Canine and feline screen
The canine and feline environmental screen incorporates the entire panel of environmental allergens assigned to five categories: grasses, weeds, trees, indoor and mites. The screen and panel contents are tailored to include the most relevant allergens (in terms of frequency of detection and degree of allergenicity). Panel contents are reviewed periodically to embrace shifts in allergen prevalence.
Flea and Malassezia are tested and reported individually making this screen an extremely cost-effective option.
A food screen is also available for dogs and cats and is reported as either positive (IgE/IgG present) or negative (IgE/IgG not detected). When screen results are positive individual allergens within that group (or groups) can be tested.
Negative screens do not rule out a diagnosis of a hypersensitivity disorder or adverse food reaction, these are clinical diagnoses. Testing individual allergens, however, is not appropriate for these cases thus avoiding unnecessary expense.
Screen tests are offered to increase flexibility; if preferred it is possible to test full environmental and food panels at the outset. Panels can be requested individually or in combination.

Canine and feline food panel
|Food panel||Beef, Milk, Lamb, Venison, Chicken, Egg,|
|Turkey, Pork, White fish, Blue (oily) fish,|
|Soya bean, Corn, Wheat, Rice, Potato,|
|Sugar beet, Carrot, Pea, Yeast, Oat|
3ml of serum is recommended for canine and feline tests.
The equine screen includes the allergens from the environmental panel, separated into outdoor and stable groups. The outdoor group contains common grasses, weeds and trees.
The stable group includes mites, moulds and dusts.
When screen results are positive individual allergens within that group (or groups) can be tested.
Negative screen results do not rule out a diagnosis of atopy or a hypersensitivity disorder – this is a clinical diagnosis. Testing individual allergens, however, is not appropriate for these cases thus avoiding unnecessary expense.
Allergens from the outdoor and stable groups are combined in the full environmental panel. Whilst the screen tests is offered to increase flexibility it is possible to choose the full environmental panel at the outset.
Equine food and insect panels are also available.

5ml of serum is recommended for equine tests.
Levels of serum IgE appear to increase rapidly in response to fly bites and decrease quickly when there are no flies in the environment. When testing horses to support a diagnosis of “sweet-itch” sampling during the fly-biting season (May – October) is recommended.
