Overview of the Alternaria alternata IgE Level
The Alternaria alternata IgE Level blood test measures allergen-specific Immunoglobulin E (IgE) antibodies directed against Alternaria alternata, a common mould whose airborne spores can trigger allergic symptoms in sensitised individuals.
Alternaria is found widely in the outdoor environment, particularly on plants, soil and decaying organic material, although spores can also enter buildings and may be present in damp indoor environments. Exposure varies according to weather, season, geography and environmental conditions.
The test contains 1 biomarker: Alternaria alternata IgE level. It may provide useful information where symptoms such as recurrent sneezing, nasal congestion, itchy or watery eyes, cough or wheezing appear to coincide with mould exposure.
A detectable specific IgE result indicates that the immune system has become sensitised to Alternaria alternata. Sensitisation is not the same as clinical allergy. Some people have detectable allergen-specific IgE but experience few or no symptoms when exposed.
Conversely, a negative Alternaria-specific IgE result does not explain every symptom associated with damp or mouldy environments. Mould exposure can also cause irritation through mechanisms that are not IgE-mediated, and other mould species, house dust mites, pollens or animal allergens may be responsible.
Results are therefore most useful when interpreted alongside the timing and location of symptoms, exposure history, asthma or eczema history and any other allergy testing.
What Does the Alternaria alternata IgE Level Test Check?
This test measures 1 biomarker.
Alternaria alternata IgE level
Measures specific IgE antibodies directed against Alternaria alternata. A detectable result indicates allergic sensitisation to this mould, but clinical relevance depends on whether exposure to Alternaria consistently corresponds with symptoms such as rhinitis, conjunctivitis, cough, wheezing or asthma.
Who May Benefit From the Alternaria alternata IgE Level Test?
This test may be suitable for people whose symptoms or exposure history suggest a possible IgE-mediated reaction to Alternaria alternata mould.
Symptoms associated with mould exposure - Targeted IgE testing may provide useful information when nasal, eye or respiratory symptoms repeatedly occur in mould-rich environments.
Persistent allergic rhinitis - Alternaria sensitisation may be considered where sneezing, nasal congestion or a runny nose cannot be fully explained by pollen or other common allergens.
Asthma with suspected environmental triggers - Mould-specific IgE may provide additional information where wheezing or asthma symptoms worsen in particular environments.
Symptoms in damp properties - Testing may help determine whether Alternaria-specific sensitisation is present, although damp buildings can also cause non-allergic irritation.
Seasonal respiratory symptoms - Alternaria spores can vary seasonally, making the pattern and timing of symptoms useful when interpreting the result.
Previous positive mould allergy testing - A targeted Alternaria measurement may help identify whether sensitisation extends specifically to this mould.
Multiple environmental allergies - People sensitised to pollen, dust mites or animal allergens may sometimes also have mould sensitisation.
Eczema alongside respiratory allergy symptoms - Atopic conditions commonly occur together, and targeted testing may provide additional information where mould exposure appears relevant.
Arrange a private mould allergy blood test - Access targeted Alternaria-specific IgE testing through London Blood Tests without requiring a large allergy panel.
How to Prepare
Do not stop asthma medication, antihistamines, adrenaline auto-injectors or other prescribed allergy treatment simply for this blood test unless specifically advised by the healthcare professional responsible for your care.
It can be useful to note whether symptoms occur mainly indoors or outdoors, at particular times of year, after gardening or specifically in damp buildings before discussing your result.
Symptoms and Reasons to Consider the Alternaria alternata IgE Level Test
You may wish to consider the Alternaria alternata IgE Level blood test if respiratory, nasal, eye or skin symptoms appear repeatedly after exposure to mould, damp environments or outdoor airborne spores.
Sneezing - Repeated sneezing following environmental exposure can occur with IgE-mediated allergic rhinitis.
Runny nose - Clear nasal discharge may accompany environmental allergy, although viral infections and non-allergic rhinitis can cause similar symptoms.
Blocked or congested nose - Persistent nasal congestion may occur with mould, pollen, house dust mite and other environmental allergies.
Itchy nose or throat - Itching can support an allergic pattern when it occurs consistently alongside exposure.
Red, itchy or watery eyes - Allergic conjunctivitis can accompany sensitivity to airborne mould spores.
Persistent cough - Airway irritation or allergic inflammation may contribute to coughing, although persistent cough requires consideration of many other causes.
Wheezing - Mould exposure may worsen symptoms in some people with allergic asthma and should be clinically assessed when recurrent.
Chest tightness - Respiratory allergy can sometimes accompany asthma symptoms, although chest tightness should never automatically be attributed to allergy.
Symptoms that worsen in damp environments - A consistent relationship between symptoms and a particular building or environment may make targeted mould testing more clinically relevant.
Symptoms during gardening or outdoor exposure - Alternaria spores can be present around vegetation, soil and decaying organic material and may become airborne outdoors.
A positive Alternaria-specific IgE result does not prove that mould is responsible for every symptom. The result becomes clinically meaningful when it matches a reproducible pattern of symptoms following relevant exposure.
Damp environments can also trigger respiratory irritation without an IgE-mediated allergy, and other allergens may coexist in the same environment. House dust mites, Aspergillus, Cladosporium, Penicillium and animal allergens may sometimes need to be considered depending on the history.
Significant breathing difficulty, severe wheezing, throat tightness, collapse, fainting or rapidly worsening respiratory symptoms require urgent medical assessment rather than waiting for routine allergy blood test results.
How to Book Your Alternaria alternata IgE Level Test
Booking your Alternaria alternata IgE Level test with London Blood Tests is simple and designed to fit around your schedule.

Attend your appointment
A trained professional will collect your blood sample safely and efficiently at the clinic or during your arranged home or hotel visit.
Laboratory analysis
Your sample is sent to the laboratory, where Alternaria alternata IgE level is measured using allergen-specific IgE analysis.
Receive your results securely
Your results are sent securely by email, ready to review yourself or discuss with a GP, allergist, respiratory specialist or other suitably qualified healthcare professional.
When Will I Receive My Results?
The expected turnaround time for the Alternaria alternata IgE Level test is approximately 2 business days.
Results are sent securely by email once laboratory analysis and authorisation are complete. Turnaround generally begins when the laboratory receives your blood sample rather than necessarily from the time it is collected.
Occasional repeat analysis, laboratory quality checks or sample-related issues can extend the expected turnaround.
Understanding Your Results
Your laboratory report will show the amount of Alternaria alternata-specific IgE detected in your blood, together with the laboratory's reporting range or sensitisation class where applicable.
A detectable or elevated result indicates that your immune system has produced IgE antibodies recognising Alternaria alternata. This demonstrates sensitisation, but it does not by itself prove that Alternaria causes symptoms whenever you encounter it.
The result becomes more clinically meaningful when it matches your history. For example, a positive result carries greater relevance if nasal symptoms, itchy eyes, cough or wheezing repeatedly worsen after mould exposure or during periods when airborne Alternaria spores are increased.
The numerical concentration does not reliably predict exactly how severe a future allergic reaction will be. Higher specific IgE can sometimes increase the likelihood that sensitisation is clinically relevant, but there is no single value that determines symptom severity for every individual.
A negative result makes IgE-mediated Alternaria sensitisation less likely but does not exclude allergy to other mould species or other environmental allergens. It also does not exclude non-IgE irritation caused by damp, mould spores or poor indoor air quality.
Total IgE and Alternaria-specific IgE measure different things. Total IgE reflects the overall concentration of IgE antibodies, while this test identifies IgE directed specifically towards Alternaria alternata.
Results should therefore be interpreted alongside symptoms, exposure history and, where appropriate, additional environmental allergen testing.
