Biological Standardization of Chenopodium Album Allergen Extract
NCT01675349 · Status: COMPLETED · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 48
Last updated 2014-05-23
Summary
The objective of this study is to determine the biologic activity of a Chenopodium album allergen extract in histamine equivalent prick (HEP) units, in order to be used as in-house reference preparation (IHRP).
Conditions
- Allergy to Chenopodium Album
Interventions
- BIOLOGICAL
-
Prick test Chenopodium album allergen extract
This is an open, unblinded and non randomized biological as proposed by the Nordic Guidelines. Four concentrations of Chenopodium album allergen extract, together with a positive and negative control, using 10 mg/ml histamine dihydrochloride solution and a glycerinated phenol saline solution, respectively, will be tested in every patient in duplicate on the volar surface of the forearm. This test will be referred to as the Titrated Skin Prick test.
