Interpretation of Serum-free Light Chain Results Kappa (κ) Lambda (λ) κ:λ Ratio Interpretation Key:BM = bone marrow; MG = monoclonal gammopathy; pIg = polyclonal immunoglobulin.

What is a kappa free light chain test?

A kappa free light chain test is a blood test that measures the levels of a certain type of protein in your blood. Your plasma cells (a type of white blood cell that fights infections and illnesses) make light chains. Light chains usually link up with other proteins called heavy chains.

What is the sensitivity of the monoclonal free kappa assay?

Additional information related to the test. This assay is highly sensitive to increasing concentrations of monoclonal free kappa or free lambda light chains in the serum of patients with evolving or relapsing myelomas.

What is Kappa lambda light chains free with ratio?

The normal ranges for free light chains are generally: 3.3 to 19.4 milligrams per liter (mg/L) kappa free light chains. 5.71 to 26.3 mg/L lambda free light chains. 0.26 to 1.65 ratio of kappa/lambda.

What is the ICD-10 code for kappa light chain disease?

ICD-10 code E85. 81 for Light chain (AL) amyloidosis is a medical classification as listed by WHO under the range - Endocrine, nutritional and metabolic diseases .

What does an elevated Kappa Lambda ratio mean?

In general, a low kappa-lambda ratio (< 0.26) indicates the overproduction of lambda light chains, and a high ratio (> 1.65) indicates the overproduction of kappa light chains.

What is diagnosis code n950?

ICD-10-CM Code for Postmenopausal bleeding N95. 0.

What is a free kappa light chain?

There are two types of light chains: lambda and kappa light chains. A free light chains test measures the amount of lambda and kappa free light chains in the blood. If the amount of free light chains is higher or lower than normal, it can mean you have a disorder of the plasma cells.

What is ICD-10 code for elevated serum free light chains?

E85. 81 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM E85.

What is a Kappa Lambda ratio?

Patients with a kappa-lambda FLC ratio less than 0.26 are typically defined as having monoclonal lambda FLC and those with ratios greater than 1.65 are defined as having a monoclonal kappa FLC.

What is light chain ratio?

The test measures the levels of specific types of free light chains, known as kappa and lambda, and also the ratio between the two. Normal test results for free light chains are: 3.3 to 19.4 mg/L kappa free light chains. 5.71 to 26.3 mg/L lambda free light chains. 0.26 to 1.65 ratio of kappa/lambda.

What is the difference between kappa and lambda light chain?

The key difference between kappa and lambda light chains is that the gene encoding the kappa chain is located on chromosome 2, while the gene encoding the lambda chain is located on chromosome 22. Immunoglobulins are composed of light chains and heavy chains. There are two types of light chains in humans.

Clinical Significance

Kappa/Lambda Light Chains, Free with Ratio - The Kappa/Lambda Light Chains, Free with Ratio, Serum test measures the amount of kappa and lambda free light chains (FLCs) in the blood and calculates the kappa to lambda ratio.

Reject Criteria

Gross hemolysis • Grossly lipemic • Microbially contaminated • Heavy visible particulate

Clinical Significance

Kappa/Lambda Light Chains, Free with Ratio, Random Urine - Kappa/Lambda Light Chains, Free with Ratio, Urine by turbidimetry provides a sensitive detection and quantitation of free light chains (FLCs) in urine earlier than electrophoresis and immunofixation.

Test Resources

Please visit our Clinical Education Center to stay informed on any future publications, webinars, or other education opportunities.

Test Includes

κ free light chain quantitation in serum; λ free light chain quantitation in serum; calculated κ:λ light chains ratio in serum

Special Instructions

Values obtained with different assay methods should not be used interchangeably in serial testing. It is recommended that only one assay method be used consistently to monitor each patient's course of therapy. This procedure does not provide serial monitoring; it is intended for one-time use only.

Expected Turnaround Time

Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Collection

Sample should be allowed to clot and the serum separated as soon as possible to prevent hemolysis. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.

Storage Instructions

Refrigerate; samples are stable for 21 days at 2°C to 8°C. For longer storage, freeze at -20°C.

Causes for Rejection

Microbially-contaminated specimen; specimen containing particulate matter; lipemic or hemolyzed specimen

Additional Information

Immunoglobulin molecules consist of two identical heavy chains (α, δ, ε, γ, or μ) that define the immunoglobulin class and two identical light chains (κ or λ). Each light chain is covalently linked to a heavy chain and the two heavy chains are linked covalently at the hinge region.

Overview

A kappa free light chain test is a blood test that measures the levels of a certain type of protein in your blood. Your plasma cells (a type of white blood cell that fights infections and illnesses) make light chains. Light chains usually link up with other proteins called heavy chains.

Test Details

You shouldn’t need to do anything to prepare for a kappa free light chain test. Your healthcare provider will let you know if there are any instructions you should follow before the test. In some cases, you may need to fast (no food or drink for eight hours) or stop taking certain medications before your blood test.

Results and Follow-Up

Your healthcare provider will let you know when you can expect your results from a kappa free light chain test. It may take anywhere from a few days to a week to receive results.

Ordering Recommendation

Recommendations when to order or not order the test. May include related or preferred tests.
