Diagnosing lupus involves a combination of methods, as no single test can definitively confirm the condition. Here are the key steps and criteria used in the diagnosis process:
Diagnostic Methods:
1. Medical History and Physical Exam:
- Doctors take a thorough history of symptoms, family medical history, and possible exposures to toxins or infections.
- A physical exam is conducted to check for signs and symptoms of lupus.
2. Blood Tests:
- Complete Blood Cell Count (CBC): Checks for low counts of red blood cells, white blood cells, or platelets.
- Antibody Tests: Includes tests for antinuclear antibodies (ANA) and other specific antibodies.
3. Other Tests:
- Urine Analysis: To check for kidney involvement.
- Biopsies: Skin or kidney biopsies may be performed.
- Imaging Tests: Such as echocardiograms to check for heart involvement.
Criteria for Diagnosis:
According to the American College of Rheumatology, at least 4 out of 11 specific criteria need to be met for a lupus diagnosis:
- Mouth sores
- Malar rash (butterfly rash across the face)
- Photosensitivity causing a rash from sun exposure
- Discoid skin rash (round sores or ulcers)
- Serositis (inflammation in the lining of the heart and lungs)
- Joint pain and swelling
- Nervous system and brain problems (e.g., seizures)
- Blood disorders (e.g., anemia)
- Kidney problems
- Positive ANA test result
- Other unusual antibody lab tests
Borderline Lupus:
- If fewer than four criteria are met, a person may be classified as having borderline lupus.
- Individuals with borderline lupus need close monitoring as they may develop full-blown lupus over time.
Symptoms:
- Symptoms can vary widely but often include joint pain, skin rashes, and fatigue.
Regular follow-up, symptom management, and lifestyle adjustments are typically recommended to maintain optimal health and well-being for those with lupus or borderline lupus.
