Key similarities and differences between the two sample types:

  • The tests cost the same to analyse
  • In the blood draw test, food reactions are grouped from 1 (mildest reaction) to 4 (strongest reaction) based on the strength of reaction, so you will get 4 levels of sensitivity
  • The capillary test combines groups 1 and 2 but shows groups 3 and 4 separately, so you will get 3 levels of sensitivity
  • The capillary test avoids additional expenses for the blood draw and courier.
