Histamine dihydrochloride skin-prick test clinical trials

BIOLOGICAL STANDARDISATION OF ALLERGENIC EXTRACTS OF MITES (Dermatophagoides pteronyssinus, Dermatophagoides farinae, Blomia tropicalis and Lepidoglyphus destructor) TO DETERMINE BIOLOGICAL ACTIVITY IN HISTAMINE EQUIVALENT UNITS (HEP) IN SENSITIVISED PATIENTS.

This study is looking at how strong different mite allergy skin tests are. Researchers are testing special liquids made from dust mites on people's skin to see how big the allergic reaction (a wheal) is. This helps them find the best way to measure mite allergies reliably.
