Kappa and Lambda Free Light Chains (Bence Jones Protein), Quantitative, Urine
NY State Approved Indicates the status of NY State approval and if the test is orderable for NY State clients.
Qualitative Immunofixation Electrophoresis
Reporting Name A shorter/abbreviated version of the Published Name for a test; an abbreviated test name
Quant Free Kappa/Lambda Light Chains
Specimen Type Describes the specimen type needed for testing
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Two 4 mL aliquots from a well mixed 24-hour urine collection. No preservative. Refrigerate specimen during collection. Send specimen refrigerate in 2 plastic, 6 mL tubes. (MML Supply T465).
Note: 1. Keep refrigerate at all times
2. Total volume and collection time interval required.
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
4 mL (2 vials 2 mL each)
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

Test Information: Total Protein
Total urinary protein is determined nephelometrically
by adding the albumin and Kappa and/or Lambda light
chains. This value may not agree with the total
protein as determined by chemical methods, which
characteristically underestimate urinary light chains.
Test Performed By: ARUP Laboratories
500 Chipeta Way
Salt Lake City, UT 84108
Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.
Monday through Friday
Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.
Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result
Performing Laboratory Location The location of the laboratory that performs the test
CPT Code Information Provides guidance in determining the appropriate Current Procedural Terminology (CPT) code(s) information for each test or profile. The listed CPT codes reflect Mayo Medical Laboratories interpretation of CPT coding requirements. It is the responsibility of each laboratory to determine correct CPT codes to use for billing.
