An apparatus for taking an intestinal sample of a human or animal patient comprises a holder part ( 1 ) and an expandable part ( 2 ) supported by the holder part and having one or more sampling areas ( 8 ) on the surface thereof. The expandable part ( 2 ) is in a non-expanded state rectally insertable into and retractable from the patient's intestine, and in an expanded state, inserted into the patient's intestine, the expandable part is capable of contacting the intestinal wall with at least one sampling area ( 8; 14 ). The apparatus further comprises protective livers ( 7 a , 7 b ) for preventing said sampling area or areas ( 8 ) from contact with the intestinal wall and intestinal fluid at least when the expandable part ( 2 ) in the non-expanded state is being rectally inserted into the patient's intestine. |
