Monoclonal Protein Study, 24 hour, Urine
Also known as: U-PEP
Use
Aids in the diagnosis and monitoring of monoclonal gammopathies using 24-hour urine specimens. This test involves the measurement of monoclonal proteins in urine, which can help detect and monitor conditions such as multiple myeloma and other related plasma cell dyscrasias.
Special Instructions
Collect 24-hour urine with refrigeration during the collection process. Ensure that the total volume and collection time interval are recorded on the transport tube and test request form.
Limitations
Total urine protein measurement using this method characteristically underestimates urinary light chains. Accurate paraprotein excretion calculation may be challenging in cases where the 24-hour urine collection volume is not properly documented.
