Overview
Grass pollens are the principal causes of respiratory allergic disease globally. The IgE reactivity to these allergens is manifested by about 40% of allergic patients and 20% of the general population. Timothy grass (Phleum pratense) is one of the most common grass species that produces pollen allergens.
Allergenicity of timothy grass results from a number of allergen components, such as Phl p 1, 2, 4, 5, 6, 7, 11, 12, and 13. Among these allergen molecules, Phl p 1 is the most important and the key allergen of timothy grass triggering specific IgE reaction in more than 90% of sensitized individuals, followed by Phl p 5 affecting 65-90% of grass pollen allergic patients. Phl p 12 sensitization was found to increase with age. The allergen molecules of timothy grass show extensive cross-reactivity with grasses belonging to the family Poaceae and subfamily Pooideae and some corn and maize species.
An allergy to Timothy grass triggers a reaction in an individual's immune system. The body views certain substances as toxic and produces IgE antibodies to these contaminants. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction.

Frequently Asked Questions
- Establishing a diagnosis of an allergy to Timothy grass
- Identifying allergens responsible for allergic disease and/or anaphylactic episode
- To confirm sensitization prior to beginning immunotherapy
Common signs or symptoms of Timothy grass allergy may include the following:
- Hives or skin rashes
- Itching/swelling
- Severe dizziness
- Trouble breathing
- Fast heartbeat
A severe, possibly life-threatening allergic reaction known as anaphylaxis may occur in some cases. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis may include:
- Rapid or increased pulse
- Swollen throat or lump, making it difficult to breathe
- Low blood pressure
- Extreme dizziness or loss of consciousness
Specific IgE measures the concentration of circulating allergen specific IgE for grass pollen allergen Timothy grass.
This test requires a blood sample. A tourniquet (elastic) band is placed tightly on the upper arm. The patient is then asked to make a fist. This helps in the build-up of blood filling the veins. The skin is disinfected before needle insertion and the blood sample is collected in vacutainer
Detection of IgE antibodies indicates an increased likelihood of allergy to Timothy grass that may be responsible for eliciting signs and symptoms. A negative result indicates that the symptoms are not due to Timothy grass allergies and other differential diagnoses must be considered.
