An allergy blood test measures specific IgE, the antibody the immune system makes against a trigger, for pollens, dust mites, pets, moulds or foods. At The Wellness in Marylebone it costs from £395, as the Foundation Screen, with results within days and a doctor to explain the result.
An allergy blood test measures specific IgE, the antibody the immune system makes against a trigger, for pollens, dust mites, pets, moulds or foods. The molecular profile measures IgE against around 300 separate allergen components from one sample.
It helps when symptoms such as hay fever, wheeze, hives or swelling seem linked to a trigger, and when skin prick testing is not suitable.
A positive result shows sensitisation, which is not always the same as allergy, so the result is read against what actually happens when you meet the trigger.
Antihistamines do not affect a blood test, so there is no need to stop them. No fasting is needed.
No. Intolerance does not involve IgE, and no blood test reliably diagnoses it. We do not offer an intolerance test.
The Foundation Screen covers one trigger group, airborne or food. The Comprehensive Screen covers both, and the molecular profile separates a true allergy from a harmless cross reaction.
Choose a screen and a time for the draw. A doctor reads the result before it reaches you, and rings or writes with what it means and what to do next. Or ring 020 3951 3429.
