Collection methods:Help on this term

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

  • spot urine 30 to 300 mg/L; or
  • timed urine (24 hour collection) 20 to 200 µg/min.
