- Antinuclear Antibody Test (ANA Test) The ANA test is the most common test for lupus. However, antinuclear antibodies can also test positive in several other autoimmune conditions. Because of this, dsDNA has been added to this lupus blood test. Anti-Double Stranded DNA Test (dsDNA) dsDNA is simular to ANA, howerver, it is highly specific for lupus.

- Highlights. 1  An ANA test is used to help determine whether someone has an autoimmune disorder, such as lupus or rheumatoid arthritis. 2  The ANA test is a simple blood test that finds the presence of antibodies that mistakenly attack healthy proteins in the body. 3  The ANA test can’t diagnose you with a specific condition.

Blood Tests to Diagnose Arthritis Another test for rheumatoid arthritis that measures levels of antibodies that bind citrulline modified proteins (anti-CCP) is more specific and tends to be elevated in patients with rheumatoid arthritis or in those about to develop rheumatoid arthritis.

Lupus Blood Tests [The absence of anti-dsDNA, however, does not exclude a diagnosis of lupus.] The presence of anti-dsDNA antibodies often suggests more serious lupus, such as lupus nephritis (kidney lupus). When the disease is active, especially in the kidneys, high amounts of anti-DNA antibodies are usually present.

Lab tests for lupus Many different laboratory tests are used to detect physical changes or conditions in your body that can occur with lupus. Each test result adds more information to the picture your doctor is forming of your illness. The most common types of tests you may be asked to get are blood and urine tests.

Adapted from a presentation at the SLE Workshop at Hospital for Special Surgery It is important to note that a positive anti-DsDNA does not always guarantee a diagnosis of lupus. Some people fluctuate between positive and negative anti-DsDNA test results. A diagnosis of lupus is always based on physical presentation and symptoms of the patient in combination with lab test results.

- 1 Lab work alone cannot diagnose lupus. 2  97 percent of those with lupus will have a positive antinuclear antibody test (ANA). 3  It’s common for positive lab tests to come and go over time. 4  If this happens, it’s less likely that you will receive a lupus diagnosis, although it remains possible.hospholipids found in lupus are also found in syphilis, and the blood test cannot always tell the difference between the two diseases. A positive result to a syphilis test does not mean that you have or have ever had syphilis.

Cardiolipin Antibody A cardiolipin antibodies test looks for a certain kind of antibody in your blood. The antibodies are IgG (immunoglobulin G), IgA (immunoglobulin A), and IgM (immunoglobulin M).They are antibodies that form in response to cardiolipins. Cardiolipin is a phospholipid, or a kind of fat in the blood.he cardiolipin antibodies test is usually just one of many tests given. The tests you get will depend on what your healthcare provider is looking for. For example, if your doctor thinks you have lupus, you will probably need other blood tests.

Antibody Tests for Autoimmune Disorders Blood tests for the following autoantibodies are often performed to aid in the diagnosis of autoimmune disorders: Antinuclear antibody is present in almost all people with systemic lupus erythematosus (SLE) a generalized autoimmune condition that attacks a number of different tissues.ntiphospholipid antibody, which is associated with blood clot formation and miscarriages, may be present in SLE and certain other autoimmune conditions. Anti-smooth muscle antibody, frequently present in patients with chronic active hepatitis, aids in distinguishing between this and other forms of liver disease.

- The antinuclear antibody (ANA) test is used evaluate for autoimmune disorders and to diagnose systemic lupus erythematosus (SLE). The ANA test is ordered when someone shows signs and symptoms that are associated with a systemic autoimmune disorder.

What do my blood tests mean? Complete blood count. This test measures the number of red blood cells, white blood cells and platelets as well as the amount of hemoglobin, a protein in red blood cells. Results may indicate you have anemia, which commonly occurs in lupus. A low white blood cell or platelet count may occur in lupus as well. Erythrocyte sedimentation rate. This blood test determines the rate at which red blood cells settle to the bottom of a tube in an hour. A faster than normal rate may indicate a systemic disease, such as lupus.

Lupus Anticoagulant (LA): A Laboratory Testing Algorithm [Utilization Spotlight] In most situations, LA testing cannot be reliably performed to detect or exclude LA when these anticoagulants are present, and there is risk of false-positive results. Summary. Laboratory testing for the presence of a lupus anticoagulant is challenging and interpretation must be carefully evaluated. The available laboratory assays and methods exhibit differences in their ability to detect a lupus anticoagulant, and no single laboratory test is capable of detecting them all.

Laboratory Evaluation of Rheumatic Diseases Anti-Sm antibodies are very useful for confirming the diagnosis of SLE. A positive test result strongly supports the diagnosis, although a negative test result cannot exclude it. The sensitivity of anti-SM antibody for diagnosis of lupus ranges from 24% to 30%, and specificity ranges from 96% to 98%.

Can You Have Lupus With Negative ANA Test Results? A positive ANA isn’t specific for lupus, since the test can also be positive with other autoimmune diseases as well. If an ANA test is negative, the diagnosis of SLE is less likely, but the small possibility of having the disease is still there.ind out if you can have lupus with negative ANA test results. slide 1 of 5. An ANA test is a blood test used to screen for autoimmune diseases such as systemic lupus erythematosus, or SLE.

- An anti-dsDNA test may be ordered along with a test for anti-Sm (Smith antibody), another antinuclear autoantibody associated with lupus, to help establish a diagnosis. The anti-Sm test may be ordered as part of an extractable nuclear antigen (ENA) panel.

Lupus Anticoagulant Testing Lupus anticoagulant testing is a series of tests used to detect lupus anticoagulant (LA) in the blood. LA is an autoantibody associated with excess blood clot formation. LA testing may be used to help determine the cause of: An unexplained blood clot (thrombosis) in a vein or artery. Recurrent miscarriages.

Lab tests for lupus Lab work alone usually cannot diagnose lupus. Signs and symptoms of the disease are also important. When a positive antinuclear antibody (ANA) test is accompanied by several other clues that doctors look for in diagnosing lupus, it is often a strong indication for doctors to consider lupus.

- Lupus is chronic and complex, and is often difficult to diagnose. There is no single laboratory test that can determine if a person has lupus. To complicate matters, many symptoms of lupus are similar to those of other diseases, and can come and go over weeks and months. It can often take years for a diagnosis to be made. To diagnose lupus, a doctor should be able to find physical or laboratory evidence of the condition, such as swelling of joints, protein in the urine, fluid around the lungs or heart, or a skin biopsy (test of a sample) that shows evidence of the disease.

Lupus: Diagnosis and Classification Diagnosis of lupus can be problematic. Making a correct diagnosis of lupus requires knowledge and awareness on the part of the doctor and good communication on the part of the patient. The most useful tests to aid a diagnosis identify certain autoantibodies often present in the blood of people with lupus.
