To perform the measurement, a tester is rubbed over the surface, e.g. of the bed, for one minute. A solution is then dripped onto the collected dust particles and after just ten minutes, the tester will reveal whether your level of allergen exposure is harmful. The whole test is quick and reliable, and involves no direct contact with the allergen and no chemicals. The compact wipe test is used to collect, prepare and analyse the dust particles, directly displaying the result of the test.
