive ANA tests. However, a positive test doesn't mean you have RA. Many people have positive, low-level ANA tests without clinical evidence of RA.

What is the gold standard for diagnosing rheumatoid arthritis?

Radiographic imaging: the 'gold standard' for assessment of disease progression in rheumatoid arthritis.

What bloodwork shows Sjogren's syndrome?

Certain blood tests can detect these. The anti-SSA (also called anti-Ro) or anti-SSB (also called anti-La) blood tests are the most specific ones for Sjögren's syndrome. Other autoantibody tests include antinuclear antibody (ANA) and rheumatoid factor (RF).
