Albumin, Random Urine with Creatinine - This test checks for albuminuria by measuring albumin and creatinine levels in a random urine sample and calculating the albumin-creatinine ratio (ACR). It's key for spotting early kidney damage and guiding the treatment and outlook of chronic kidney disease (CKD). Albuminuria is a more precise indicator of kidney health than general protein levels in urine, making this test crucial for early detection and management of CKD.
