Collection methods: | Measurement of microalbumin levels should be carried out by laboratories, or practices, which have been accredited to perform these tests by the National Association of Testing Authority. Microalbumin is not detected by reagent strips for urinary proteins, and requires immunoassay. As urinary albumin varies with posture and exercise it is important to collect the urine under very standard conditions; short-term (2 hours) during rest, overnight (approximately 8 hours) or an early morning sample. For screening purposes an early morning urine specimen is adequate, and if the albumin/creatinine ratio is found to be greater than 3.5 mg/mmol then a timed overnight sample should be obtained for estimation of the albumin excretion rate. Test for albuminuria by measuring microalbumin in timed or first morning urine sample. The results considered elevated are

Implementation in Data Set Specifications: | Diabetes (clinical) DSS Health, Superseded 21/09/2005 DSS specific information: A small amount of protein (albumin) in the urine (microalbuminuria) is an early sign of kidney damage. Microalbuminuria is a strong predictor of macrovascular disease and diabetic nephropathy. Incipient diabetic nephropathy can be detected by urine testing for microalbumin. Incipient diabetic nephropathy is suspected when microalbuminuria is detected in two of three samples collected over a six-month period in patients in whom other causes of an increased urinary album excretion have been excluded. Diagnosis of microalbuminuria is established if 2 of the 3 measurements are abnormal. According to the Principles of Care and Guidelines for the Clinical Management of Diabetes Mellitus a test for microalbuminuria is to be performed:
