Test Limitations
Therapeutic concentrations of Ca-dobesilate, levodopa and
phenazopyridine interfere with the assay. Radiopaque media
containing organically bound iodine (e.g. Hexabrix) may cause
false-high results. The administration of gelatin-based plasma
replacements can lead to increased urine protein values. High
homogentisic acid concentrations in urine samples lead to false
results. Hemoglobin from hemolyzed red cells will interfere
with
the assay.
Test Usage
Protein measurements in urine may be used in the
diagnosis and treatment of disease conditions such as renal or
heart diseases, or thyroid disorders, which are characterized
by
proteinuria or albuminuria.
