What's this test for?

This test is ideal if you're taking adalimumab (Humira) for a rheumatic condition like rheumatoid arthritis and want to know if your medication is working as expected. It helps if you have symptoms that are not improving, or flaring up again, despite being on treatment. Checking your drug level can help explain why the medication may not be controlling your symptoms as well as it should.

What's included in this test?

This test measures the amount of adalimumab drug circulating in your blood at the lowest point before your next dose, known as a trough level. This single measurement matters because it tells you whether you have enough medication in your system to keep inflammation under control, which is essential for managing rheumatic diseases effectively.

What happens after I get my results?

Your adalimumab level will appear in your account along with the target range (typically 5-12 mcg/mL) so you can see exactly where your result falls. If your level is low, next steps often include reviewing your dosing schedule or timing of injections, and possibly retesting after adjustments to see if levels improve. Your standard lab report is downloadable directly from your account, and you can track your levels over time using the trends feature to see how they change with treatment adjustments. If your result is very low and your symptoms are severe or worsening, seek medical care promptly.

When will I get my results?

Results are typically ready within about 7 days of your blood draw. Once processed, they'll be uploaded to your account where you can view your adalimumab level alongside the reference range and a plain-language explanation of what it means.

Who should consider this test?

Anyone currently on adalimumab therapy for a rheumatic condition like rheumatoid arthritis, psoriatic arthritis, or ankylosing spondylitis who is experiencing a loss of symptom control should consider this test. It's especially useful if your symptoms were once well managed but have started to return, or if you're unsure whether your current dose is enough. People with kidney disease or protein-losing conditions that may speed up drug clearance are also good candidates.

What symptoms indicate I may need this test?

Returning joint pain, swelling, stiffness, or fatigue after a period of feeling better on adalimumab can signal it's time to check your drug level. Other signs include needing more frequent flare-ups treated with steroids or other medications, or simply feeling like your current treatment isn't working like it used to. If these symptoms sound familiar, checking your trough level can help identify the cause.

What is adalimumab and why does it matter?

Adalimumab is a biologic medication that blocks a protein in your body called TNF-alpha, which drives inflammation in conditions like rheumatoid arthritis. Having the right amount in your bloodstream is what keeps inflammation—and your symptoms—under control. Too little medication in your system, even if you're taking your doses, means your body may not be getting the anti-inflammatory effect it needs.

What does low adalimumab level mean?

A low level means there isn't enough of the drug in your system to fully control inflammation, which can explain returning symptoms. This can happen if your body is clearing the drug faster than expected, if doses are spaced too far apart, or if your body has formed antibodies against the medication. Discuss dosing frequency and consider anti-drug antibody testing to understand the cause.

What causes low adalimumab levels?

Common causes include not yet reaching a steady drug level early in treatment, a dose that's too low, injections spaced too far apart, or your body clearing the drug faster than usual. Faster clearance can be caused by anti-drug antibodies forming against adalimumab, or by conditions like kidney disease or gut disorders that cause protein loss. Identifying the specific cause usually requires additional testing like anti-drug antibody levels.

How often should I retest?

Retesting is often useful after any change in dose or injection schedule, typically once your levels have had time to reach a new steady state, which can take several weeks. If your levels were low and adjustments were made, retesting helps confirm whether the change worked. Many people also retest whenever symptoms change significantly, whether they improve or return.
