The recent Kidney Disease: Improving Global Outcomes (KDIGO) consensus conference proposed a universal nomenclature calling for "Kidney Disease" (KD) to be applied to every form of kidney dysfunction, regardless of etiology. We recognize that the estimated glomerular filtration rate and urine albumin:creatinine ratio are limited in their application to the broad spectrum of KD. However, there are additional in vitro and advanced diagnostic options that can help identify the underlying cause of

While the overarching benefit of generalizing KD as a medical problem lies with screening and detection, the downsides attributable to a nonexact diagnosis (i.e., unclear prognosis and management strategy) are considerable. Finally, the terms "acute kidney injury" and "worsening renal function" are currently used interchangeably by nephrologists and cardiologists alike, and a universal adoption of one term will likely be a sizeable challenge. To be of greater benefit, we propose KD be used as a starting point and that the etiology and other epigenetic determinants of illness continue to be evaluated and characterized.
