When to Consider Allergy Testing
If you experience recurring, unexplained symptoms, an IgE blood test can help identify potential 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
Childhood Allergies
Eczema, feeding reactions or suspected food allergy in children
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 children and eczema-prone 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 testing is carried out at UKAS-accredited UK laboratories under the clinical governance of our CQC-registered clinic, with oversight by a GMC-registered doctor.
