1. What is the SLE Criteria Calculator?

The SLE Criteria Calculator helps determine if a patient meets the classification criteria for Systemic Lupus Erythematosus (SLE) based on the sum of points for various clinical and immunological criteria.

2. How Does the Calculator Work?

The calculator uses the SLE classification criteria:

Explanation: The criteria require an ANA titer of ≥1:80 as an entry criterion, and a total score of ≥10 points from various clinical and immunological domains for SLE classification.

3. Importance of SLE Classification

Details: Accurate SLE classification is crucial for diagnosis, treatment planning, and clinical research. The criteria help standardize patient identification across different healthcare settings.

4. Using the Calculator

Tips: Select the appropriate options for each criterion. The calculator will sum the points and determine if the classification criteria are met.

5. Frequently Asked Questions (FAQ)

Q1: What is the minimum ANA requirement?
A: An ANA titer of ≥1:80 is required as an entry criterion for SLE classification.

Q2: What total score is needed for classification?
A: A total score of ≥10 points is required for SLE classification.

Q3: Are all criteria weighted equally?
A: No, different criteria carry different point values based on their clinical significance.

Q4: Can this calculator diagnose SLE?
A: This calculator helps with classification based on established criteria, but final diagnosis should be made by a qualified healthcare professional.

Q5: What if the ANA is negative?
A: A negative ANA (<1:80) means the patient does not meet the entry criterion for SLE classification.
