Reference Ranges

Category	24h Protein (mg)	24h Protein (g)	Significance
Normal	< 150	< 0.15	Physiological range
Microalbuminuria	30 – 300	0.03 – 0.3	Early renal involvement
Mild Proteinuria	150 – 999	0.15 – 0.99	Monitor renal function
Moderate Proteinuria	1,000 – 3,499	1.0 – 3.49	Further evaluation needed
Severe Proteinuria	3,500 – 9,999	3.5 – 9.99	Significant kidney disease
