The test products used in the study are allergen extracts from these mites, given as a skin prick test, along with a negative control made of sodium chloride and a positive control made of histamine dihydrochloride. The purpose of the study is to find out how well different amounts of these mite extracts can detect allergy and how accurate the test is.

During the study, small drops of the test solutions are placed on the skin, and the skin is lightly pricked. This is done with the different mite extracts and with the control solutions. The skin is then checked for a local reaction, such as a small raised area called a wheal, which means a swollen bump on the skin. The study also looks at safety, including any skin reactions or other unwanted effects after the test.

The study is short and is expected to take place over a few months. It focuses on comparing the reactions caused by the different allergen extracts so that the best test strength can be identified for diagnosing these mite allergies.
