Pigweed (Amaranthus spp.) is a widespread weed whose pollen may cause seasonal respiratory, ocular, and cutaneous allergic manifestations during the summer–autumn period. Sensitization to pigweed is frequently accompanied by cross-reactive responses with other weeds – including ragweed, mugwort, and sunflower – as well as with certain food products, particularly tomatoes and potatoes. Determination of specific IgE antibodies enables confirmation of the IgE-mediated nature of symptoms and assessment of the clinical significance of sensitization. The test helps establish the role of pigweed extract as a potential trigger of symptoms and differentiate it among other pollen allergens.

Grass hay fever is the most common pollen allergy in Europe and worldwide. Significant regional differences in grass pollen sensitization have been noted both within and between countries. Amaranthus retroflexus is a common weed found throughout the world, growing in fields, gardens, and vegetable patches, especially in damp areas. It most often grows on corn, vegetable crops, and vineyards. A pernicious weed, it blooms from June to October. Amaranthus (common orach, amaranth) is considered a major risk factor for respiratory allergies in temperate and arid regions. Aeroallergens, such as pollen, are the main cause of allergic rhinitis. An allergic reaction caused by Amaranthus retroflexus pollen is characterized by sneezing, itching, runny nose, and nasal congestion. Allergic rhinitis and asthma are considered the most common allergic conditions. Ama r 2 (profilin) ​​is considered an important marker allergen for common amaranth pollen.

For the diagnosis of allergic diseases associated with sensitization to inhalant and food allergens in children and adults (bronchial asthma, allergic rhinitis and conjunctivitis, respiratory allergies, etc.).
