Laboratory standard—upper limit of normal range for microalbumin, total milligrams per litre N[NN].N
Identifying and definitional attributes
Metadata item type:
Data Element
Short name:
Microalbumin level—upper limit of normal range (milligrams per litre)
METeOR identifier:
270334
Registration status:
Health, Standard 01/03/2005
Definition:
The laboratory standard for the value of microalbumin measured in milligrams per litre (mg/L), that is the upper boundary of the normal reference range.
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.
