What's this test for?

This test is ideal if you're experiencing symptoms related to kidney function problems, or if you have a condition like HIV, leukemia, or lymphoma that requires ongoing monitoring. It's also useful if you've had exposure to certain heavy metals or toxins that can affect your kidney's small tubes. Many people use this test to keep track of how well their kidneys are filtering and reabsorbing proteins over time.

What's included in this test?

This test measures Beta-2 Microglobulin alongside creatinine in a urine sample, which helps put your B2M value into proper context. Creatinine acts as a reference point since it's produced at a fairly steady rate, so comparing the two gives a more accurate picture of kidney tubule function than measuring B2M alone.

What happens after I get my results?

Your results will show up in your account with the normal range clearly explained next to your value. If your levels are elevated, simple next steps include reducing exposure to any known toxins, staying well hydrated, and retesting in a few months to see if levels return to normal. A downloadable lab report is available in your account anytime, and you can track your results over time using the trends feature to spot patterns early.

Who should consider this test?

People being monitored for HIV progression, certain blood cancers like leukemia or lymphoma, or kidney tubule disorders should consider this test. It's also relevant for anyone with known exposure to cadmium or other substances that can stress the kidneys. If you've had unexplained kidney concerns or are tracking a chronic condition, this test can add useful information.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. Once ready, they'll be posted directly to your secure online account. You'll be able to view, download, and track them right away without needing to wait for a phone call or mailed report.

What symptoms indicate I may need this test?

Symptoms like unusual fatigue, swelling in the legs or around the eyes, changes in urination, or unexplained fevers might prompt this test, especially if you have a known risk factor like HIV or chemical exposure. However, this test is often used for monitoring rather than diagnosing symptoms, so it's commonly ordered even without obvious symptoms. If you have a chronic condition affecting your kidneys or immune system, tracking this marker over time can be more valuable than a single symptom check.

What is Beta-2 Microglobulin and why does it matter?

Beta-2 Microglobulin is a small protein found on the surface of almost every cell in your body. Normally your kidneys filter it out and reabsorb nearly all of it, so only tiny amounts should appear in urine. When more than usual shows up, it can mean the small tubes in your kidneys aren't reabsorbing properly, which can be an early sign of kidney stress or a marker of certain immune-related conditions.

What does high Beta-2 Microglobulin mean?

A higher-than-normal level in your urine usually points to a problem with the kidney's tubules, the tiny structures responsible for reabsorbing this protein. It can also rise with certain exposures like cadmium, or in some immune and blood-related conditions. Staying hydrated, avoiding unnecessary toxin exposure, and retesting are good first steps, and any dramatic or persistent elevation is worth addressing promptly.

What causes high Beta-2 Microglobulin?

Common causes include kidney tubule damage, exposure to heavy metals like cadmium, recent intense exercise, fever, or certain immune system conditions such as HIV progression, leukemia, or lymphoma. Even everyday things like a recent illness or strenuous workout can temporarily raise levels. If your result is high, think about any recent illnesses, exposures, or physical exertion before retesting.

How often should I retest?

If you're monitoring a chronic condition like HIV or a blood cancer, retesting every few months is common to track trends over time. If your first result was elevated due to a temporary cause like exercise or a recent fever, retesting after those factors resolve can give a clearer picture. Your trends dashboard makes it easy to see whether your levels are stable, improving, or climbing over time.
