Programs that offer any of a variety of tests which determine whether an individual shows signs of decline in kidney function at an early enough stage that progression to more severe forms of kidney disease can be delayed or prevented. Included are blood pressure checks; a blood test for creatinine which estimates the glomerular filtration rate (the rate at which waste is being filtered by the kidneys); and a urine test (urinalysis or microalbumin) which looks for unusually large amounts of protein being excreted. Screening is particularly important for people with diabetes, high blood pressure or a family history of kidney disease, as well as for older adults and people of African, Asian, Latin American, or Pacific Island descent.
