Protein, Total, Urine

Also known as: UTP

Clinical Use

Use

The Protein, Total, Urine test is designed to measure the protein concentrations in urine over a specified collection period. It is useful for diagnosing and monitoring kidney conditions, such as glomerulonephritis and preeclampsia, by evaluating renal function through protein loss in urine.

Special Instructions

Not provided.

Limitations

The quantitative spectrophotometry method used in this test can underestimate urinary light chains, which may affect result interpretation in cases of significant proteinuria or monoclonal gammopathy.
