American House Dust Mite (D.farinae)
IgE antibodies to the American house dust mite.
Why it matters
A second common dust mite species; testing both gives a fuller picture.
Price is for one test. No subscription.
The Chxhealth Allergy Enhanced Panel is a blood test for suspected immediate (Type I) allergy. It measures IgE antibodies to 17 allergens across pets, house dust mites, pollens and foods, including peanut, hazelnut, sesame, soya, cod, shrimp, egg and milk, plus your Total IgE.
It includes every allergen on the First-Line Panel and adds a second dust mite, dog dander, mugwort pollen, hazelnut, cod, shrimp, egg yolk, soya and sesame. Randox Laboratories says it could pick up around 90% of the IgE allergies typically seen in UK primary care. It suits people who need a broader picture than the First-Line Panel gives.
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.
Sample requirements
Collected at either our Chxhealth clinic in Lanchester (book your appointment during checkout) or at one of our 50+ UK partnered clinics (you'll receive a separate booking email after checkout). Phlebotomy fee included in the price.
IgE antibodies to the American house dust mite.
A second common dust mite species; testing both gives a fuller picture.
IgE antibodies to cat skin and dander.
Cat allergen is light, sticky and widespread, even in homes without a cat.
IgE antibodies to dog dander.
Dog dander carries proteins that can trigger sneezing, itchy eyes and wheeze.
IgE antibodies to dog skin (epithelium).
One of two dog extracts; together they give a fuller view of dog sensitisation.
IgE antibodies to the European house dust mite.
The most common dust mite in UK homes and a frequent cause of year-round symptoms.
IgE antibodies to cod proteins.
Fish allergy often affects several species, and cod is a common reference fish.
IgE antibodies to egg yolk proteins.
Adds to the egg white result, as yolk contains some different egg proteins.
IgE antibodies to egg white proteins.
Egg white holds most of the proteins behind egg allergy, common in young children.
IgE antibodies to hazelnut proteins.
Hazelnut is a common tree nut allergen and can be linked with birch pollen.
IgE antibodies to cow's milk proteins.
Cow's milk is one of the most common food allergens, especially in early childhood.
IgE antibodies to peanut proteins.
Peanut is one of the most common causes of food allergy in the UK.
IgE antibodies to sesame seed proteins.
Sesame is one of the 14 major allergens that UK food labels must declare.
IgE antibodies to shrimp (prawn) proteins.
Shellfish allergy often starts in adulthood and can be linked with dust mite.
IgE antibodies to soya bean proteins.
Soya is a major labelled allergen and is found in many processed foods.
IgE antibodies to mugwort (weed) pollen.
A late-summer weed pollen that can keep hay fever going after the grass season.
IgE antibodies to silver birch tree pollen.
Birch is a major spring hay fever trigger in the UK and is linked with some foods.
IgE antibodies to Timothy grass pollen.
Grass pollen is the most common cause of hay fever in the UK.
The total amount of IgE antibody in your blood.
Gives context for the allergen-specific results; raised levels are common in atopy.
Total IgE is the overall amount of IgE antibody in your blood. It helps a clinician interpret the 17 allergen-specific results. For example, a very high total IgE can come with low-level positive results to several allergens that may not all be clinically important. On its own, total IgE cannot tell you what you are allergic to.

The European house dust mite is the most common species in UK homes, but the American house dust mite is also found here. The two share many proteins, yet some people show a stronger response to one than the other. Testing both gives a fuller picture of dust mite sensitisation, which is often behind year-round nasal or chest symptoms.

They are two different extracts, prepared from different sources on the dog, and each contains its own mix of dog proteins. Some people respond more to one than the other, so testing both makes it less likely that a dog sensitisation is missed. A clinician reads them together alongside your symptoms around dogs.

Egg white contains most of the proteins linked with egg allergy, but the yolk has some different proteins of its own. Testing both gives a more complete view of egg sensitisation. A clinician reads the two results together with your history, including whether you react to raw, lightly cooked or well-cooked egg.

Yes. Some hazelnut proteins look similar to birch pollen proteins, so people with birch hay fever can test positive to hazelnut. In some, this causes only mild itching in the mouth with raw nuts; others have a true hazelnut allergy that can be more serious. A whole-hazelnut result cannot tell these apart, so a clinician needs your history.

Sesame is one of the 14 major allergens that UK food businesses must declare on labels. It is found in bread, tahini, hummus, oils and many Asian and Middle Eastern dishes, which can make it hard to avoid without realising. This marker measures IgE to sesame seed proteins.

Yes. Shellfish allergy often appears for the first time in adults. Shrimp contains a protein called tropomyosin that is similar in other crustaceans and in house dust mites, so sensitisation to one can show up alongside the others. This marker measures IgE to shrimp. A clinician interprets it with your history of eating shellfish.
More about Shrimp
Not necessarily. Many fish share a protein called parvalbumin, so people sensitised to cod are often sensitised to other fish too, but not always. This marker measures IgE to cod. A clinician will consider which fish you have eaten safely and may suggest further assessment before you add or remove any fish.

Soya is one of the 14 major allergens on UK food labels and is widely used in processed foods, plant-based products and infant formulas. Soya proteins can resemble peanut and birch pollen proteins, so a positive result needs careful reading. This marker measures IgE to soya bean proteins.

Mugwort is a common weed found on roadsides and waste ground. Its pollen is released in late summer, usually July to September, so it can keep hay fever symptoms going after the grass season ends. Mugwort sensitisation can also be linked with reactions to celery and some spices.

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

It measures IgE to 17 allergens. The animal allergens are cat, dog dander, dog epithelium and two house dust mites. The foods are cod, egg yolk, egg white, hazelnut, milk, peanut, sesame seed, shrimp and soya bean. The pollens are mugwort, silver birch and Timothy grass. Total IgE is also measured to give the results context.
It contains all 8 First-Line allergens and adds 9 more, raising Randox's estimated coverage from roughly 80% to up to about 90% of IgE allergies seen in UK primary care. The Complete Panel goes further, with 63 allergens including more foods, tree and grass pollens, small pets and moulds. Focused food, pollen, pet and mould panels are also available.
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.
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.
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: for example, someone can have IgE to hazelnut or soya because of birch pollen and still eat those foods without trouble. 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.
They measure different antibodies. The Enhanced Panel looks for IgE, the antibody behind immediate allergic reactions, to 9 foods including peanut, hazelnut, sesame, shrimp and cod. Food Sensitivity measures IgG to 207 foods. IgG is not IgE, and Food Sensitivity does not test for immediate allergy, so it cannot tell you whether you are allergic to a food. If you suspect a food allergy, an IgE test is the relevant one.
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.
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.
