Doctor insights on:
Multiple Myeloma: Kappa and lamda are classifications of light chains of immunoglobulins in humans. They are part of the "y" shaped arms of your antibodies. This ratio is used to distinguish MGUS or monoclonal gammopathy of undetermined significance from multiple myeloma. High ratio favors Multiple Myeloma ...Read more
It also depends on the ratio of kappa to lamda light chains and the presence of polyclonal or monoclonal gammopathy. That is a large amount, while 7mg/l would be normal. Please double check the measurement for grams or milligrams.
If abnormal, it can mean a plasma cell dyscrasia like multiple myeloma, amyloidosis, or Waldenstrom's anemia. Please follow up with the doctor who ordered the test. ...Read more

Go to the website above for good summary of KAPPA and LAMBDA values, and significance;;
Normal levels of serum free light chains are*:
• Kappa: 3.3–19.4 mg/L*
• Lambda: 5.71–26.3 mg/L*
• Kappa/lambda ratio: 0.26–1.65**
*Note: The units here are mg/L; different
laboratories use different units. It is important to
double-check the units used when comparing
numbers in lab values.
**Further Note: In patients with renal impairment,
it is recommended to interpret the results
of the Kappa/Lambda ratio with a modified
reference range of 0.37–3.1. ...Read more
Had abnormal k/ light chain ratio six months ago; now ratio is wnl, but kappa level remains elevated three blood panels later. Thoughts?
I'm not sure I could: Make much of a prognostic distinction between an abnormal kappa/light chain ratio and kappa elevation. Produced within plasma cells, heavy and light chains bind together to form immunoglobulins. Typically producing more light chains than required, the plasma cells enter the blood as free light chains. The activity of myeloma/plasma cell growth is linked to the amount of free light chains in blood. ...Read more
Hello, my Dr. Told me my Kappa light chain is elevated at 26. she told me not to worry and we'll check again in 3 months. What else should I ask /?
Sounds reasonable: You have a minimal degree of change, this may be within the normal range. But a recheck of this test is a good idea just to be sure. It is a rare condition that you do not need to worry about unless you have some symptoms in the future. Do tell us your age as some such conditions primarily occur in older adults ...Read more
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

I have both elevated kappa and Lambda with normal ratio does this mean I have MM. I am scheduled to see a hem/onc, neuro, and rhemy?
Multiple myeloma: Is not an easy disease to have or to diagnose. The findings you mentioned aren't peculiar to the disease, lot of other parameters are needed to diagnose, the most important in this context is the heamatologist/oncologist, together with the other specialists you have appointments with. Can't commit to a diagnosis on this limited platform, wish you wellness ...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.
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.

I had a IgA Heavy Light Chains (HLC), S test done. Ig K/L HLC Ratio, IgA Kappa, S and IgA Lambda, S were in normal range. What does this test mean?
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. 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.

Plasma cell disorder: Monoclonal gammopathy refers to an abnormal production of proteins by cells in the immune system (plasma cells) that are growing out of control. It can be one of the signs of myeloma. A hematologist-oncologist can help. ...Read more
Benign overgrowth: Monoclonal gammopathy of uncertain significance, made of an immunoglobulin g with a kappa light chain. It means nothing. You have a slightly increased chance of getting plasma cell myeloma when you're old. There's nothing you can do about it, so simply resolve not to worry about it. ...Read more
Why do you ask?: If you've been found to have a paraprotein, the real question is, "Do we treat for plasma cell myeloma? " These paraproteins are very common, especially as folks get older; most never progress. The actual level of the paraprotein isn't the key. If this is grams per liter, a value below 10 is "low". If your labs are otherwise good and you feel well, I wouldn't give it another thought. Best wishes. ...Read more
Immune cell problem: Igg-kappa is a type of antibody your body makes to help fight infections, etc. Normally one make lots of different types of igg-kappa. When it is monoclonal, one specific igg-kappa has become very predominant. This can happen in response to an infection, if the immune system is not regulated properly, or in certain malignancies like multiple myeloma. Talk with your doctor for more information. ...Read more
I suspect nothing: As far as this pathologist is concerned, a sed rate of 28 is fine especially for an adult female like yourself. It's worthless unless very high, and even then only to confirm systemic inflammation. The new work on intact and fragmented antibodies shows a huge variability in the ratios of kappa and lambda and I would draw no conclusions whatever. You're a person, not numbers. How do you feel? ...Read more

Can you get all amyloidosis if you have kappa rather than lambda light chains? I also have a kappa lambda ratio of 175
Yes: Listen, Jane. I'm worried about you. You're already on cyclophosphamide and dexamethasone -- extremely potent medications -- yet you list no illness for which they are indicated. It's not for your thyroid cancer. You have a duty to find out exactly what is happening with you, including getting a 2nd opinion from a physician who's explain clearly. Amyloid is confusing; be proactive. ...Read more
Test results came back and say Free Kappa Lt Chains, S 34.81 Free Lambda Lt Chains, s is 29.22Kappa, lambda ratio is 1.19. Is it myeloma What is test 4
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
Indefinitely.: If monoclonal igm gammopathy is fully evaluated and not associated with any malignancy (lymphoma or myeloma) then the diagnosis is mgus (monoclonal gammopathy of undetermined significance). The chances of progression are low, ranging from 0.1% to 1.0%/year. The majority of patients never get cancer. ...Read more
MGUS: Many monoclonal gammopathies can be stable for many years. The only way to know is have the immunofixation and several other tests performed periodically. A referral to the hematologist is appropriate here. ...Read more
In lymphocyte phenotyping of periferial blood, what is the normal percentage for Kappa and Lambda light chains?
0.26-1.65 K/L ratio: Free light chains will normally be present in the blood at low levels, with a kappa/lambda ratio of about 0.26 to 1.65. Increased kappa free light chains and a higher kappa/lambda ratio may mean a plasma cell disorder producing excess monoclonal kappa chains. Increased lambda free light chains and a lower kappa/lambda ratio may mean a plasma cell disorder producing excess monoclonal lambda chains. ...Read more
I have 549igA, 37 sedimentation rate westergren, 21.64 free kappa lt chains, s, and kappa/lambda ratio, s is 1.66 What does this mean?
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, Why were these tests done? Do you have any symptoms? Kappa/lambda ratio is generally a useless test. IgA of 549, per se is not a problem. Sed rate is in the normal range.
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.

My haematologist says my kappa lambda ratio is seriously skewed. Kappa light chains @580 paraproteins 30. Does this imply a poor outcome?
Bad ratio: I am surprised you do not ask your oncologist questions about your outcome. Did you not ask? If you did, did you not get a response that you understood. You oncologist (o) knows your case best of all. Give your o a call and get your answer from the physician who knows you best of all. ...Read more
