14.7.1 urine protein
Several test strips or dipsticks are commercially available and commonly used to assess proteinuria, but there are several limitations to ther use. Highly alkaline or buffered urines give false positive protein reactions and the test trips are primarily sensitive to changes in albumin and not globulin fractions. Allowances should be made for the urine volume and concentration when interpreting test strip results. Various methods used for assessing plasma protein can be adapted for urinary protein examinations(see earlier section on total protein measurements and chapter7-nephrotoxity
14.7.2 proteins in other body Fluide
The fluide which sometime accumulate in the peritoneum and pleural cavities vary in their protein content. They may be ultrafilteates with low total and particularly high molecular mass protein, or the fluide may contain significant amounts of protein including immunoglobulins, which may reflect malignancy or infection. Simple protein measurements including electrophoresis may provide information on the nature and origin of these fluide.
