What's this test for?

This test is ideal if you're experiencing persistent asthma symptoms, chronic allergic reactions, or unexplained respiratory issues that aren't responding well to treatment. It helps measure inflammation caused by eosinophils, a type of white blood cell that becomes active during allergic reactions and asthma flare-ups. Many people use this test to monitor how well their asthma or allergy treatments are working or to understand the severity of their eosinophil-related inflammation.

How should I prepare for this test?

No special preparation is typically required for this test. You don't need to fast or make any changes to your medications before testing. However, it's helpful to inform your healthcare provider about any asthma or allergy medications you're currently taking, as they may want to interpret your results in that context. Continue taking all prescribed medications unless specifically instructed otherwise by your doctor.

What's included in this test?

This test measures Eosinophil Cationic Protein (ECP), which is a marker of eosinophil activity and inflammation in your body. Eosinophils are white blood cells that become activated during allergic reactions, asthma attacks, and other inflammatory conditions, releasing ECP into your bloodstream. Elevated ECP levels can help explain persistent respiratory symptoms, assess asthma severity, and guide treatment decisions for allergic and inflammatory conditions.

What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your ECP levels mean for your allergy and asthma management. These notes include personalized recommendations like adjustments to your current treatment plan, lifestyle modifications to reduce exposure to allergens, or whether you should follow up with an allergist or pulmonologist. You'll also get the standard lab report and can track your ECP levels over time using our trends feature to see how your interventions are affecting inflammation.
When will I get my results?
Your test results are typically available within 3-5 business days after your sample reaches the laboratory. You'll receive an email notification as soon as your results are ready to view in your secure online account. More complex analysis may occasionally take a bit longer, but most ECP tests are processed quickly to help guide your treatment decisions.
Who should consider getting this test?
This test is especially valuable for people with persistent or severe asthma that's difficult to control with standard treatments. It's also useful for individuals with chronic allergic conditions, unexplained eosinophilia found on a blood count, or those who need to monitor the effectiveness of asthma or allergy medications. If you're experiencing frequent asthma flare-ups or your allergist wants to assess your level of allergic inflammation, this test can provide important insights.
What symptoms indicate I may need this test?
You may benefit from this test if you're experiencing frequent wheezing, shortness of breath, chest tightness, or persistent coughing that doesn't improve with standard asthma medications. Other indicators include chronic nasal congestion, recurring sinus infections, skin reactions like eczema or hives, or if you've been told you have elevated eosinophils on a routine blood test. This test helps determine if eosinophil-driven inflammation is contributing to your symptoms.
How can I naturally support reduced eosinophil inflammation?
Reducing exposure to common allergens like dust mites, pet dander, pollen, and mold can help minimize eosinophil activation. Using HEPA air filters in your home, washing bedding in hot water weekly, and keeping indoor humidity below 50% can make a significant difference. Anti-inflammatory foods rich in omega-3 fatty acids (like salmon, walnuts, and flaxseeds) and antioxidants (berries, leafy greens) may help modulate your immune response and reduce overall inflammation.
What is Eosinophil Cationic Protein and why does it matter?
Eosinophil Cationic Protein (ECP) is a substance released by eosinophils, a type of white blood cell that plays a key role in allergic reactions and asthma. When eosinophils are activated by allergens or inflammatory triggers, they release ECP, which causes tissue damage and inflammation in the airways and other affected areas. Measuring ECP levels helps doctors understand how active your allergic or asthmatic inflammation is and whether your current treatment is effectively controlling it.
What does high ECP mean?
Elevated ECP levels indicate active eosinophil inflammation, which often means your asthma or allergies are not fully controlled. High ECP can suggest that your airways are inflamed and irritated, making you more susceptible to asthma attacks, breathing difficulties, and allergic reactions. This information helps your doctor determine if you need stronger medications, adjustments to your current treatment plan, or additional strategies to manage your condition more effectively.
How often should I retest my ECP levels?
If you're monitoring asthma control or allergy treatment effectiveness, your doctor may recommend retesting every 3-6 months or after making changes to your medication regimen. During periods of stable symptoms with well-controlled asthma, annual testing may be sufficient. If you experience a flare-up or worsening symptoms, your doctor might order more frequent testing to assess inflammation levels and guide treatment adjustments. The timing depends on your individual condition and treatment goals.

What this means

Your ECP level is elevated, indicating active eosinophil inflammation in your body. This suggests your asthma or allergies may not be fully controlled and your airways are experiencing ongoing inflammation. Elevated ECP levels can help explain persistent respiratory symptoms and guide your doctor in optimizing your treatment plan.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
