What's this test for?

This test is ideal if you're taking adalimumab (Humira) for a rheumatic condition like rheumatoid arthritis or psoriatic arthritis and your symptoms aren't improving as expected. It checks whether you have enough of the drug in your blood to work properly and whether your body has started making antibodies against it. This helps explain why a treatment that once worked may have stopped helping.

What happens after I get my results?

Your results will appear in your account with both your adalimumab drug level and antibody status, along with an explanation of what the therapeutic range means. Depending on your results, next steps might include discussing a dose adjustment, a change in dosing interval, or a switch to a different treatment approach. You can download a standard lab report directly from your account at any time, and if you retest in the future, the trends feature lets you track how your drug levels and antibody status change over time.

What symptoms indicate I may need this test?

If your joint pain, stiffness, or swelling has started coming back after your adalimumab treatment had been working well, this test can help figure out why. Other signs include needing more pain relief than usual, flare-ups between doses, or your overall symptoms plateauing instead of continuing to improve. Losing response to a biologic drug over time is common and testing can pinpoint the reason.

How can I naturally support treatment response while on adalimumab?

While drug levels and antibodies are managed through your treatment plan, some lifestyle habits can support overall inflammation control, like eating an anti-inflammatory diet rich in vegetables, fish, and whole grains. Regular gentle exercise, adequate sleep, and stress management can also help reduce overall inflammatory burden. Avoiding smoking is especially important since it's linked to reduced biologic drug effectiveness and increased antibody formation.

When will I get my results?

Results are typically available within about 7 days of your blood draw. This turnaround allows time for the specialized lab testing needed to measure both the drug level and antibody presence accurately. You'll get a notification as soon as your results are ready to view in your account.

Who should consider this test?

Anyone currently on adalimumab therapy for a rheumatic condition who is experiencing a loss of symptom control, or who wants to confirm their dose is working before making any treatment changes, should consider this test. It's also useful for people early in therapy who want to confirm they've reached an effective drug level. This test is a good next step whenever a biologic seems to be underperforming.

What does a low adalimumab level mean?

A low or sub-therapeutic adalimumab level means there isn't enough of the drug in your blood to fully control inflammation. This can happen if your dose or dosing interval needs adjusting, or if your body is clearing the drug faster than expected. If antibodies are also detected, that's often the reason for faster clearance, and a switch in therapy tends to work better than simply raising the dose.

What does it mean if anti-drug antibodies are detected?

Detecting anti-drug antibodies means your immune system has started treating adalimumab as a foreign substance and is working to clear it from your body faster. This can cause your drug level to drop and reduce how well the medication controls your symptoms. If you're still responding well clinically despite antibodies being present, the antibodies may not be significant yet, but they're worth monitoring since they can increase over time.

How often should I retest my adalimumab level?

Retesting is often useful whenever your symptoms change significantly or before making any decision to adjust your dose or switch therapies. Some people retest at set intervals, such as every 6-12 months, to catch antibody development early. Tracking results over time in your account can help you and your care routine spot trends before symptoms worsen.

What should I do if my results are abnormal?

If your adalimumab level is low without antibodies, an increased dose is often considered next. If antibodies are detected alongside low levels, switching to a different biologic tends to be more effective than a dose increase. Adding methotrexate to your regimen is another option that has been shown to help suppress antibody development in some patients.
