When diagnosing lupus, medical professionals usually look at a combination of physical symptoms and blood tests. An increased presence of antinuclear antibodies (ANA) along with other biomarkers can indicate lupus.
According to the Mayo Clinic, levels of inflammatory proteins, such as erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are generally elevated in patients with lupus. Other signs of lupus that might show up on a blood test include decreased levels of white and red blood cells, as well as lower-than-normal levels of blood platelets, which can lead to heavy bleeding.
In order to diagnose lupus, additional laboratory tests may also be necessary. These can include tests to measure the levels of complement components in the blood, along with immune cell markers, such as anti-double-stranded DNA (anti-dsDNA), antiphospholipid antibodies (aPL), anti-Ro/anti-La, and antineutrophil cytoplasmic antibodies (ANCA).
Other signs of lupus, including anemia and kidney problems, can also be identified through laboratory tests.

What labs are elevated with lupus?
Lupus is an autoimmune disorder, which means that the body’s immune system mistakenly attacks its own organs and tissues. People with lupus can experience a wide variety of signs and symptoms, including fever, joint pain, fatigue, and skin lesions.
Blood tests can help diagnose lupus and determine how severe the disorder is.
Several blood tests are commonly used to diagnose lupus. These tests can measure the levels of certain proteins and antibodies in the blood, which can indicate whether an autoimmune disorder is present.
Generally, elevated levels of these lab tests can indicate lupus:
• ANA test (antinuclear antibody): This test looks for antibodies that attack the nuclei of cells.
• Anti-double-stranded DNA (dsDNA): This test looks for antibodies that attack the DNA of cells.
• Anti-Ro (SSA) and Anti-La (SSB) antibodies: These tests look for antibodies that attack components of the immune system.
• Complement tests: These tests measure the levels of proteins in the blood that are involved in inflammation.
• C3 and C4 tests: These tests measure the levels of proteins in the blood that are involved in fighting off infections.
In addition to these lab tests, a doctor may also use other tests, such as a chest X-ray and ultrasound, to diagnose lupus. All of these tests can help determine if a person has lupus and how severe the condition is.
What are the 11 markers for lupus?
The 11 markers for lupus are:
1. Swollen and/or tender joints.
2. Systemic Lupus Erythematosus (SLE) Antibody.
3. Proteinuria.
4. Cutaneous lupus erythematosus (CLE).
5. Nervous system involvement.
6. Positive ANA (antinuclear antibody) test.
7. LowCount erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP).
8. Photosensitivity (sensitivity to UV light).
9. Hemolytic anaemia (lower than normal hemoglobin levels).
10. Malar Rash (a characteristic butterfly-shaped rash found around the nose and cheeks).
11. Immune complex deposition in the skin and other organs.
The majority of these markers need to be seen by a physician and tested through blood work, X-rays, and biopsies to make a definitive diagnosis of lupus. As lupus symptoms can be very broad, a range of tests may need to be done in order to confirm and identify the disease.
What labs are in a lupus panel?
A lupus panel typically includes a variety of different laboratory tests to help diagnose and monitor the condition. These tests can include a complete blood count (CBC) to check for inflammation and a serum complement test to measure proteins that regulate the immune system, such as C3 and C4.
It might also include an antinuclear antibody (ANA) test, which detects the presence of proteins that suggest an autoimmune disorder like lupus is present. Additionally, the panel might also include a rheumatoid factor (RF) test to help diagnose rheumatic diseases, a urine test for protein and blood, and a urinalysis to check for kidney involvement.
In certain cases, a doctor might order an evaluation of inflammatory markers such as erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) to help diagnose lupus. It is important to note that the specific tests included in a lupus panel can differ based on the individual patient’s symptoms, health history, and other factors.
What indicates lupus in bloodwork?
Including a complete blood count (CBC), erythrocyte sedimentation rate (ESR), creatinine, antinuclear antibody (ANA) test, anti-dsDNA, anti-Ro and anti-La, and antiphospholipid antibody (APLA) tests.
The CBC looks at the red and white blood cell counts, as well as the hemoglobin, hematocrit, and other red and white cell indices, to determine if there is anemia or other signs of inflammation. The ESR is often elevated in lupus and other inflammatory conditions.
Creatinine measures kidney function, which can be compromised by lupus. The ANA test looks for the presence of antinuclear antibodies, which are specific to lupus, in the blood. The anti-dsDNA, anti-Ro and anti-La, and APLA tests look for other auto-antibodies, which are also found only in lupus.
An elevated result of any of these blood tests can indicate lupus. Other tests that can be used to diagnose lupus include urinalysis, chest x-rays, and anti-Sm antibody tests.
Would lupus show up on a CBC?
Yes, depending on the type of lupus someone has and the symptoms they are experiencing, a complete blood count (CBC) can provide insight into the presence of lupus. The CBC will look at the amount of red and white blood cells in the body, which can be an indicator of the disease.
For example, a decrease in white blood cells may indicate an autoimmune disorder such as lupus, while an increase in red blood cells may point to a deficiency in the bone marrow that can be caused by lupus.
In addition, lupus can affect the levels of hemoglobin and platelets in the blood, which can be detected through a CBC. Anemia is often associated with lupus, and a decrease in the amount of hemoglobin can be detected via a CBC.
Finally, elevated levels of certain inflammatory proteins in the blood, such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), can also be used as markers for lupus.
What is the classic symptom of lupus?
One of the most commonly recognized classic symptoms of lupus is a butterfly-shaped rash on the cheeks and across the bridge of the nose. This rash, referred to as the malar rash, is a tell-tale sign of lupus, and is usually red, scaly, and partially raised above the skin.
Another classic symptom of lupus is significant fatigue, which is usually a side effect of any of the other symptoms or problems caused by the disease. Another common symptom of lupus is joint and muscle pain, particularly in the hips, arms, and shoulders.
In some cases, patients may also experience chest pain and difficulty breathing due to inflammation of the lining of the lungs. A decreased amount of red and white blood cells, which can be detected with a simple blood test, is one of the hallmarks of the disease.
In females, lupus may cause irregular periods, painful intercourse, and even infertility. Finally, lupus can also cause some neurological disturbances, such as confusion, difficulty concentrating, and seizures.
What level of ANA indicates lupus?
A positive antinuclear antibody test, or ANA test, is used to help determine if a person has autoimmune diseases like lupus. In this test, a blood sample is taken and tested for antinuclear antibodies, or ANAs.
A positive result on an ANA test indicates that antibodies are present in the blood that are attacking body cells and tissues, a sign of an autoimmune disorder.
A range of ANA levels can be seen in people with lupus, depending on the severity of the disease, and the level may vary over time. Generally, when a positive ANA test exists, levels above 1:160 are usually associated with lupus, although a lower level could indicate lupus in some cases.
Levels that are higher than 1:160 are more likely to indicate lupus, and are also more likely to mean that the disease is active.
Can routine blood test detect lupus?
Yes, routine blood tests can be used to detect lupus. These tests, which are sometimes called serologic tests, measure the levels of antibodies in the body. Antibodies are produced by the immune system as a way to protect the body from infection and disease.
When lupus is present, the body produces antibodies, which can then be detected in a routine blood test. Common serologic tests for lupus include antinuclear antibody (ANA) tests, anti-dsDNA/Sm tests, SLE antibody tests, and anti-Ro/SSA tests.
These tests can detect the presence of lupus even when symptoms are not present, which is why they are essential in diagnosing the condition. The results of these tests should be interpreted along with a physical exam and clinical history in order to accurately diagnose lupus.
What would CBC look like with lupus?
If a person has been diagnosed with lupus, their CBC looks different than typical results. Generally, the white blood cell count will be lower than normal and the red blood cell count will be higher.
The composition of the red blood cells may also be abnormal, as the red cells can sometimes be smaller and paler in color. Platelet counts may also be slightly lower than normal. Additionally, someone with lupus may have anemia, which is marked by a low hemoglobin and hematocrit level, along with a high mean corpuscular volume (MCV) which indicates that the red blood cells are larger than normal.
In some cases, a person with lupus may also have elevated levels of certain inflammatory markers, such as C-reactive protein and erythrocyte sedimentation rate. In extreme cases, a person with lupus may also have signs of leukopenia or low white blood cell count.
This is generally a sign of an autoimmune disorder or infection, and is treated with immunosuppressive medications.
How do rheumatologists diagnose lupus?
Rheumatologists diagnose lupus through an extensive process of evaluation, physical examination, laboratory tests, evaluation of symptoms, and imaging studies.
The process of diagnosis begins with a thorough physical examination. The doctor will check for any signs and symptoms of the condition, including swollen and tender joints, a rash, fever, and fatigue.
They may also feel for any swollen lymph nodes or organs.
The doctor may also perform laboratory tests, such as a complete blood count and a urinalysis. These tests can reveal the presence of certain conditions, such as high levels of inflammation that may indicate lupus.
Antibodies in the blood can provide further evidence that the symptoms may be caused by lupus.
The doctor will also speak with the patient about any other symptoms. They may ask about when the symptoms first occurred, any activities that cause the symptoms to worsen, any medications being taken for them, and any other medical conditions that exist.
Imaging studies may also be used to diagnose lupus. X-rays, CT scans, MRIs and ultrasounds can help the doctor identify any changes that may be present that could indicate the presence of lupus. For example, X-rays can reveal any calcium deposits that may be present due to inflammation.
In some cases, a biopsy may be necessary. The doctor will take a sample of tissue, such as a piece of skin or cartilage, and examine it under a microscope. This will help them determine if the symptoms are due to lupus or another condition.
Overall, diagnosing lupus requires a thorough evaluation and examination process of both the physical symptoms and the laboratory tests. Through this process, the doctor will be able to accurately determine if the patient has lupus.
What are the early signs of lupus in females?
The early signs of lupus in females can vary, but the most common symptoms include fatigue, joint pain and stiffness, rashes, mouth sores, hair loss, fever, and swollen glands. Pain, aching, and stiffness in the joints may be one of the earliest signs of lupus, and may also be accompanied by swelling and redness.
Women may experience pain in the small joints of their hands, wrists, and feet. Swelling in the feet and ankles is also common.
A characteristic rash known as the “butterfly rash” often appears across both cheeks, covering the nose and the bridge area. This rash may be red or purple and is typically symmetrical. In some cases, the rash may be itchy or even painful.
Other common symptoms associated with lupus include mouth sores, fever, hair loss, and swollen glands. Women may experience continual fatigue, even after sleeping for nine or more hours. In severe cases, women may experience involuntary rapid weight gain due to fluid retention, shortness of breath, neck stiffness, vision changes, and chest pain.
These symptoms may resemble those of the flu, and an accurate diagnosis of lupus can only be made through blood tests and other examinations.
What is borderline lupus?
Borderline lupus, also known as atypical lupus erythematosus, is an auto-immune disorder that affects the skin, joints, and other organs. It’s a milder version of systemic lupus erythematosus (SLE), meaning it can cause a variety of inflammatory symptoms but it doesn’t typically damage the organs.
Symptoms of borderline lupus include rashes, hyperpigmented spots, photosensitivity, joint and muscle pains, low-grade fever, and fatigue. Unlike systematic lupus erthytematosus, borderline lupus doesn’t cause life-threatening complications and doesn’t require long-term medication to treat.
Treatment for borderline lupus often consists of topical medications, such as corticosteroids, and lifestyle changes, such as a balanced diet and exercise. Additionally, studies have found that stress and genetics can play a role in the development of atypical lupus erythematosus, so it’s important to use stress reducing techniques or practice mindful meditation to try to minimize flare-ups.
What do they look for in a CBC with lupus?
When evaluating a patient with lupus, a complete blood count (CBC) is a routine laboratory test used to assess overall health and aid in diagnosis. During a CBC, a healthcare provider is looking for increases or decreases in certain cell components as indications of possible issues.
A CBC for lupus may include an analysis of several components, including red blood cells, white blood cells, platelets, hemoglobin, hematocrit, and more.
For red blood cells, a CBC will check for changes in size, shape, and number. If there is an abnormality in the red blood cells, it may indicate a condition such as anemia. Anemia in lupus is a sign of inflammation and can lead to symptoms such as fatigue and pale skin.
For white blood cells, a CBC looks for an increased number, which can indicate inflammation and/or infection. White blood cells play a major role in the body’s immune system, and when they become elevated, they can be an indication of lupus.
The platelet count measures the size and number of platelets in circulation, which can assist healthcare providers in determining if there are any irregularities in the blood clotting process, which can often be associated with lupus.
Abnormal platelet counts could be an indicator of a life-threatening complication, such as a stroke or heart attack.
Hemoglobin and hematocrit levels measure the amount of red blood cells in circulation, and can be used to determine if a person is anemic. If the red blood cells are low, it could indicate that the patient is not getting enough oxygen and nutrients to the tissues, which can cause fatigue and other symptoms.
These are just a few of the components a healthcare provider can look at on a CBC with lupus. Depending on the individual patient’s health, a CBC may also look into other components, such as the levels of iron, electrolytes, and vitamins.
A CBC for lupus helps healthcare providers to better understand the patient’s overall health, diagnose any issues and treat them effectively.
Can you have a normal CBC with lupus?
Yes, it is possible to have a normal CBC (complete blood count) test result while living with lupus. However, it is important to keep in mind that a normal CBC result does not always indicate that everything is fine and there is no underlying issue.
Lupus can cause changes in the complete blood count, including anemia, leukopenia, thrombocytopenia, and variation in the white blood cell count. In some cases, the patient may experience no symptoms, making a CBC test an important tool for monitoring lupus.
It is important to make sure to keep your doctor informed of any changes in health that are noticeable and be aware that a normal CBC result does not necessarily mean there are no issues.
