Key facts

  • Protein electrophoresis panel in Urine collected for unspecified duration
  • Protein fractions panel
  • This panel contains urine protein electrophoresis fractions, which are used in conjunction with other testing, to find M-bands which can signal monoclonal gammopathies such as multiple myeloma. The urine specimen collections are of an unspecified duration, with random and 24 hour collections being the most common.
