Test Limitations

Fresh 24 hour urine or first morning catch is preferred to
avoid
possible interferences such as contamination with bacteria,
increase in pH due to breakdown of urea to ammonia or
degradation
of proteins by proteases.

Test Usage

Urine protein electrophoresis may help identify monoclonal
proteins which are excreted into the urine and may elude detection
by serum protein electrophoresis, especially the Bence-Jones
Proteins (monoclonal free kappa or lambda light chains) which are
characteristic of light chain disease.

Offsite Collection Instructions

1. First morning catch is usually the most concentrated and
is
preferred.
2. Collect without additives or preservatives
3. Transport refrigerated (2-8 °C).

UCMC Collection Instructions

1. First morning catch is usually the most concentrated and
is
preferred.
2. Collect without additives or preservatives
3. Transport refrigerated (2-8 °C).

Reference Values

No monoclonal proteins detected.
