Is an Allergy Test Right for You?
Recurring, unexplained symptoms are often the prompt. An IgE blood test can help narrow down possible triggers to discuss with your doctor.
Hay Fever & Rhinitis
Sneezing, itchy eyes, blocked nose, seasonal or year-round
Food Reactions
Hives, swelling, stomach upset or tingling after eating
Skin Reactions
Eczema flare-ups, hives or itching with an unclear trigger
Drug Sensitivities
Suspected reactions to penicillin or other antibiotics
Why an IgE Blood Test?
- No need to stop antihistamines, unlike skin-prick testing, blood IgE results are unaffected by allergy medication.
- One sample, many answers, hundreds of allergens can be screened from a single venous draw.
- Suitable for eczema-prone or sensitive skin, no skin exposure to allergens required.
Important to know
A positive IgE result shows sensitisation to an allergen, it does not by itself confirm a clinical allergy. Your written laboratory report should be interpreted by a GP or allergy specialist alongside your symptoms and history. All samples are analysed at UKAS-accredited UK laboratories by our nurse-led clinic.
