Guide for use: | Record the upper limit of the microalbumin normal reference range for the laboratory. |
---|---|
Collection methods: | Microalbumin is not detected by reagent strips for urinary proteins, and requires immunoassay. 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. 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. |

Implementation in Data Set Specifications: | Diabetes (clinical) DSS Health, Superseded 21/09/2005 DSS specific information: Microalbuminuria is a strong predictor of macrovascular disease and diabetic nephropathy.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 2 of 3 samples collected over a 6-month period in patients in whom other causes of an increased urinary albumin excretion have been excluded. Diagnosis of microalbuminuria is established if 2 of the 3 measurements are abnormal. A small amount of protein (albumin) in the urine (microalbuminuria) is an early sign of kidney damage. If microalbuminuria is present:
If macroalbuminuria is present:
