General Information

Protein measurements in urine are used in the diagnosis and treatment of renal and heart disease which are characterised by proteinuria or albuminuria. Proteinuria is usually first detected by a positive reaction for protein using a urine dip-stick. A ‘trace’ protein corresponds to a protein concentration of approximately 0.3 g/L and will prompt confirmation before further investigation. Proteinuria in excess of 2g/24h is virtually always pathological and usually signifies glomerular disease.

Patient Preparation

None

Notes
