ABIM Nephrology case studies

ABIM Nephrology · Put your knowledge to work in context.

The ABIM Nephrology Certification Examination is the American Board of Internal Medicine's assessment for physicians who have completed nephrology fellowship training and wish to be certified in the subspecialty. Candidates are typically internists who have finished an accredited nephrology program and are building a career in consultative nephrology, dialysis, transplantation, or academic practice. The exam samples the full breadth of the field: glomerular and tubulointerstitial disease, acute kidney injury, chronic kidney disease and its progression, fluid, electrolyte and acid-base physiology, hypertension, dialysis and renal replacement therapy, transplantation, stone and cystic disease, inherited kidney disorders, drug-related kidney injury, and perioperative and critical care nephrology. Much of the difficulty comes from integrative reasoning rather than isolated recall - interpreting a urinalysis alongside serologies, choosing the next step in a dialysis prescription, or managing immunosuppression in a transplant recipient with a rising creatinine. The ABIM Nephrology case studies are 5 cases and about 1,638 words.
