Price is for one test. No subscription.

The Chxhealth Allergy Mould and Fungal Panel is a blood test for suspected immediate (Type I) mould allergy. It measures IgE antibodies to 7 moulds and yeasts: Alternaria, Aspergillus fumigatus, Cladosporium, Penicillium, Candida albicans, baker's yeast and brewer's yeast, plus your Total IgE.

It suits people whose nasal or chest symptoms seem worse in damp buildings, around compost or leaves, or in late summer and autumn. It has the same moulds and yeasts as the Complete Panel. It measures IgE in your blood; it does not test your home for mould or check for a fungal infection.

Your sample is a venous blood draw at our Lanchester clinic in County Durham or one of 50+ UK partner clinics, analysed by Randox Laboratories, accredited by UKAS to ISO 15189. Results take up to 5 working days. Your report shows sensitisation for a clinician to read alongside your symptoms; Chxhealth does not diagnose, treat or prescribe.

IgE antibodies to the mould Penicillium.

Why it matters

A common indoor damp mould; this is not a test for penicillin allergy.

Total IgE

The total amount of IgE antibody in your blood.

Why it matters

Gives context for the allergen-specific results; raised levels are common in atopy.

Biomarker FAQs

Questions about these biomarkers.

Why is Total IgE measured on the mould panel?

Total IgE is the overall amount of IgE antibody in your blood. It is not specific to any mould, but it helps a clinician read the 7 mould and yeast results in context. A raised total IgE is common in people with asthma, eczema or other allergies, while a normal level does not rule out a mould allergy.

More about Total IgE

What is Alternaria?

Alternaria is a common outdoor mould found on plants, soil and decaying vegetation. Its spores are highest in summer and early autumn, especially on warm, dry, windy days. Sensitisation to Alternaria has been linked with asthma. This marker measures IgE to Alternaria tenuis, now often called Alternaria alternata.

What is Aspergillus fumigatus?

Aspergillus fumigatus is a mould found in soil, compost, rotting leaves and damp buildings. Most people breathe in its spores every day without problems. In some people with asthma, sensitisation can be relevant to conditions a respiratory specialist may want to look into. This marker measures IgE to Aspergillus fumigatus.

More about Aspergillus fumigatus

Is baker's yeast a food or a mould allergen?

It can be both. Baker's yeast is eaten in bread and baked goods and can be inhaled as dust in bakeries. It is a yeast, part of the fungal family, which is why it sits on this panel. IgE allergy to yeast is uncommon. This marker measures IgE to baker's yeast.

More about Baker's yeast

What is the difference between baker's and brewer's yeast?

Both are strains of the same yeast species, Saccharomyces cerevisiae, used for different jobs. Brewer's yeast is used in beer and yeast extracts and is sold as a supplement. Because they are so closely related, results are often similar. This marker measures IgE to brewer's yeast.

Does a Candida result mean I have a yeast infection?

No. Candida albicans lives normally on the skin and in the gut and mouth of most people. This marker measures IgE sensitisation to Candida. It does not test for thrush, infection or so-called candida overgrowth. If you think you have an infection, speak to your GP or pharmacist.

What is Cladosporium?

Cladosporium is one of the most common moulds in outdoor air in the UK, especially in summer. It grows on plants, soil and leaves, and indoors on damp window frames and bathroom surfaces. It can contribute to sneezing, a blocked nose and wheeze. This marker measures IgE to Cladosporium herbarum.

Does a positive Penicillium result mean I am allergic to penicillin?

No. Penicillium is a mould, the blue-green growth often seen on old bread, fruit and damp walls. This marker measures IgE to the mould itself. Penicillin antibiotic allergy is a separate drug allergy that this panel does not test. Never stop or take an antibiotic because of this result.

Is this panel right for me?

Who this panel is built for.

Who this is for

Adults whose sneezing, blocked nose or wheeze seem worse in damp or mouldy places.
People whose symptoms flare in late summer and autumn, or around compost and leaves.
Anyone who cannot easily stop antihistamines for skin-prick testing.

Consider speaking to a clinician first

Anyone who has had a severe allergic reaction (anaphylaxis). Speak to your GP, who can refer you to an NHS allergy clinic.
People wanting to check their home for mould. This is a blood test for IgE, not an environmental test.
People with suspected thrush or another fungal infection. This panel does not test for infection; see your GP.
Anyone under 18. Chxhealth tests are for adults.

This panel reports biomarker data. It does not diagnose any condition. Your results should be reviewed alongside the advice of your GP or another qualified healthcare professional.

Booking and results

Before and after your test.

How do I book my appointment?

After you order, you will receive an email with a link to book your appointment. You can choose the Chxhealth clinic in Lanchester, County Durham, or one of our 50+ UK partner and pop-up clinics. View all clinic locations.

Do I need to pay for the phlebotomist?

No. The phlebotomy fee is included in the price. There are no hidden costs at the appointment.

Do I need to fast before my blood test?

It isn’t required, but for tests that include glucose, lipids (cholesterol) or insulin, fasting is recommended for the best results. If you fast, drink water only. If you have diabetes or another medical condition, check with your GP before fasting. If you’d rather not fast, that’s fine: just let us know at your appointment.

Should I keep taking my medication before the test?

Yes, keep taking your medication as normal. Some medicines can affect particular markers; for example, blood thinners such as aspirin or warfarin can affect clotting tests. If you are unsure, contact us before booking.

Which laboratory analyses my sample?

Samples are analysed by Randox Laboratories, a UK clinical laboratory accredited by UKAS to ISO 15189.

How will I receive my results?

You will receive a plain-English PDF report by email. It shows each biomarker, your result, the reference range the laboratory uses and a short explanation of what each marker measures.

Can I share my results with my GP?

Yes. The PDF report is designed to be shared. You can email or print it for your GP or another healthcare professional.

Can this test diagnose a condition?

No. Chxhealth is a biomarker and genetic data provider; we do not diagnose, treat or prescribe. Your report shows where your results sit against the reference range, and anything outside the typical range is flagged so you can follow it up with a healthcare professional.

How is my health data handled?

Chxhealth complies with UK GDPR. Your personal data and results are stored in encrypted, UK-based systems and are never shared with third parties without your explicit consent. You can ask for your data to be exported or deleted at any time.

Can I cancel or get a refund?

If you cancel before your sample has been taken, we offer a full refund. Once your sample has been taken and sent to the laboratory, a refund is not possible because the lab work has been done. See our refund policy for full terms.

About this test

Questions about this test.

What does the Allergy Mould and Fungal Panel test for?

It measures IgE to 7 moulds and yeasts: Alternaria tenuis, Aspergillus fumigatus, baker's yeast, brewer's yeast, Candida albicans, Cladosporium herbarum and Penicillium notatum. Total IgE is also measured. Each result is reported separately, so you can see which moulds or yeasts you are sensitised to.

How does the Mould and Fungal Panel compare with the other allergy panels?

It is the only focused mould panel. The First-Line and Enhanced panels do not include any moulds or yeasts. The Complete Panel includes all 7 of these, plus foods, pollens, animals and dust mites. Choose this panel if mould is your main suspect, or the Complete Panel if your symptoms could have several causes.

Do I need to stop antihistamines before the Mould and Fungal Panel?

No. Antihistamines affect skin-prick testing because they dampen the skin's reaction, but they do not interfere with an IgE blood test in the same way. That is one reason a blood test can suit people who cannot easily stop their antihistamines. Keep taking any medicine you have been prescribed unless the clinician who prescribed it tells you otherwise.

Is the Mould and Fungal Panel better than a skin-prick test?

Neither is better in every case. A skin-prick test is done in clinic and read within minutes. A blood test measures IgE in a serum sample instead, so it can suit people who cannot stop antihistamines, have widespread eczema or are at higher risk of a severe reaction to testing. Both show sensitisation and both need reading alongside your symptoms.

What does a positive result on the Mould and Fungal Panel mean?

A positive result means your immune system has made IgE antibodies to that allergen. This is called sensitisation, and it is not the same as a confirmed allergy: mould spores are everywhere, and many people with IgE to a mould have few or no symptoms. A negative result makes an IgE allergy less likely but does not completely rule one out. A clinician should interpret your results alongside your symptoms and history.

Does the Mould and Fungal Panel test for a fungal infection or mould in my home?

No. It measures IgE antibodies in your blood, showing whether your immune system is sensitised to these moulds and yeasts. It does not detect a fungal infection such as thrush, and it cannot tell you whether your home has a mould problem. Speak to your GP about possible infections and your landlord or a surveyor about damp.

How long do Mould and Fungal Panel results take?

Results take up to 5 working days. Your sample is a venous blood draw (2 serum tubes), taken at the Chxhealth clinic in Lanchester, County Durham, or at one of our 50+ UK partner clinics. There is no at-home kit for this test. Your report shows your IgE result for each allergen on the panel and your Total IgE.

What happens after I get my Mould and Fungal Panel results?

Share your report with your GP or another clinician, who can read it alongside your symptoms. They may suggest further assessment or a referral to an NHS allergy clinic. Chxhealth does not diagnose, treat or prescribe. Please do not cut foods out of your diet or make big changes at home based on a result alone, without clinical advice.

Is this a subscription?

No. The price covers one test. If you would like to test again later, you simply book a new one.
