Lamb's Quarters (Goose Foot) Allergy IgE Blood Test

What is the purpose of this test?

Order this Lamb's Quarters (Goose Foot) Allergy IgE Blood Test, which measures the IgE antibody levels in the blood to detect an allergy to lamb's quarters (goosefoot). The Goosefoot plant, also known as Chenopodium album, is an annual plant that can grow up to 1.5 meters tall. It's wind-pollinated and produces up to 20,000 pollen grains in a season. Its pollination period usually occurs between July and September. The plant can be found in various habitats, such as brush burns, cultivated fields, desert grasslands, juniper-pine forests, overgrazed lands, and logged openings. Although it originated from Eurasia, it is now naturalized throughout North America. Unfortunately, the pollen from this plant can cause allergic reactions like conjunctivitis, allergic rhinitis, and asthma. The IUIS database lists three allergens in Goosefoot weed pollen: Che a 1, Che a 2, and Che a 3. Moreover, this pollen can cause cross-reactivity with other plants in the Chenopodiaceae family, as well as alder, birch pollen, black locust, lilac, sugar beet, timothy grass, and olive.

What causes an allergy to Lamb's Quarters (Goose Foot)?

Lamb's quarters (goosefoot) allergies are triggered by a hypersensitive individual inhaling its pollen. These allergens may trigger a response in their immune system since the body views certain substances as harmful, producing IgE antibodies to combat these invaders. Unfortunately, these antibodies cause histamine to be released, resulting in the symptoms associated with an allergic reaction.
