Common follow-up tests

Almond IgEMeasures IgE antibodies to almond in your blood. A detectable result means your immune system has been sensitized to almond, which is not the same as an allergy.
Alpha-gal IgEMeasures IgE antibodies to alpha-gal, a sugar found in red meat and other mammal products. It is linked to a tick-related allergy that causes delayed reactions.

Ara h 8 (peanut) IgEMeasures IgE to Ara h 8, a peanut protein that looks like a birch pollen protein. It is generally linked to milder, mouth-area symptoms, though stronger reactions are not ruled out.

D. pteronyssinus (European house dust mite) IgEShows whether your immune system has made IgE antibodies to Dermatophagoides pteronyssinus, one of the two main house dust mite species.
Dog Dander IgEShows whether your immune system has made IgE antibodies to proteins from dog skin flakes, hair and saliva.
Egg White IgEMeasures IgE antibodies to egg white in your blood. A detectable result means your immune system is sensitized to egg, which is not the same as an allergy.
Elm IgEMeasures IgE antibodies to American elm pollen, one of several tree pollens that can cause sneezing, congestion and itchy eyes.
Gal d 1 ovomucoid (egg) IgEMeasures IgE to ovomucoid, the egg white protein that survives cooking, to help clinicians think about reactions to baked or cooked egg.
German Cockroach IgEMeasures IgE antibodies to German cockroach, an indoor allergen linked to year-round nose and eye symptoms and to asthma.
Hazelnut (Filbert) IgEMeasures IgE antibodies to hazelnut. A raised result can reflect a true hazelnut allergy or a milder pattern linked to birch pollen allergy.
Honey Bee Venom IgEMeasures IgE antibodies to honey bee venom, which helps clinicians work out whether a sting reaction may be linked to bee venom.
Horse Dander IgEMeasures IgE antibodies to horse dander, which can be linked to nose, eye and breathing symptoms around horses and, less often, away from them.
Immunoglobulin E (IgE), TotalTotal IgE is the overall amount of this allergy-related antibody in your blood. High levels are common with allergies, but the test can't show what you react to.
Johnson Grass IgEMeasures IgE antibodies to Johnson grass pollen, a grass of warm climates. A higher level means sensitization, which doesn't always cause symptoms.
Kentucky Blue Grass (June) IgEMeasures IgE antibodies to Kentucky bluegrass pollen. A higher level means sensitization, which doesn't always cause symptoms.
Latex IgEMeasures IgE antibodies to natural rubber latex. A higher level means sensitization to latex, which doesn't always cause reactions.
Milk IgEMeasures IgE antibodies to cow's milk proteins. A higher level means your body is sensitized to milk, which is not the same as having a milk allergy.
Mountain Cedar (Juniper) IgEMeasures IgE antibodies to mountain cedar pollen, a major winter allergen in parts of the US. A higher level means sensitization, which doesn't always cause symptoms.
Mugwort IgEMeasures IgE antibodies to mugwort pollen in your blood. A detectable result means you are sensitized, which is not the same as an allergy.
Oak IgEMeasures IgE antibodies to white oak pollen in your blood. A detectable result means you are sensitized, which is not the same as an allergy.
Olive Tree IgEMeasures IgE antibodies to olive tree pollen in your blood. A detectable result means you are sensitized, which is not the same as an allergy.

Pistachio IgEShows whether your immune system has made IgE antibodies to pistachio. This is called sensitization and doesn't always mean a pistachio allergy.
Rough pigweed IgEMeasures IgE antibodies to pigweed pollen, which shows whether your immune system has become sensitized to this late-summer weed.
Salmon IgEShows whether your immune system has made IgE antibodies to salmon. This is called sensitization and doesn't always mean a fish allergy.

White mulberry IgEMeasures IgE antibodies to white mulberry tree pollen, one of several tree pollens that can cause hay fever symptoms in spring.
