Clinical Significance

Albumin, Random Urine with Creatinine - This test is used to detect albuminuria by measuring albumin and creatine concentrations in a random (spot) urine sample and calculating the albumin-creatinine ratio (ACR). This test is useful for assessing kidney damage, especially at an early stage, and informing management and prognosis of chronic kidney disease (CKD) [1].

Albuminuria, as a marker of kidney damage, provides a more specific and sensitive measurement of glomerular permeability than does proteinuria. An ACR measured from a spot urine sample acquired in the early morning is preferred for initial evaluation of albuminuria. ...
