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.

Special Instructions
Preferred specimen: 1 mL serum and 10 mL random urine in plastic urine container. Alternative: Serum Separator Tube (SST®) and plastic urine container. Transport with refrigeration or cold packs. This panel combines two common tests (serum creatinine and random urine albumin with creatinine), which may also be ordered separately.

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.
