Lupus is short for systemic lupus erythematosus (SLE) that is an autoimmune disorder. Because its symptoms can confuse doctors and patients, it is quite necessary to choose correct tests for diagnosing Lupus disease.

- Anemia and decline of white blood cell count
- Nausea, vomiting, diarrhea, enlarged liver, etc.
To determine whether you have Lupus disease, some lab tests are needed.
Firstly, you need to take blood and urine tests. Complete blood count, erythrocyte sedimentation rate, kidney and liver assessment, ANA tests, etc, are commonly seen in patients’ test reports. On one hand, they can help detect Lupus. On the other hand, they can help determine whether Lupus has affected your kidneys or liver.
Secondly, imaging tests may be taken. If the doctor suspects Lupus is attacking your heart or lung, you should do chest X-ray and echocardiogram. A image of chest can reflect fluid retention or inflammation in the lungs, while echocardiogram can check out heart problems.
