InstalabIgE Inhalants
Should you take a IgE Inhalants test?
This test is most useful if any of these apply to you.
46 Biomarkers Included
- Ribwort IgEEnglish plantain, a weed pollen present through much of the warm season.A positive can explain prolonged spring-to-fall weed symptoms.
- Total IgEMeasures the overall level of allergy antibody in your blood, giving a backdrop for how allergic your body is in general.A high level supports an allergic picture but names no trigger; a normal level does not rule allergy out.
- Dust Mite (D. Farinae) IgETargets the other major house dust mite; it usually reacts alongside the first because the two mites share many proteins.Confirms dust mite as a genuine trigger, especially when both mite species test strongly positive.
- Dust Mite (D. Pteronyssinus) IgEMeasures allergy antibodies (called IgE) against the most common house dust mite, a leading year-round driver of nasal and asthma symptoms.A strong positive is one of the most consistent predictors of asthma and persistent rhinitis in this panel.
- Nettle IgEA weed pollen common near disturbed ground and often overlapping with the pellitory family.Usually part of a broader weed-pollen sensitivity.
- Russian Thistle IgEA tumbleweed pollen important in dry western regions.A positive points to late-summer weed exposure in arid areas.
- Ryegrass IgEA widespread lawn and pasture grass whose pollen cross-reacts strongly with other temperate grasses.Positive results usually reflect the same grass-pollen allergy as Timothy.
- Timothy Grass IgEA major temperate grass pollen and common cause of summer hay fever; it shares proteins with several other grasses here.A strong positive often signals genuine grass allergy driving late-spring and summer symptoms.
- Bahia Grass IgEA subtropical lawn grass common in the southern United States.A positive suggests warm-climate grass exposure driving symptoms.
- Johnson Grass IgEA tall warm-season grass whose pollen can extend the grass season into summer.Adds to the grass-pollen picture and often overlaps with other grasses.
- Kentucky Blue/June GrassA common temperate lawn grass that cross-reacts with other northern grasses.Usually part of a broader temperate grass sensitivity.
- Redtop GrassA temperate bentgrass found in fields and lawns.Adds detail to the temperate grass group and is rarely a lone trigger.
- Bermuda Grass IgEA warm-climate grass pollen common in southern regions; it cross-reacts less with temperate grasses.A positive can reflect a separate warm-season trigger, not just overlap with other grasses.
- Cockroach IgEDetects sensitization to cockroach allergen, an important indoor trigger of asthma, especially in urban homes.A positive points to an indoor, year-round exposure worth reducing at home.
- Australian PineA tree pollen relevant in subtropical coastal areas such as Florida.A positive suggests regional exposure in warm coastal climates.
- Mountain Cedar Tree IgEA winter-flowering tree pollen known for intense seasonal symptoms in the south-central United States.A positive points to unusual winter or early-year allergy symptoms.
- Pecan TreeA spring tree pollen common in the south-central United States, distinct from pecan food allergy.A positive reflects inhaled pollen exposure, not a nut food allergy.
- Cat Dander IgEMeasures reaction to cat allergen, an indoor trigger carried on skin flakes that lingers in homes long after a cat leaves.In teens, cat sensitization was linked to roughly 3.6 times higher odds of current asthma.
- Dog Dander IgEMeasures reaction to dog allergen, another persistent indoor trigger.In teens, dog sensitization carried about 4.8 times higher odds of current asthma.
- Orchard GrassA widespread pasture and hay grass in temperate regions.Typically tracks with other temperate grasses like Timothy and ryegrass.
- Sweet Vernal GrassAn early-flowering temperate grass that can open the grass season.A positive can explain earlier-than-expected spring grass symptoms.
- White MulberryA tree pollen that can cause heavy spring symptoms in warm urban areas.A positive adds to spring tree-pollen sensitivity.
- DandelionA widespread weed whose pollen can trigger symptoms in spring and summer.A positive adds to the weed-pollen picture but is rarely the sole trigger.
- Lambs Quarters Weed IgEA common weed pollen active in summer and early fall.A positive adds to late-season weed sensitivity alongside ragweed.
- Rough Pigweed IgEA widespread amaranth weed whose pollen peaks in late summer.Often positive together with lambs quarters because of shared proteins.
- Western Ragweed IgEA regional ragweed species that closely overlaps with common ragweed.Usually reflects the same fall ragweed allergy rather than a distinct trigger.
- EucalyptusA tree pollen found where eucalyptus is planted in warm regions.A positive reflects local exposure and adds to the tree-pollen picture.
- CockleburA late-summer weed related to ragweed with overlapping pollen proteins.Tends to track with ragweed sensitivity in the fall.
- Common RagweedThe classic late-summer and fall weed pollen and a leading cause of autumn hay fever.A strong positive points to fall symptoms and is a common target for allergy treatment.
- Cottonwood IgEA poplar tree pollen released in spring that shares proteins with willow and aspen.A positive contributes to the spring tree-pollen picture.
- Cultivated Oat Grass IgEA cereal grass pollen relevant in agricultural areas.Positive results usually reflect the broader grass-pollen allergy.
- Elm Tree IgEA spring, and sometimes fall, tree pollen found across temperate regions.A positive points to tree-pollen symptoms in spring.
- Giant RagweedA tall ragweed whose pollen cross-reacts with other ragweeds.Tends to track with common ragweed; together they define fall pollen sensitivity.
- Maple Tree IgEAn early-spring tree pollen produced by maple and box elder species.A positive can explain very early spring outdoor symptoms.
- Mesquite TreeA tree pollen important in the arid southwestern United States.A positive points to regional tree exposure in dry climates.
- Dust Mite (D. microceras) IgEDetects a sibling species of D. farinae that overlaps heavily with the two main house dust mites.Usually tracks with the other mites and rarely changes the overall picture on its own.
- Mold (Generic) IgEScreens for reaction to common mold, a trigger tied to damp spaces and to more severe asthma symptoms.Fungal sensitization has been linked to more wheezing and flare-ups; a positive warrants checking for damp indoor areas.
- Oak Tree IgE A common spring tree pollen produced in large amounts across many regions.A positive points to early to mid-spring outdoor symptoms.
- Olive Tree IgEA spring tree pollen important in Mediterranean and warm dry climates; it overlaps with ash.Relevant mainly where olive or related trees grow; a positive explains spring symptoms there.
- Rough Marsh ElderA ragweed-family weed that flowers in late summer and fall.Usually reflects the same fall weed allergy as ragweed.
- Scale IgESaltbush or scale, a weed pollen of dry and coastal regions.A positive suggests regional weed exposure in arid or coastal areas.
- Walnut Tree Pollen IgEAirborne pollen from walnut trees, a spring trigger distinct from walnut food allergy.A positive reflects inhaled spring exposure, not a food reaction to walnuts.
- Alder TreeA very early tree pollen that cross-reacts strongly with birch.Often positive alongside birch, marking late-winter to early-spring symptoms.
- Birch Tree IgEA major spring tree pollen whose main protein cross-reacts with certain raw fruits and nuts.A positive can explain early-spring symptoms and sometimes mouth itching from apples or stone fruit.
- BromegrassA common field and roadside grass in temperate regions.Generally part of a wider grass sensitivity rather than a standalone cause.
- Canary GrassA grass found in wetlands and cultivated areas.Typically overlaps with other temperate grass pollens.
About IgE Inhalants
If your nose runs every spring, your eyes itch around the cat, or your chest tightens in a dusty room, your immune system may be reacting to something in the air. This panel measures the allergy antibodies your body makes against the specific things you breathe in.
Instead of guessing whether it is the dog, the pollen, or the dust, this panel checks your reaction to dozens of common airborne triggers from a single blood draw. It turns a vague sense of having allergies into a specific map of what your body responds to.
What This Panel Reveals
Your body makes a type of antibody called immunoglobulin E (IgE) when it treats a harmless substance as a threat. Each test here measures IgE aimed at one trigger, so a positive result means your immune system has learned to recognize that trigger. The Total IgE test measures the overall amount of this antibody, giving a backdrop for how allergic your body is in general.
One group of tests covers the triggers you live with year round: three closely related dust mite species, cat and dog dander, cockroach, and mold. These are the usual drivers of symptoms that never seem to follow a season.
A second, larger group covers pollens that come and go with the calendar: many grasses such as Timothy and Bermuda, trees such as birch, oak, and cedar, and weeds such as ragweed and pigweed. Which ones light up often points to which months will be hardest for you.
Read together, the panel shows not just whether you are allergic, but how broadly. Recognizing many triggers, called polysensitization, matters: in one study of adolescents and adults, people with both asthma and hay fever recognized a median of 7 airborne allergen molecules, compared with 1 to 3 in those with only one of the two conditions.
How to Read Your Results Together
The value of this panel is in the shape of the whole result, not any single line. A few patterns are worth learning to recognize on your own report.
| Pattern | What It Suggests |
|---|---|
| Dust mite, pet, cockroach, or mold positive; pollens quiet | Indoor, year-round triggers. Symptoms likely tied to home and bedroom, not the calendar. |
| Several pollens positive in one category; indoor markers quiet | Seasonal allergy. The mix of grass, tree, or weed positives predicts your worst months. |
| Many positives across all categories plus high Total IgE | A highly allergic, polysensitized profile, which carries a higher chance of asthma alongside hay fever. |
| One strongly positive dust mite, little else | A focused, dose-dependent trigger where the antibody level itself matters. |
Level matters, not just positive versus negative. Children strongly sensitized to dust mite (antibody level at or above 3.5 units per liter) had the highest risk of asthma and hay fever in a birth cohort, and among people with hay fever, each step up in dust mite antibody was linked to roughly 40 percent higher odds of going on to develop asthma. In sensitized teens, dust mite carried about 3 times the odds of current asthma, cat about 3.6 times, and dog about 4.8 times.
When Results Can Be Misleading
A positive result means your immune system recognizes a trigger, not that it will always make you sick. Many people without symptoms have positive results, so a positive only counts clinically when it matches something you actually notice in daily life.
Related plants share similar proteins, so an allergy to one grass or one ragweed can make several others in the panel turn positive even when only one is the true culprit. A long list of positives can overstate how many separate allergies you have. Sorting genuine triggers from look-alikes changed the recommended allergy-shot targets in at least half of cases in one review, which is why standardized interpretation of a broad panel is still evolving.
A very high Total IgE can also nudge individual results upward and produce nonspecific positives, so results in highly allergic people deserve extra caution and a clinician's read.
What to Do with Your Results
Start by circling the positives that line up with your symptoms by season and setting. Those are the ones worth acting on, whether through targeted avoidance, medication timing, or a conversation about allergy shots. Because blood testing and skin testing each catch some sensitized people the other misses (on average around one in four, though this varies considerably from one allergen to another), an allergist may add a skin test when a result and your history disagree.
If mold or a fungal trigger is positive, it is worth checking for damp indoor spaces, since fungal sensitization has been tied to more wheezing and asthma flare-ups. If many pollens are positive and you are considering allergy shots, component-level testing can separate genuine triggers from cross-reacting look-alikes before you commit.
Airborne allergy antibody levels tend to change slowly, over years rather than weeks, so annual retesting is a reasonable rhythm if you are actively managing symptoms, though no formal guideline sets a fixed interval. Retest sooner when you develop new symptoms, move to a new region, or start or finish allergy shots, and compare draws to see whether a trigger is fading or a new one has emerged.
