Hello, the blood test did not come out for an allergy test, we have to repeat (it's about a 1.5-year-old child) but we gave him two doses of Contrahist of course we stop having another blood test, my question is whether we have to wait 7-14 days or can we do the test earlier.

Antiallergic drugs do not affect the result of serological tests for allergies (so-called blood tests). There is no need to maintain an interval of 7-14 days from administration of the drug to the test. Contrahist only affects the results of the so-called skin tests and it is before this examination that antihistamines should be discontinued.
