Protein Electrophoresis, Serum and Quantitative Free κ and λ Light Chains (FLC) Plus Ratio, Serum

Also known as: Electrophoresis, Serum, FLC, Serum, Free Light Chains, Quantitative, Serum, Kappa Free Light Chains, Quantitative, Serum, Kappa/Lambda Free Light Chains, Quantitative, Serum

Clinical Use

Order Test

Use

Detect and identify monoclonal immunoglobulin gammopathies

Special Instructions

Not provided.

Limitations

Lipemia and hemolysis can cause sample rejection, as well as plasma specimens. The stability of PE is contingent upon proper storage conditions: at room temperature for four days, refrigerated for two weeks, and frozen at -20°C for up to six months. FLC samples must be refrigerated or frozen for extended storage beyond 21 days.

Collection Instructions

Sample should be allowed to clot and the serum separated as soon as possible to prevent hemolysis.

Storage Instructions

PE: Stable when covered at room temperature 25°C for four days; stable refrigerated at 2°C to 8°C for two weeks; stable frozen at -20°C for six months. FLC: Refrigerate; samples are stable for 21 days at 2°C to 8°C. For longer storage, freeze at -20°C.
