Please note-To learn more about the symptoms that can be specific to lupus, please refer to our blog; Lupus Symptoms and Signs. There you can find an excellent graphic showing the body and where lupus can present itself along with other helpful information on that topic.
Preparing for a Doctor Visit
- Write down a complete list of symptoms, being as specific as possible.
- Write down any significant life changes or sources of stress.
- Write a list of medications you are taking, and have taken in the past.
- List any diseases or conditions you are suffering from, or have suffered from in the past.
How does a lupus diagnosis get confirmed?
- The patient’s entire medical history
- Signs and symptoms (It is very important to keep detailed records of your symptoms)
- Physical examination findings
- An analysis of the results from routine laboratory tests (see below listing)
- Analysis of specialized tests related to immune status (see below listing)
|Tests for a Lupus Diagnosis|
Some of the laboratory tests may include*:
- Complete Blood Count (CBC): This test will measure the number of red and white blood cells, platelets as well as the amount of hemoglobin (a protein in red blood cells.) Results from this test can indicate anemia, or a low white blood cell or platelet counts which both often occur in conjunction with lupus.
- Chemistry Panel: This is a test to assess kidney function and liver function. Information on blood sugar, electrolytes, and cholesterol and triglyceride levels will also be assessed. Abnormalities could indicate the development of complications from lupus.
- Serum Protein Electrophoresis Test: This is a blood test used to reveal increased gammaglobulin and decreased albumin.
- C-Reactive Protein (CRP): This protein can be a marker of inflammation.
- Complement: Complement proteins are involved in inflammation. These levels are usually low in patients with active disease, especially kidney disease. A low complement is not, in itself, a diagnostic of lupus but must be taken in the context of other clinical findings.
- Erythrocyte Sedimentation Rate: This is a blood test that is used to determine the rate at which red blood cells settle to the bottom of a tube in one hour’s time. If the rate is faster than normal, it may be an indication of a systemic disease, like lupus. It is important to note that this sedimentation rate, or rate of settling, does not specifically indicate lupus, but can be elevated if other inflammatory conditions are present like cancer or an infection.
- Kidney and Liver Assessment: Because lupus can affect these organs, blood tests will be done to see how well they are functioning.
- Urinalysis: An increased protein level or red blood cells in the urine can occur in lupus if it has affected your kidneys, therefore an examination of a sample of your urine will be performed. A measurement will be taken to determine how effective the kidneys are at filtering the blood to eliminate waste.
- Antinuclear Antibody Test (ANA): A positive ANA test for the presence of these antibodies, which are produced by your immune system, indicates a stimulated immune system. While most people with lupus have a positive ANA test, most people with a positive ANA test do not have lupus. If you have a positive ANA test, more specific antibody testing will most likely be advised.
- Anitphospholipid Antibodies (APLs): Phospholipids are antibodies that are present in approximately one out of every two people with lupus. A positive test can help confirm diagnosis as well as help identify women with lupus who have certain risks (like blood clots and miscarriage) that would require preventative treatment and monitoring. Note that the presence of phospholipids also occurs in people without lupus and therefore, there presence alone is not enough for a lupus diagnosis.
- Anti-dsDNA test:This is the protein directed against the double-stranded DNA, the material making up the genetic code. This test is very specific for lupus, and can be used to determine a lupus diagnosis. One in every two people with lupus has a positive anti-dsDNA test. The presence of this anti-dsDNA can indicate a higher risk of lupus nephritis, kidney inflammation that can occur with lupus. This test can confirm the need to closely monitor the kidneys. Only half the people with lupus have a positive test, so a positive or negative test does not mean you have lupus.

- Chest X-Ray: Abnormal shadows in a chest x-ray may be an indication of fluid or inflammation in your lungs.
- Echocardiogram: Sound waves used in this test produce images of your beating heart in real time. It can suggest problems with valves and other parts of your heart.
