An electrophoresis interpretive comment is provided with the report.
If reflexed, an immunifixation interpretive comment is provided with the report.
Additional Information
- Urine protein electrophoresis alone is not considered an adequate screening for monoclonal gammopathies
- Immunofixation will not be performed if performed on a previous specimen, unless otherwise specified.
