The TRIBE-AKI study examined the relation of urinary neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), interleukin-18 (IL-18), liver-type fatty acid binding protein (L-FABP) and albumin with 3-year mortality after AKI, with uncertain conclusions. The gene discussed is HAVCR1; the disease is acute kidney injury.
