The ADA defines abnormalities in albumin excretion as follows:
Category Result (mcg/min)
Normal <20
Microalbuminuria 20-199
Clinical albuminuria ≥200
The ADA recommends that at least two of three specimens collected within a 3-6 month period be abnormal before considering a patient to be within a diagnostic category.
