What's this test for?

This test is ideal if you're on adalimumab (Humira or a biosimilar) for Crohn's disease, ulcerative colitis, or another inflammatory condition and your symptoms are coming back or not improving as expected. It checks whether your body has started making antibodies against the drug, which can cause it to stop working as well. This helps explain why a treatment that used to work may no longer be controlling your symptoms.

What's included in this test?

This test measures two things together: how much adalimumab drug is actually in your blood, and whether your immune system has built antibodies against it. Looking at both numbers together matters because a low drug level alone doesn't tell the full story — pairing it with antibody status helps clarify whether dose changes or a therapy switch makes more sense.

What happens after I get my results?

Your results will show up in your account with the adalimumab drug level and antibody result, along with an explanation of what each value means. If antibodies are detected along with a low drug level, a next step is often switching to a different biologic rather than raising the dose. If antibodies are detected but your drug level is still in the therapeutic range, the report explains that this may not be affecting how well the drug works right now. You can download a standard lab report from your account and track these levels over time using the trends feature if you retest later.

When will I get my results?

Results are typically ready within about 7 days of your blood draw. You'll be notified once your report is available in your account, where you can view the values along with an explanation of what they mean for your treatment.

Who should consider this test?

This test is most useful for people currently taking adalimumab for Crohn's disease, ulcerative colitis, rheumatoid arthritis, psoriasis, or another autoimmune condition who are noticing their symptoms return or not fully improve. It's also worth considering if a treatment that once worked well seems to be losing effectiveness over time. People doing well on adalimumab with no symptom changes typically don't need this test.

What symptoms indicate I may need this test?

If you're on adalimumab and your original symptoms — like abdominal pain, diarrhea, joint pain, or skin flare-ups — start coming back, that's a signal worth checking. Needing more frequent flare treatments or feeling like your usual dose just isn't cutting it anymore are also good reasons to test. Catching antibody formation early can help guide the next treatment decision before symptoms get worse.

How can I naturally support treatment response while on biologic therapy?

While antibody formation itself can't be reversed with lifestyle changes, staying consistent with your dosing schedule helps minimize the chances of your body building antibodies against the drug. Managing overall inflammation through a balanced diet, regular sleep, and stress reduction can support how your body responds to treatment. Avoiding missed or delayed doses is one of the most practical things you can control, since inconsistent dosing is linked to higher antibody development.

What does it mean if my adalimumab antibody result is high?

A high or positive antibody result means your immune system has recognized the adalimumab and started attacking it, which can speed up how quickly your body clears the drug. If this comes with a low drug level, it usually means the drug isn't sticking around long enough to keep working, and a switch to a different biologic is often more effective than increasing the dose. If your drug level is still normal despite antibodies being present, it may not be causing problems yet, but it's worth watching over time.

What causes high adalimumab antibody levels?

Antibodies against adalimumab tend to develop when the immune system treats the drug as a foreign substance, which can happen more often with inconsistent dosing, gaps in treatment, or not using an added immune-suppressing medication alongside the biologic. Some people are simply more prone to building these antibodies than others for reasons that aren't fully understood. Sticking to your prescribed schedule is one of the few controllable factors that can lower the chances of this happening.

How often should I retest my adalimumab antibody levels?

Retesting is generally most useful when your symptoms change or when a dose adjustment is being considered, rather than on a fixed schedule. Some people retest every few months if they're closely monitoring a borderline result. Using the trends feature in your account can help you and track whether antibody levels are rising, falling, or staying steady over time.
