Process for the preparation of a unit for the determination of residues of antibiotics and sulphas in biological liquids, the unit thus prepared and process for carrying out the determination. Spores of a microorganism showing a broad sensitivity for the antibiotics and sulphas to be tested are introduced into an agar solution so that they cannot germinate but stay alive, while by addition of a small amount of trimethoprim the sensitivity for sulphas is increased, whereafter the agar solution is allowed to solidify in tubes of preferably transparent material. The unit is very useful for the determination of residues of antibiotics and sulphas in, e.g. milk by less skilled persons.
