Diagnostic Criteria for Systemic Lupus Erythematosus

The diagnostic criteria for systemic lupus erythematosus (SLE) involve assessing symptoms and laboratory test results. Doctors look for signs such as fatigue, joint pain, skin rashes, and fever, along with specific blood findings like antibodies. A combination of these factors helps confirm the diagnosis. Typically, if a person has four or more of these features from various categories—such as skin, joints, kidney, or blood issues—they are diagnosed with SLE. These criteria guide healthcare providers in accurately identifying the disease to ensure appropriate treatment and management.
