• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Order vs observation: Both
• Method: Detection limit <= 20 mg/L

Key facts

• Microalbumin ug/min [Mass/time] in 24 hour Urine
• Albumin ug/min
• The use of ug/min in the component name is an exception to the usual LOINC rule of ignoring powers of ten differences in reporting units. This is necessary because many laboratories report the per minute excretion rate as well as the per 24 hour exretion rate on the same 24 H sample and do not want ambiguity at the receiving system.
