Kidney Profile
Also known as: Chronic Kidney Disease, Kidney, CKD
Use
The Kidney Profile combines measurement of serum creatinine (for eGFR estimation) and random urine albumin with creatinine to support early detection, diagnosis, staging, and monitoring of chronic kidney disease (CKD). It reflects kidney function (via creatinine-based eGFR) and kidney damage (via albuminuria) in one orderable panel. eGFR is used as a marker of kidney filtration efficiency and albuminuria indicates kidney damage. This combination aligns with guideline recommendations for CKD care.

Limitations
Creatinine-based eGFR may be affected by factors such as diet, muscle mass, recent vigorous exercise, infection, fever, congestive heart failure, pronounced hyperglycemia, pyuria, or hematuria; elevated urinary albumin may similarly be influenced by exercise or urinary white blood cells or blood.
