Editing Albuminuria (section)

==Diagnosis/Testing==
According to Kidney Disease Improving Global Outcomes (KDIGO) guidelines, albuminuria is categorized into 3 grades with increasing severity of associated kidney injury: A1, A2, and A3. This grading scale, along with [[Glomerular filtration rate|estimated glomerular filtration rate]], is used to assess risk of progression and severity of kidney disease, particularly in [[chronic kidney disease]].<ref name="Eknoyan_2013" />
