Can you have a negative ANA test 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.
Can you have a false negative ANA test?
Although doctors often use the test to confirm a diagnosis of lupus, it can sometimes provide false-negative or false-positive results.
Can autoimmune disease not show 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.
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 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 negative ANA and still have lupus?
It is possible for people with lupus to have a negative ANA, but these instances are rare. In fact, only 2% of people with lupus will have a negative ANA. People with lupus who have a negative ANA test may have anti-Ro/SSA or antiphospholipid antibodies.
What if your ANA test is negative?
A negative test means that certain autoimmune diseases are less likely to be present. However, 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 for other antibodies.
Can you have lupus and it not show up in bloodwork?
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.
Does a negative ANA mean no autoimmune disease?
The diagnostic value of a positive ANA result depends on the condition (Table 1). 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).
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.
What does autoimmune fatigue feel like?
The fatigue from an autoimmune disease differs from the tiredness most people feel after long periods of work or exercise or when they haven't slept well. It's a feeling of exhaustion all the time that interferes with the ability to function.
Can you have Mctd with a negative ANA?
A patient with a negative ANA is highly unlikely to have either SLE, MCTD, Sjögren's, or scleroderma.
Is ANA negative normal?
ANAs can be found in approximately 5% of the normal population, usually in low titers (low levels). These people usually have no disease. Titers of 1:80 or lower are less likely to be significant. (ANA titers of less than or equal to 1:40 are considered negative.)

What is seronegative lupus?
Systemic lupus erythematosus (SLE) is an autoimmune syndrome that occurs most commonly in women during their reproductive years. Nephritis is known to be one of the most serious complications of SLE. Lupus nephropathy is frequently associated with ANA and anti-dsDNA antibodies.
What are the typical signs and symptoms of autoimmune diseases using lupus as an example?
The most common signs and symptoms include:
- Joint pain, stiffness and swelling.
- Butterfly-shaped rash on the face that covers the cheeks and bridge of the nose or rashes elsewhere on the body.
- Skin lesions that appear or worsen with sun exposure.
What labs are abnormal with lupus?
Complete Blood Count (CBC)
CBC provides information about the red blood cell (RBC), white blood cell (WBC), and platelet counts, and health of RBCs, all of which may be abnormal in lupus and may need treatment. Common issues are: Low RBC (hematocrit, hemoglobin). A normal hematocrit is 35-40%, hemoglobin 11.5-15.0.

What are the 3 most common autoimmune diseases?
According to The Autoimmune Registry, the top 10 most common autoimmune diseases include:
- Rheumatoid arthritis.
- Hashimoto's autoimmune thyroiditis.
- Celiac disease.
- Graves' disease.
- Diabetes mellitus, type 1.
- Rheumatic fever.
- Pernicious anemia/atrophic gastritis.
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. The immune system attacks hair follicles (the structures from which hair grows).
What blood tests are done to check for autoimmune disorders?
One blood test for autoimmune disease is C-reactive protein (CRP). Another test is ESR (erythrocyte sedimentation rate) - this is done to assess an inflammation that is not from an infection or due to other reasons. One of the most common blood tests for detecting autoimmune disorders is ANA (antinuclear antibodies).
How do you test for autoimmune disease?
“There's usually no single test to diagnose autoimmune disease. You have to have certain symptoms combined with specific blood markers and in some cases, even a tissue biopsy. It's not just one factor.” Diagnosis can also be difficult because these symptoms can come from other common conditions.
What test can be used to determine whether a patient has an infectious or autoimmune disease?
The antinuclear antibody (ANA) immunofluorescence assay (IFA) is a first-line screening test for patients with a suspected autoimmune disease. This test is the gold standard because of its high sensitivity compared to other assays.
