Allergen Specific IgE to Multicolored Asian Ladybeetle (Harmonia axyridis) Biomarker Testing
It measures IgE sensitization to multicolored Asian ladybeetle allergens and helps guide allergy next steps, with easy ordering and Quest-network labs via Vitals Vault.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.

This test looks for allergen-specific IgE antibodies to the multicolored Asian ladybeetle (Harmonia axyridis). A positive result suggests your immune system is sensitized to proteins from this insect.
People most often consider this test when they have allergy symptoms that flare indoors in the fall or winter, especially in homes where ladybeetles cluster, or when symptoms seem “environmental” but common triggers (dust mites, pets, molds) do not fully explain them.
Your result does not diagnose an allergy by itself. It is one piece of evidence that should be matched to your real-world exposures and symptoms with a clinician.
Do I need a Allergen Specific IgE Ladybeetle Multicolored Asian Harmonia Axyridis test?
You may want this test if you get sneezing, runny or stuffy nose, itchy eyes, cough, or wheeze that seems to worsen when ladybeetles are present in your home, attic, window frames, or wall voids. Multicolored Asian ladybeetles commonly “overwinter” indoors, and their body parts and secretions can become airborne and act like indoor allergens.
This test can also be useful if you have ongoing indoor allergy symptoms but your testing for more common indoor triggers is negative or only mildly positive. In that situation, a targeted insect IgE result can help you and your clinician decide whether environmental control (sealing entry points, careful cleanup, HEPA filtration) is likely to help.
You generally do not need this test for a one-time insect encounter without ongoing symptoms. If you have had severe reactions such as trouble breathing, throat tightness, fainting, or widespread hives, you should seek urgent medical care and discuss a full allergy evaluation rather than relying on a single lab value.
This is a laboratory-developed allergen-specific IgE blood test performed in a CLIA-certified lab; results support clinical decision-making but are not a standalone diagnosis.

Get this test with Vitals Vault
Vitals Vault lets you order allergen-specific IgE testing without waiting weeks for an appointment, which can be helpful when you are trying to connect symptoms to a seasonal indoor exposure. After you order, you complete your blood draw at a nearby lab location.
When results are ready, you can use PocketMD to review what “sensitization” means, how to compare your number to your symptom history, and which companion tests often add clarity (for example, total IgE or other indoor allergens). If you are making changes at home, you can also plan a sensible retest timeline with your clinician to see whether exposure reduction is reflected in your overall allergy picture.
If your symptoms are persistent or severe, use your lab result as a starting point for clinician-directed care, not as a reason to self-diagnose or self-treat.
- Order online and complete your draw at a nearby lab location
- PocketMD helps you interpret results in plain language
- Easy reordering if you and your clinician decide to trend results
Key benefits of Allergen Specific IgE Ladybeetle Multicolored Asian Harmonia Axyridis testing
- Helps identify whether ladybeetle exposure is a plausible trigger for your indoor allergy symptoms.
- Distinguishes IgE sensitization from non-allergic irritation when symptoms flare around insects.
- Supports targeted home interventions, such as sealing entry points and safer cleanup strategies.
- Adds context when common indoor allergen tests (dust mite, pet dander, molds) do not match your symptoms.
- Can guide which additional allergen tests to add so you avoid broad, unfocused testing.
- Helps your clinician interpret symptom patterns across seasons, especially fall and winter “indoor” flares.
- Creates a baseline you can reference over time alongside symptom tracking and exposure changes.
What is Allergen Specific IgE Ladybeetle Multicolored Asian Harmonia Axyridis?
Allergen-specific IgE is a blood measurement of IgE antibodies that recognize a particular allergen source. In this case, the allergen source is the multicolored Asian ladybeetle (Harmonia axyridis), an insect that can accumulate in large numbers in and around buildings.
If you are sensitized, your immune system has made IgE antibodies that can bind to ladybeetle proteins. When you are exposed again, that IgE can trigger mast cells and basophils to release histamine and other mediators, which can contribute to symptoms such as sneezing, congestion, itchy eyes, cough, or asthma-like wheeze.
A key detail is that IgE sensitization is not the same as clinical allergy. Some people have detectable IgE but do not get symptoms with real-world exposure, while others have symptoms driven by multiple triggers at once. Your clinician typically interprets this test alongside your history, exam, and sometimes other allergy tests.
Why ladybeetles can act like indoor allergens
When ladybeetles gather indoors, fragments, shed material, and secretions can become part of household dust. Disturbing infested areas, vacuuming without a good filter, or opening walls and window frames can increase airborne exposure.
How this differs from skin testing
Skin prick testing measures an immediate skin reaction to allergen extracts, while this blood test measures circulating IgE antibodies. Blood testing can be useful when skin testing is not available, when you cannot stop certain medications, or when you prefer a blood draw.
What do my Allergen Specific IgE Ladybeetle Multicolored Asian Harmonia Axyridis results mean?
Low or negative ladybeetle-specific IgE
A low or negative result means the test did not detect meaningful IgE sensitization to Harmonia axyridis at the lab’s cutoff. This makes ladybeetle allergy less likely, but it does not fully rule it out, especially if exposure is intermittent or if your symptoms are driven by other indoor allergens. If your symptoms persist, it is often more helpful to broaden the evaluation to other common triggers and to review the timing and setting of your symptoms.
In-range results (lab-reported class or low positive)
Many labs report allergen-specific IgE as a numeric value and sometimes as a “class.” A low positive can indicate sensitization, but it only becomes clinically meaningful when it matches your real-world pattern, such as symptoms that reliably worsen in ladybeetle-infested spaces. If your result is borderline, your clinician may focus on exposure reduction and symptom tracking rather than labeling it as a definitive allergy.
High ladybeetle-specific IgE
A higher value suggests stronger IgE sensitization and increases the likelihood that exposure contributes to symptoms, particularly when you have clear symptom flares during infestations. Even with a high result, the number does not predict how severe your symptoms will be, and it does not by itself diagnose asthma or anaphylaxis. The most useful next step is usually a practical plan: reduce exposure, confirm other co-triggers, and review treatment options with your clinician.
Factors that influence ladybeetle-specific IgE results
Your result can be influenced by overall atopy (a tendency toward allergies), which can raise the chance of multiple positive IgE tests. Cross-reactivity can occur when proteins from different insects share similar structures, so a positive result may sometimes reflect broader insect sensitization rather than a single clear culprit. Timing also matters: if exposure is seasonal, your symptoms may fluctuate even when IgE levels change slowly. Finally, lab methods and reporting cutoffs vary, so it helps to compare results over time using the same lab when possible.

Frequently Asked Questions
What does a ladybeetle (Harmonia axyridis) specific IgE test measure?
It measures IgE antibodies in your blood that recognize proteins from the multicolored Asian ladybeetle. A positive result suggests sensitization, which may or may not match true symptom-triggering allergy.
Do I need to fast before an allergen-specific IgE blood test?
Fasting is usually not required for allergen-specific IgE testing. If you are combining it with other labs (like glucose or lipids), follow the instructions for the full set of tests you ordered.
Can a positive result prove that ladybeetles are causing my symptoms?
Not by itself. A positive result supports the possibility, but diagnosis depends on whether your symptoms reliably occur with exposure and improve when exposure is reduced, along with your clinician’s assessment.
What if my result is negative but I still react when ladybeetles are in my house?
A negative result makes IgE-mediated allergy less likely, but symptoms can still come from other allergens, irritants, or non-IgE mechanisms. Consider evaluating other indoor triggers (dust mites, pets, molds) and reviewing home air quality and infestation control.
How soon should I retest ladybeetle-specific IgE?
IgE levels typically change slowly, so retesting is not usually helpful within weeks. If you and your clinician are tracking trends after major exposure changes, a common approach is to wait several months to a year, and to prioritize symptom tracking over frequent lab repeats.
Is this the same as total IgE?
No. Total IgE measures the overall amount of IgE in your blood, while this test measures IgE directed at one specific allergen source. Many clinicians use both: total IgE for broader context and specific IgE to identify likely triggers.
