What's this test for?

This test is ideal if you're being monitored for a plasma cell disorder or if your recent lab work raised concerns about abnormal protein production. It's often used when there's a suspicion of multiple myeloma, light chain deposition disease, or AL amyloidosis, or to keep an eye on kidney health during treatment for these conditions. Many people take this test as part of ongoing follow-up care rather than as a first-time screening.

What's included in this test?

This test measures the amount of free lambda light chains in your urine, which are small protein fragments that can build up when certain plasma cells grow abnormally. Tracking this single marker over time helps show whether protein production is stable, increasing, or responding to treatment, and it also gives clues about how well your kidneys are filtering these proteins.

What happens after I get my results?

Your results will show up in your account with the normal range clearly explained so you can see exactly where your levels fall. If your Lambda free light chain level is outside the expected range, a simple next step is retesting on a schedule that matches how you've been monitored in the past, since trends matter more than a single number. If a result comes back significantly abnormal or you notice symptoms like swelling, unusual fatigue, or bone pain, seek medical care promptly. You can download a standard lab report anytime and use the trends feature to track your levels over multiple tests.

Who should consider this test?

This test is a good fit for people already diagnosed with or being monitored for a plasma cell disorder such as multiple myeloma or amyloidosis. It's also useful if a previous blood or urine test showed unusual protein patterns that need a closer look. People with unexplained kidney function changes alongside other suspicious symptoms may also benefit from checking this marker.

What symptoms indicate I may need this test?

Bone pain, unexplained fatigue, frequent infections, unusual swelling in the legs or around the eyes, and foamy or bubbly urine can all be signs worth investigating with this test. Unexplained weight loss or persistent low back pain that doesn't improve with rest are also reasons some people get checked. These symptoms don't automatically mean something serious is wrong, but they're worth tracking with a test like this one.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification as soon as your results are posted to your account, so there's no need to call or check in manually. If any values are urgently abnormal, following the safety guidance included with your report is recommended right away.

What does high Lambda free light chain mean?

A high level of lambda free light chains can mean your body is producing extra light chain proteins, which sometimes points to a plasma cell disorder or an issue with how your kidneys are clearing these proteins. It doesn't automatically mean a serious diagnosis, since infections, inflammation, or kidney conditions can also raise this number temporarily. Retesting and looking at the trend over time gives a much clearer picture than one single high result.

What causes abnormal Lambda free light chain levels?

Abnormal levels are most often linked to plasma cell disorders like multiple myeloma, light chain deposition disease, or AL amyloidosis, where certain cells overproduce these light chain proteins. Kidney problems can also cause levels to look abnormal, since the kidneys are responsible for filtering and clearing these proteins from urine. Less commonly, infections or general inflammation in the body can nudge the numbers outside the typical range.

How often should I retest?

If you're actively being monitored for a plasma cell disorder, retesting every few months is common practice to catch changes early. If this is a one-time check based on symptoms and your result comes back normal, you likely won't need to retest unless new symptoms appear. Your care plan and how your levels have trended in the past should guide the exact timing.

What should I do if my results are abnormal?

Start by looking at how far outside the normal range your result falls and whether you've had previous tests to compare it to. Simple next steps include retesting to confirm the result and watching for any new symptoms like swelling, fatigue, or bone pain. If the result is significantly abnormal or paired with concerning symptoms, seek medical care as soon as possible rather than waiting for a routine follow-up.
