Acute Interstitial Nephritis Risk Calculator
Estimates likelihood of AIN in at-risk patients using clinical features, exposure history, and urine/lab findings.
Clinical note: This tool is for educational and decision-support use only.
It is not a validated diagnostic rule and must not replace clinician judgment, nephrology review,
medication reconciliation, or kidney biopsy when clinically indicated.
Scoring approach: points are assigned based on common clinical features associated with AIN. This is a practical screening aid, not a validated prediction model. Urine eosinophils are included with low weight because they are not sufficiently reliable alone for diagnosis.
