Kidney tests

Protein and creatinine tests for kidney

What: Protein in Urine

Why: Traces of a type of protein, albumin in urine (albuminuria) is an early sign of CKD. Persistent amounts of albumin and other proteins in the urine (proteinuria) indicate kidney damage.

Good Score: Less than 30 mg of albumin per gram of urinary creatinine (a normal waste product)

What: Creatinine in Blood (Serum Creatinine)

Why: Healthy kidneys filter creatinine (a waste product from muscle activity) out of the blood. When kidney function is reduced, creatinine levels rise.

Good Score: 0.6 to 1.2 mg per deciliter of blood, depending on other variables
