Light chains: Light chains (kappa and lambda) are a part of the immunoglobulin molecues the body makes. A given plasma cell only makes one type of light chain, most commonly this is kappa. When immunoglobulin cells proliferate like a neoplasm, then one type will overwhelm the others. Your values are nearly even, and the ratio is not abnormal, so it is unlikely that you have myeloma or another Ig-producing lesion. ...Read more

Kappa Lambda ratio u 1.92(L) Free kappa LT chains ur 32.10 (H) Free Lambda LT chains ur 16.70 (H) 24 hour urine What does this mean?

Kappa Lambda ratio u 1.92(L) Free kappa LT chains ur 32.10 (H) Free Lambda LT chains ur 16.70 (H)  24 hour urine  What does this mean?

Nothing: In isolation, these mean nothing at all. If only one of the chains is being excreted, I'd worry about plasma cell myeloma. If you're leaking protein in your urine because of your diabetes, this is more concerning than light chain ratios. ...Read more

Question about lab results from hematologist. Free kappa light chains serum 19.97 (range is 3.30-19.40mg/l) Normal lambda and ratio.

Question about lab results from hematologist. 

Free kappa light chains serum 19.97 (range is 3.30-19.40mg/l)

Normal lambda and ratio.

What for?: What are you being tested for? All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, Serum free light chain assay and kappa/lambda ratio are unreliable tests. Better would be have serum and urine protein electrophoresis. ...Read more

Serum free light chain test shows normal kappa (8.7mg/dl), low lambda (3.80), high kap/lam ratio (2.31). Serum $ urine electrophoresis show no monoclonal protein, nor does serum immunofixation. Likely MGUS, myeloma, or admyloidosis? CBC/met panel ok.

Serum free light chain test shows normal kappa (8.7mg/dl), low lambda (3.80), high kap/lam ratio (2.31). Serum $ urine electrophoresis show no monoclonal protein, nor does serum immunofixation. Likely MGUS, myeloma, or admyloidosis? CBC/met panel ok.

False positive rate: There is 30% or so false positive rate of kappa/lambda ratio in people without MGUS, myeloma or other disorders. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more

Causes if a polyclonal gammopayhy with elevated kappa and lambda free light chains? Seems to be of the IGG type slightly elevated count.

Causes if a polyclonal gammopayhy with elevated kappa and lambda free light chains? Seems to be of the IGG type slightly elevated count.

Polyclonal IgG: It can be caused by numerous inflammatory, infectious, and malignant causes, for example; TB, Rheumatoid arthritis, cirrhosis of the liver, lymphoma, and MS. A more extensive list, click on Table 3 link inside article below. http://www.aafp.org/afp/2005/0101/p105.html http://www.ncbi.nlm.nih.gov/pmc/articles/PMC356447/ Mild elevation could simply be a mild cold with a rhinovirus. No worries. ...Read more

What is the significance of having low serum levels of kappa and lambda free light chains? I had high ch50 and normal C3 and c4.

What is the significance of having low serum levels of kappa and lambda free light chains?  I had high ch50 and normal C3 and c4.

The: Concern would be low ch50 and low c3 ; c4, like in lupus. Elevations in kappa or lambda would be of concern for myeloma, not to worry about these levels. ...Read more

Nothing: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, The tests you mentioned have a high number of false positives and false negatives and are or questionable value. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats.

How much increase in kappa lambda ratio Wud mean worrisome?

How much increase in kappa lambda ratio Wud mean worrisome?

Kappa/lambda: Hi, the normal Kappa/lambda is approximately 0.26 to 1.65. this ratio has to be interpreted along with Serum electrophoresis and also the free light chain values (kappa and lambda), if the free chain is elevated and the ratio is elevated then that could be due to plasma cell disorders like multiple Myeloma or Primary Amyloidosis if the symptoms present. Having said that it's not easy to draw ...Read more
