If ANA (antinuclear antibody) testing comes back positive, the next step is to have further testing to look for a specific, accompanying antibody. These tests may include anti-Ro, anti-La, anti-Smith, anti-dsDNA, anti-Smith, anti-SSA, anti-SSB, an anti-centromere, or an anti-histone to confirm or rule out an autoimmune disorder.
Depending on the specific results, additional tests such as a CBC (complete blood count) or emunoglobulin levels may be necessary to determine the underlying cause of the positive result. Additionally, further imaging or laboratory tests may be recommended to assess organ function or exclude underlying infections or cancer.
Finally, depending on the results, a referral to another specialist may be necessary to provide further management of the underlying health issue.

Should I worry if I test positive for ANA?
It is important to remember that a positive result for an antinuclear antibody (ANA) test does not necessarily mean that you have an autoimmune disorder or any other specific health condition. It simply indicates that your body has created antibodies against your own tissues.
This can be caused by a range of factors, including virus or bacterial infections, certain medications, or exposure to certain environmental triggers.
In order to determine whether the presence of antibodies means that you have an autoimmune disorder or not, further testing will be required. This may include other blood tests, imaging tests, or biopsy.
Your doctor may also recommend certain lifestyle modifications or medications which may help to reduce symptoms or reduce the risk of developing an autoimmune disorder.
Therefore, if you test positive for ANA, it is important to see your doctor and have further testing and evaluation done, as it is the only way to determine the cause and course of treatment, if necessary.
How serious is a positive ANA test?
A positive ANA test can be a very serious indicator of autoimmune disease and should always be taken seriously. While a positive ANA test does not necessarily point to a specific condition, it does signal that further testing needs to be done to confirm a possible medical issue.
Many conditions, including systemic lupus erythematosus, scleroderma, rheumatoid arthritis, Sjogren’s syndrome, and polymyositis, are associated with a positive ANA test. If a positive ANA test is the result, additional blood tests and a physical exam may be necessary to diagnose the exact cause.
It is also important to be aware that this test can produce false positives, so additional tests may be needed to narrow down the exact cause and determine an accurate diagnosis. Treatment and management options for conditions associated with a positive ANA will vary depending on the diagnosis, overall health, and other factors, so it is important to seek expert medical advice.
Is it common to have a positive ANA?
Yes, it is common to have a positive ANA (antinuclear antibody test). A positive ANA is usually the indication of an autoimmune disorder. There are more than 100 types of autoimmune disorders, including rheumatoid arthritis, lupus, multiple sclerosis, and scleroderma.
The antinuclear antibody test can be done for diagnostic or screening purposes. It’s common for people with autoimmune diseases to have a positive ANA, as it typically occurs when the body’s immune system starts to attack healthy cells.
It can also occur in people without autoimmune diseases, however, which is why a positive ANA needs further evaluation to determine any underlying condition. It’s important to speak to your doctor if you have a positive ANA so they can recommend additional tests to rule out any autoimmune disease.
What diseases does a positive ANA test indicate?
A positive ANA test result can indicate a variety of diseases, including systemic lupus erythematosus (SLE), mixed connective tissue disorder (MCTD), scleroderma, juvenile idiopathic arthritis (JIA), and Sjögren’s syndrome.
The ANA test typically looks for antibodies in the blood that are specific for certain autoimmune diseases, which are diseases that are caused by the immune system attacking the body’s own tissues. While a positive ANA test result does not definitively point to any one specific disease, it does indicate that further testing may be necessary to investigate the cause of the positive result.
For example, a positive ANA result may be followed up with tests for specific antibodies associated with a particular auto-immune disorder, so that a more accurate diagnosis can be made. It is important to note that ANA tests are not always an accurate indicator of disease, as a negative result does not necessarily rule out the presence of an auto-immune disorder.
Additionally, a positive result does not always indicate the presence of a disease, and so further testing is necessary to confirm a particular diagnosis.
What will rheumatologist do with positive ANA?
When a rheumatologist receives a positive ANA test result, they will use it to help diagnose a person’s underlying rheumatological condition. ANA stands for Anti-nuclear Antibodies and they are proteins that are produced by the body’s immune system and directed against one’s own body’s cells and tissues.
This test can sometimes help identify autoimmune diseases like systemic lupus erythematosus (SLE) or rheumatoid arthritis (RA). After the initial ANA test result returns positive, the rheumatologist will likely order more specific tests to confirm the diagnosis and identify autoantibodies associated with particular autoimmune diseases.
The rheumatologist may also order other tests, such as a complete blood count (CBC), to help diagnose the individual’s medical condition and guide treatment decisions. Monitoring of any symptoms, laboratory tests, imaging studies, and other specialized tests may also be requested to help inform the diagnosis.
Ultimately, the rheumatologist will develop a treatment plan, including lifestyle modifications and medications tailored to the individual’s specific needs, in order to best manage their condition.
What level of ANA indicates lupus?
The presence of antinuclear antibodies (ANA) in the blood can be an indicator of various autoimmune disorders, including lupus. A positive ANA test indicates the presence of these autoantibodies in the blood, though it does not necessarily confirm lupus.
Generally, the higher the ANA levels, the more likely that the patient has lupus. A level of 1:40 in an ANA test is usually considered positive for lupus and ideally should be confirmed with other tests.
In general, patients with a reading exceeding 1:160 are said to have a higher chance of having lupus. Furthermore, certain patterns of ANA staining may indicate systemic lupus erythematosus (SLE) with further testing and help to refine the diagnosis of lupus.
Can you have a positive ANA and not be sick?
Yes, it is possible to have a positive antinuclear antibody (ANA) test and not be sick. ANA tests measure levels of antibodies in a person’s blood and can detect autoimmune diseases, including lupus and rheumatoid arthritis.
However, having a positive ANA does not necessarily mean that a person is sick, as the test is not specific to any one condition. An individual may have a positive ANA, but not have any symptoms of an autoimmune disease.
This is known as a “seropositive” result.
In addition, many healthy individuals may have a positive ANA, as the test can sometimes be falsely positive. False positives can be caused by certain conditions such as viral infections, or simply just due to random chance.
Because of this, having a positive ANA test result doesn’t always mean a person is sick, which is why medical professionals usually recommend further testing—such as biopsy or imaging—to determine the underlying cause.
Can inflammation cause positive ANA?
Yes, inflammation can cause a positive ANA (antinuclear antibody). ANA is an antibody that reacts with certain proteins found inside the nucleus of cells. ANA testing is typically done as part of an autoimmune evaluation.
When an autoimmune condition is present, the immune system may “attack” the body’s own proteins, instead of foreign invaders, and produce antibodies to them. When the ANA reacts to these proteins, it is considered positive.
Inflammation, which is a response to physical or emotional stress, can trigger an autoimmune condition and, as a result, a positive ANA. In some cases, such as in people with lupus, the inflammation can cause a long-term, or even permanent, positive ANA.
Other causes of inflammation, such as an infection, may only produce a temporary, or “transient,” positive ANA. It is important to have a thorough evaluation to determine the exact cause and ensure that appropriate treatment is provided.
What blood tests are done for autoimmune diseases?
A wide array of blood tests can be done to diagnose an autoimmune disorder. The tests can involve looking at specific types of white blood cells and to measure the level of inflammation in your body.
In addition, there are tests that look for autoantibodies which are the proteins that your immune system produces to fight off foreign material. Tests for autoantibodies can help confirm the diagnosis of an autoimmune disorder.
Other tests that are often ordered are a comprehensive metabolic panel (CMP) which can help determine if other organs have been affected or testing to investigate if chronic inflammation is present. A number of thyroid tests that measure the levels of hormones produced by the thyroid can also be done to help diagnose autoimmune thyroid diseases.
Finally, testing for deficiency of vitamins and minerals can be done to determine if nutritional deficiencies are associated with the autoimmune condition.
Overall, the results of blood tests can give providers important information to make a diagnosis, to help decide on the course of treatment, and to track how the disorder is responding to treatment.
Can a positive ANA be something other than lupus?
Yes, a positive ANA can be something other than lupus. A positive ANA result simply means that autoantibodies are present in the person’s bloodstream. Autoantibodies are proteins produced by the immune system that mistakenly attack the body’s own tissues.
A positive ANA test can be due to a variety of other circulating autoantibodies from different disease processes.
These include rheumatoid arthritis, autoimmune pernicious anemia, juvenile arthritis, autoimmune thyroid disease, scleroderma, myositis, Sjögren’s syndrome, inflammatory bowel disease, polymyositis, and also drug-induced lupus.
Additionally, antigen-antibody complexes can sometimes cause a positive ANA that are not related to an underlying autoimmune condition. Therefore, even though a positive ANA may lead to suspicion of lupus, it can instead be indicative of another condition or no conditions at all.
What labs are elevated with lupus?
When diagnosing lupus, there are several lab tests that physicians use to check different markers. These tests can help determine whether a patient has antibodies associated with systemic lupus erythematosus (SLE) and can also help detect inflammation.
Some of the common labs that can be elevated with lupus include:
1. Erythrocyte sedimentation rate (ESR): The ESR measures how quickly red blood cells settle out of a tube of unclotted blood. An elevated ESR can indicate inflammation, which can be present in lupus.
2. C-reactive protein (CRP): CRP is a protein produced by the liver in response to inflammation. An elevated CRP level can be associated with active lupus.
3. Antinuclear antibodies (ANA): ANAs are antibodies that are often associated with lupus and other autoimmune diseases. An elevated ANA test result can indicate the presence of certain proteins commonly seen in lupus.
4. Complement levels: Complement proteins are important in the inflammatory response and can become elevated in lupus. Low complement levels can be associated with lupus nephritis, a serious kidney disorder that can occur in lupus patients.
5. Anti-double stranded DNA (anti-dsDNA): Certain antibodies, including anti-dsDNA, are typically seen in lupus. An elevated level of this antibody indicates active lupus.
Additionally, patients with lupus may have their kidney and liver function tests checked for signs of active disease. In some cases, thyroid testing may need to be done. Determining how severe the lupus is can also be done using a lupus disease activity index, which scores inflammation and organ involvement.
What autoimmune disease does a rheumatologist treat?
A rheumatologist is a medical doctor who specializes in treating autoimmune diseases, which are illnesses caused by a misdirected immune system that attacks the body’s own tissues and organs. Examples of autoimmune diseases that a rheumatologist might treat include rheumatoid arthritis, lupus, ankylosing spondylitis, psoriatic arthritis, Sjögren’s syndrome, gout, immune-mediated vasculitis, scleroderma, and myositis, among others.
Diagnosis and treatment of autoimmune diseases often involves the use of medications and other therapies such as physical therapy and counseling, and in some cases, surgery may be necessary. A rheumatologist might also diagnose and treat osteoarthritis, a condition caused by the wearing away of the joint cartilage, as well as other pains and stiffness in the muscles and joints, and some types of skin conditions.
Can a positive ANA mean rheumatoid arthritis?
Yes, a positive ANA (anti-nuclear antibody) test can be used to indicate the possibility of rheumatoid arthritis. ANA tests are used to detect autoimmune disorders, and rheumatoid arthritis is one of these disorders.
A positive ANA test occurs when antibodies produced by the immune system attack the body’s own cells and tissues. If the ANA test comes back positive, it can be an indication that the body is suffering from an autoimmune disorder.
However, a positive ANA test does not necessarily mean that a person has rheumatoid arthritis. Other autoimmune disorders, such as lupus, may be indicated by a positive test as well. Additional tests, such as rheumatoid factor and anti-cyclic citrullinated peptide tests, may be used to confirm a diagnosis of rheumatoid arthritis.
Do I have lupus if my ANA is positive?
As anyone familiar with lupus knows, there is no single diagnostic test for this autoimmune disorder. Therefore, if you have a positive ANA (antinuclear antibodies) test, it does not necessarily mean that you have lupus.
While a positive ANA test can be an indicator of lupus in people who have certain symptoms, it is not a definitive diagnosis on its own. Depending on the result, your doctor may want to perform more tests to determine a specific diagnosis.
In general, an ANA test is used as a first step to diagnose autoimmune diseases like lupus. If the ANA test is positive in someone with suggestive symptoms, then your doctor may recommend a series of additional lab tests to help diagnose lupus, including anti-DNA and anti-Sm tests, a complement level test, and a more specific immune system test.
A physical exam and medical history may also be taken into consideration.
If you have a positive ANA test, it is important to talk to your doctor and see if any additional testing is necessary to help diagnose or exclude lupus. It is important to remember that even if your ANA test shows positive, it does not necessarily mean you have lupus.
