Testing for CKD

Testing for CKD

If you or a loved one belongs to a high-risk group, ask your primary-care physician about these tests and be especially insistent about the last one. Your doctor may want to perform other tests as well. 

4 Simple, Life-Saving Tests:

What:  Blood Pressure
Why:  High blood pressure can damage small blood vessels (glomeruli) in the kidneys.
Good Score:  Below 140/90 is good for most people.  Below 130/80 is better if you have chronic kidney disease.  Below 120/80 is best.

What:  Protein in Urine
Why:  Traces of a type of protein, albumin in urine (albuminuria) are 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.

What:  Glomerular Filtration Rate (GFR)
Why:  This is the most sensitive and accurate gauge of kidney function.  Doctors measure blood creatinine levels and perform a calculation based on age, race, and gender.
Good Score:  Over 90 is good.  60-89 should be monitored.  Less than 60 for 3 months indicates CKD.
