Please note, this test is for timed urine albumin testing. If you wish to request this test on a spot/random urine specimen, please see: Microalbumin - Spot/Random Urine.

A creatinine excretion test is performed on 24 hour urine collections in order to confirm the adequacy of the collection. This will also enable the Albumin / Creatinine ratio to be calculated and thus provide a more meaningful result.

In timed urine collections other than 24 hours, (+/- 2 hours), the 24 hour excretion cannot be calculated due to different day time and night time excretion patterns of various analytes.

Specimen may be a 12 hour overnight urine in a PLAIN bottle. Please note the time and date of the start and of the end of collection.

This test cannot be added after 72 hours of collection.
