1. A process for detecting the incidence of domestic dust containing allergens, as it occurs when domestic dust mites are or were present, characterized in that samples of dust, present in buildings, are completely suspended in an aqueous alcohol solution of alkali metal hydroxide and in that a colour-differing reaction is carried out with the resultant extract, by means of an aromatic diazo compound, and the colour reaction, if it occurs, being taken as evidence that the dust contains residue of domestic dust mites. |
