What does elevated KIM-1 indicate?

Elevated urine KIM-1 specifically indicates proximal tubular cell injury. It rises within 12-48 hours of tubular injury and is highly specific for ATN, distinguishing it from prerenal AKI where KIM-1 is minimal.

How does KIM-1 compare to NGAL for AKI detection?

NGAL rises earlier (2-12h) and is more sensitive. KIM-1 rises later (12-48h) but is more specific for proximal tubular injury. Using both improves AKI classification accuracy.

Can KIM-1 predict CKD progression?

Yes. Urinary KIM-1 predicts CKD progression in diabetic nephropathy and IgA nephropathy. Sustained elevation after AKI identifies patients at high risk for AKI-to-CKD transition.

KIM-1 AKI Progression Biomarker

Use kidney injury molecule-1 (KIM-1) urine concentration to identify proximal tubular injury, predict AKI progression, and differentiate ATN from prerenal AKI.
