Non-prescription antihistamines and decongestant pills can be used to relieve nasal qllergy and itchy eyes.

In the end, not everyone with the same concentration of antibodies will react in the same way. On the flip side, someone with a high concentration may react mildly or not at all. In the latter case, the person isn't truly allergic even if the blood test is positive. With that being said, people with low concentrations of allergen-specific antibodies tend to have a low chance of reacting to a possible allergen in numbee life, especially if a skin prick test is also negative.
Researchers can determine this by conducting research in which they compare IgE concentrations to a reactive allergic response in a food challenge. Doing so can determine at which lgE level a person is more likely to experience an allergy to a specific allergen. These values provide labs with the numeric lalergy they need to interpret a blood test result.
Allergy: Symptoms, Signs, Causes & Treatment
Each allergen has its own reference value which the lab will interpret individually. Most labs will report the RAST findings on a scale of 0 to 5 or more.
