About this test

This test measures Total IgE, a general marker of allergic tendency, alongside specific IgE antibodies to five antibiotics: Amoxicilloyl, Ampicilloyl, Cefaclor, Penicillin G and Penicillin V. Raised specific IgE to one of these is commonly used to indicate sensitisation to that antibiotic, which can be useful information to have on record before future prescriptions.

Its comparison group is made up of eight IgE allergy tests, but every other test in that group screens for food, pollen or environmental allergens rather than antibiotics, so this is the only antibiotic-specific test among them. On price it sits close to the middle, at £295 against a group median of £299.

It scores well for clarity, since the provider publishes a full description, sample type, collection route and turnaround, and around the middle for value for money and collection convenience, since it needs a venous draw at a clinic or from a visiting nurse. Results are not doctor-reviewed as standard, which limits the results and follow-up score.

Who is it for?

This suits people who have had a reaction to an antibiotic in the past, or who want a record of antibiotic sensitivities before starting a new course of treatment, rather than people looking for a general food or environmental allergy screen.

If you are looking for broader allergen coverage rather than antibiotics specifically, the other tests in this comparison group, such as Check My Body Health's Premium Allergy Test, cover a much wider range of food and environmental allergens for a lower price.

How it works

This test uses a venous blood sample, taken either at a clinic or by a visiting nurse. The sample is sent to the provider's laboratory, and results, covering Total IgE and specific IgE to five antibiotics, are typically ready within 2 working days. You view your results through the provider's secure online patient area, and its Patient Services team contacts you once they are available. Results are not doctor-reviewed as standard.

Pros & cons

Pros

  • Checks specific IgE reactions to five named antibiotics, not just a general allergy marker
  • Priced close to the median of its allergy comparison group, at £295 against £299
  • Results typically ready within 2 working days of the sample reaching the lab

Cons

  • Requires a venous blood draw rather than a self-collected finger-prick sample
  • Results are not doctor-reviewed as standard
  • Narrower in scope than general allergy panels in its comparison group, since it only covers antibiotics

Our editorial score

Compare Health Test Score Only antibiotic-focused test in its comparison group
Editorial confidence: 9.5/10

Total IgE and specific IgE reactions to five named antibiotics make up this test, the only antibiotic-focused test among the eight in its allergy comparison group. At £295 it is priced close to the group median of £299, though the other seven test food, pollen or environmental allergens rather than antibiotics. Results are not doctor-reviewed as standard.

Score breakdown

  • Clarity and documentation 9.0/10
