Albumin / Creatinine Ratio, Random Urine
Albumin (also known as microalbumin) is the measurement of albumin (a protein) in urine at concentrations below the sensitivity of dipstick testing for total protein performed in a routine urinalysis. Albuminuria is an important indicator of deteriorating renal function.
The value of testing albumin levels is well established in people with diabetes1 because over time, high glucose levels damage small vessels in the kidneys. Twenty percent to 40% of type II diabetics with sustained albuminuria will progress to overt kidney disease.
The American Diabetes Association (ADA) recommends that routine urinalysis be performed annually on adults with diabetes.1 If the urinalysis is negative for protein, albumin measurement is recommended, in order to catch kidney disease at an earlier stage.
Fasting is not required. Physical exercise during the previous 24 hours can cause a transient elevation in albumin. Other variables, including infection, fever, congestive heart failure, and marked hypertension, can also result in increased albumin levels.
