In order to check for lupus, your doctor will need to perform a variety of tests. These tests may include a physical examination, blood tests, urine tests, imaging tests and a biopsy.
During the physical exam, your doctor will check your joints and skin for swelling, tenderness and discoloration, look for the ‘butterfly’ rash which is associated with lupus, and evaluate and monitor other lupus symptoms.
Blood tests an be used to diagnose lupus or to monitor the progression of the condition if already known to be present. Common blood tests include a complete blood count (CBC), urine tests such as a urine protein or urine sediment exams to check for the presence of inflammation, and antinuclear antibody (ANA) tests to check for the presence of antibodies produced by the immune system.
Imaging tests, such as X-rays, ultrasound, or magnetic resonance imaging (MRI), can be used to detect inflammation, check for organ changes, and confirm a diagnosis.
Finally, a biopsy may be necessary to confirm a lupus diagnosis. During a biopsy, a sample of tissue from the organs or skin is removed to examine under a microscope for evidence of lupus.
In some cases, these tests may be inconclusive and a combination of these tests may be used to confirm a lupus diagnosis.

What tests are done to check for lupus?
There are a variety of tests and exams that can be done to help diagnose lupus. These include (but are not limited to):
Blood Tests: Blood tests can be used to check for signs of inflammation, as well as lupus antibodies. Examples of some lupus antibodies that may be tested for include anticardiolipin antibodies, anti-nuclear antibodies (ANA), and anti-double stranded DNA (anti-dsDNA).
Urinalysis: A urinalysis is the testing of urine for signs of inflammation, such as white blood cells and protein.
Imaging Tests: Imaging tests such as X-rays and ultrasounds can be used to check for changes in organs, as well as any swelling or tenderness. Magnetic resonance imaging (MRI) and computed tomography (CT) scans can also be used to detect organ damage.
Cutaneous Lupus Tests: If a patient is suspected of having cutaneous lupus, a doctor may recommend an intact skin biopsy to check for signs of inflammation or damage.
Lupus Tests for the Kidneys: Special kidney tests may be recommended if lupus is suspected to be affecting the kidneys. These tests may include a urinalysis, complete blood count (CBC), comprehensive metabolic panel (CMP), and a uric acid test.
These tests and exams can help a doctor diagnose lupus and rule out other conditions. It is important to speak with a doctor if you think you may have any symptoms of lupus.
What blood tests would indicate lupus?
There are a variety of laboratory tests that can be used to help diagnose lupus and determine its severity, such as:
1. ANA Test – this test checks for antibodies in the blood that are associated with lupus. It is one of the most commonly used tests used to help diagnose lupus.
2. Erythrocyte Sedimentation Rate (ESR) – this is a measurement of how quickly the red blood cells separate out from the blood when placed into a test tube. An increased level of ESR can be a sign of inflammation or infection.
3. Complement Levels Test – this test checks the level of proteins in the blood that help defend against infections. Low levels of these proteins can be associated with lupus.
4. Anti-dsDNA Test – also known as a double stranded DNA test, this test measures specific antibodies that only appear in people with lupus.
5. Creatinine Test – this test measures a waste product in the blood that can be used to help measure kidney function. People with lupus are at an increased risk of developing kidney complications.
6. Platelet Count Test – this test measures the number of platelets in the blood, which help stop bleeding. People with lupus may experience decreased platelet count due to inflammation from lupus.
What are the 11 markers for lupus?
The 11 markers of lupus include specific autoantibodies, changes in the complement levels in the blood, a variety of hematological presentations, and presence of LE cells.
The presence of one or more of these 11 markers can help to diagnose lupus, but they are not completely definitive on their own.
1. Antinuclear Antibodies (ANA): These autoantibodies circulate throughout the body, binding to the nuclei of cells and increasing the risk of tissue destruction.
2. Anti-DNA: These autoantibodies target the DNA inside cells, disrupting the normal functioning of the cell.
3. Anti-Smooth Muscle Antibodies (ASMA): These autoantibodies are present in some people with lupus and can attack the smooth muscle cells of the body, leading to scarring and destruction.
4. Antiphospholipid Antibodies (aPL): These autoantibodies bind to and disrupt certain types of phospholipids, or fats, found in the blood.
5. Decreased Complement Levels: Lupus is associated with a decrease in the overall levels of certain components of the complement system, an important part of the body’s natural defense system.
6. C-Reactive Protein: This is a protein made by the liver in response to inflammation or infection in the body.
7. Hemoglobinuria: The presence of abnormally high levels of hemoglobin, a protein in red blood cells, in the urine.
8. Leukopenia: A decrease in the number of white blood cells in the body, which can decrease the body’s ability to fight off infection.
9. Thrombocytopenia: A decrease in the number of platelets, which are needed to form a clot and prevent excessive bleeding.
10. Coombs’ Test: An antibody test that reveals the presence of autoantibodies against red blood cells, which can cause destruction of red blood cells.
11. LE Cells: An abnormal form of white blood cell that can be found in persons with lupus, which is indicative of inflammation.
What is included in a lupus panel?
A lupus panel is a diagnostic blood test used to diagnose and monitor lupus. This test checks for different substances that can indicate an autoimmune condition such as lupus, including antinuclear antibodies (ANA), anti-double stranded DNA antibodies (anti-dsDNA), anti-phospholipid antibodies, complement levels, and white blood cell count.
The ANA test is used to measure the presence of autoantibodies that can damage various organ systems. The anti-dsDNA antibodies test is used to detect antibodies that could potentially cause inflammation in the kidneys.
The anti-phospholipid antibodies test is used to detect the presence of antibodies that can lead to an increased risk of clotting disorders. The complement levels test is used to measure the levels of proteins involved in the regulation of inflammation and the white blood cell count test is used to measure the number of white blood cells in the body which can suggest an activated immune system.
By obtaining the results of these tests, those with suspected lupus can be properly diagnosed and monitored. All of the tests are performed in a laboratory and the results are generally available within 5-7 days.
What is the gold standard for diagnosing lupus?
The gold standard for diagnosing lupus is a combination of clinical assessment and a variety of laboratory tests. Diagnosis typically includes a complete physical examination and a review of family and personal medical history, followed by a physical examination and a variety of tests.
Laboratory tests used to diagnose lupus include a complete blood count (CBC) to measure levels of red and white cells and platelets in the blood, a C-reactive protein (CRP) test to measure inflammation, an antinuclear antibody test (ANA) to detect antibodies to proteins in the blood, and a sedimentation rate (ESR) to measure the rate of red blood cell sedimentation.
Other tests used to diagnose lupus include urine tests, X-rays, and biopsies of any suspicious areas.
To determine a final diagnosis, doctors and scientists use a complex system of criteria known as the Systemic Lupus Erythematosus (SLE) criteria. This criteria is based on the American College of Rheumatology and includes eleven components that need to be present in order to make a reliable diagnosis.
Examples of these components include clinical signs and symptoms, duration, and results of laboratory tests. If a patient meets four or more of these criteria, they can be diagnosed with lupus.
Does lupus show up in routine blood tests?
No, lupus typically does not show up in routine blood tests. To diagnose lupus, a doctor may run a series of blood tests such as a complete blood count (CBC), antinuclear antibody (ANA) test, and erythrocyte sedimentation rate (ESR) test.
A CBC detects any underlying infection or anemia. The ANA looks for autoantibodies found in those with lupus. The ESR test measures the time it takes for red blood cells to settle in a tube, which is higher in people with inflammatory conditions.
Other helpful tests can include a urinalysis or a chest x-ray. Ultimately, the diagnosis of lupus may involve an assessment of a person’s medical history and physical examination in addition to laboratory tests.
What is the hallmark symptom of lupus?
The hallmark symptom of lupus is a butterfly-shaped rash across the bridge of the nose and cheeks. This butterfly rash is called a malar rash and is often the first sign of lupus. Other symptoms associated with lupus can vary, but may include joint pain, chest pain, fatigue, fever, and the presence of other skin rashes.
In some cases, patients may alsodevelop kidney symptoms, such as protein or blood in the urine, or experience abnormal blood test results. Because lupus can affect many different parts of the body, diagnosis can take time.
Additionally, symptoms may come and go, making diagnosis even more difficult. It is important to talk to a medical professional for proper diagnosis of lupus.
What are the early signs of lupus in females?
There are numerous subtle early warning signs of lupus in females. General fatigue, an unexplained fever, body aches, swollen and painful joints, headaches, and skin rashes are all common symptoms that can indicate the possible presence of lupus.
More specifically, there are a few conditions women with lupus may experience that can appear before other symptoms.
In some cases, a person may experience Raynaud’s phenomenon, which is a condition characterized by discoloration of the extremities (fingers and toes) in response to cold temperatures or stress. This manifests as a reddening of the skin and can be accompanied by a tingling sensation.
Another tell-tale sign of lupus is a type of skin rash known as a butterfly rash. The rash appears as a red, scaly patch of skin on both cheeks, extending from the nose to the sides of the face. This rash is caused by inflammation of the capillaries of the skin, which is also a characteristic of Lupus.
Finally, large patches of discoloration (hyperpigmentation) can appear on the face, often in the form of blotches or small dots. This is commonly referred to as a lupus “malar” rash and is an indication that the autoimmune system is beginning to attack healthy tissue.
These are all potential signs that should be discussed with a medical professional, especially if they are accompanied by other lupus symptoms. Prompt diagnosis and treatment can reduce the risk of long-term damage.
What test does a rheumatologist do for lupus?
A rheumatologist may perform a range of tests for lupus to confirm a diagnosis. These tests may include:
• Complete Blood Count: This test looks for abnormalities such as anemia, a low platelet count and a high white blood cell count.
• Urine Test: This test checks for the presence of proteins, red blood cells and other signs of inflammation that may indicate the presence of lupus.
• Anti-nuclear Antibody (ANA) Test: This blood test looks for antibodies that attack the body’s own tissues, which can be an indication of lupus.
• Anti-dsDNA and Anti-Sm Tests: These blood tests look for antibodies to double-stranded DNA (dsDNA) and Smith (Sm) antibody, which can be indications of lupus.
• Complement Tests: This blood test measures the level of C3 and C4 proteins in the body, which can indicate how active the disease is.
• X-ray, CT Scan or Magnetic Resonance Imaging: These imaging tests can provide the doctor with visual clues of inflammation and will help them diagnose and monitor the progress of the condition.
• Other Lab Tests: These tests look for certain compounds in the blood, such as lupus anticoagulant.
Your rheumatologist may also perform a physical exam and review your medical history to confirm a diagnosis.
Which test is the most sensitive in diagnosing systemic lupus erythematosus?
The most sensitive test for diagnosing systemic lupus erythematosus (SLE) is an antinuclear antibody (ANA) test. This test is used to detect the presence of autoantibodies, or antibodies the immune system mistakenly produces against its own organs and tissues, in the blood.
When autoantibodies are present, they can bind to and damage healthy tissue leading to autoimmune diseases, such as SLE. ANA tests are very sensitive, meaning they can detect the presence of autoantibodies even when the levels present in the blood are low.
In the case of SLE, an ANA test is often the first step in diagnosis. Other tests, such as immunoglobulin levels and additional autoantibody tests, may be repeated if the initial ANA test is positive and further confirm or refute a diagnosis of SLE.
How do lupus symptoms start?
Lupus symptom onset can vary from person to person, but usually the early warning signs start slowly and then become more noticeable over time. Generally, the most common early symptoms of lupus are extreme fatigue, joint pain, unexplained fevers and rashes (most commonly a butterfly or malar rash on the nose and cheeks).
Other common signs and symptoms that may be seen in the first few months or years of lupus disease can include kidney problems, chest pain, hair loss, anemia, upset stomach, decreased appetite, sensitivity to sunlight, headaches and depression.
Some people may also have difficulty focusing, memory problems or symptoms that mimic a stroke, such as confusion, slurred speech and loss of balance. Additionally, some individuals may experience organ involvement in the early stages of lupus, such as an abnormally enlarged spleen, blood vessel inflammation and extreme changes in white blood cells.
When lupus is coupled with other conditions, such as Sjogren’s Syndrome, various neurological and psychological symptoms can also present in the early stages. It is important to seek medical attention for any changes in your physical or mental health, as early diagnosis and treatment can help you to reduce any long term complications from the disease.
What does the beginning of a lupus flare feel like?
The onset of a lupus flare can vary widely, depending on the individual, but some of the most common symptoms include fatigue, pain and stiffness, particularly in the joints, as well as a general feeling of illness, similar to the flu.
Other signs may also appear, such as a butterfly-shaped rash over the nose and cheeks, high fever, and chest pain. Ultimately, the signs of a lupus flare depend on the individual and the specific type of lupus they have.
Some individuals may have organ involvement, and others may experience symptoms that affect the skin, musculoskeletal system, and/or the nervous system. For some, the onset of an attack may come on gradually and be difficult to pinpoint, while for others, it can come on suddenly and with severity.
It is important to remember that the onset and the experience of lupus can differ drastically between individuals.
What triggers onset of lupus?
The exact triggers for the onset of lupus are not yet known, although a variety of environmental factors, such as infectious agents and ultraviolet light, may play a role. Genetics also plays a role in determining who is likely to develop lupus and its severity.
Certain genes may make individuals more sensitive to environmental factors that can trigger lupus, such as ultraviolet light. Other potential triggers may be hormonal factors, medications, or chemicals in the environment.
For example, some people may experience a lupus flare-up after taking antibiotics, or after being exposed to certain chemicals. Stressful events, such as the death of a loved one, have also been linked to lupus flares in some individuals.
Can you have lupus and not know it?
Yes, it is possible to have lupus and not know it. Lupus is a chronic autoimmune disorder, which means its symptoms can often vary in intensity. As a result, some people may have mild symptoms that they may not recognize as signs of lupus, while others may have more serious symptoms that they may think are something else.
Additionally, lupus is an illness where inflammation and damage can occur in any organ, making it difficult to diagnose. The most common symptom of lupus is a butterfly-shaped rash that appears on the cheeks and the bridge of the nose.
However, this symptoms may be overlooked in some people or may present itself in different ways, such as having raised red patches on the arms, legs, hands and feet. Other common lupus symptoms may include fever, sensitivity to sunlight, painful or swollen joints, extreme fatigue, chest pain, hair loss and other skin rashes.
Fortunately, there are now tests that can be done to help diagnose lupus and a doctor should be consulted if someone is showing symptoms.
