What's this test for?

This test is ideal if you're currently getting allergy shots or drops for cockroach allergies and want to see how your body is responding. It helps if you have been in immunotherapy for a while and want to know whether your immune system is adapting the way it should. It's not a general allergy diagnosis test, but a way to track progress during treatment.

What happens after I get my results?

Your results will show up in your account with the normal range explained so you can see exactly where your IgG4 level falls. If your levels are rising as expected, that's a good sign your immunotherapy is working, and you can keep following your current treatment plan. If levels aren't moving the way you'd hoped, consider discussing timing adjustments to your allergy treatment and retesting in a few months to check progress. You can download a standard lab report anytime and use the trends feature to watch your levels change over time.

What symptoms indicate I may need this test?

This test isn't meant to diagnose new symptoms — it's for people already receiving cockroach allergen immunotherapy. If you're noticing your allergy symptoms like sneezing, itchy eyes, or breathing trouble aren't improving despite treatment, that's a sign to check whether your immune response is building appropriately. Tracking your IgG4 trend can help you understand if your treatment needs adjusting.

How can I naturally support a healthy immune response during immunotherapy?

Getting enough sleep, eating a nutrient-rich diet, and managing stress all help your immune system respond well to allergy treatment. Reducing your exposure to cockroach allergens at home—through regular cleaning and pest control—can also help your treatment work more effectively. Staying consistent with your immunotherapy schedule matters more than any single lifestyle change, since skipped doses can slow your progress.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once ready, they'll be posted directly to your account where you can view and download them.

Who should consider this test?

This test is best for people currently undergoing cockroach allergen immunotherapy who want an objective way to track how their treatment is progressing. It's also useful if you've been in treatment for months and want to confirm your body is building the expected immune response. It's not intended as a first step for diagnosing a cockroach allergy.

What is IgG4 and why does it matter?

IgG4 is a type of antibody your immune system makes in response to repeated exposure to an allergen, like cockroach particles introduced through immunotherapy. Rising IgG4 levels over the course of treatment often signal that your immune system is building a protective, tolerance-like response. Tracking it over time gives you a data point to gauge whether your treatment is moving in the right direction.

What does a high IgG4 level mean?

A higher or rising IgG4 level generally means your immune system is responding well to immunotherapy and building the tolerance that treatment aims for. This is usually viewed as a positive sign that your current treatment plan is working. Keep following your treatment schedule and retest periodically to confirm the trend continues.

How often should I retest?

Many people retest every 6 to 12 months during ongoing immunotherapy to track whether IgG4 levels continue trending upward. Your retest timing may depend on how long you've been in treatment and your specific treatment plan. Using the trends feature in your account makes it easy to compare results over multiple tests.

What should I do if my results are unexpected?

If your IgG4 levels aren't rising the way you expected, it doesn't necessarily mean treatment has failed—responses can vary in speed from person to person. Consider reviewing your consistency with immunotherapy doses and any recent changes in allergen exposure at home. Retesting in a few months can help clarify whether it's a temporary plateau or a longer-term trend worth addressing.
