MICROALBUMINURIA AND ALBUMINURIA
Normally, a very small amount of albumin is excreted in urine. The earliest evidence of glomerular damage in diabetes mellitus is occurrence of microalbuminuria (albuminuria in the range of 30 to 300 mg/24 hours). An albuminuria > 300-mg/24 hour is termed clinical or overt and indicates significant glomerular damage. (See “Proteinuria” under Article “Chemical Examination of Urine”).
