Device for testing a fluid

A device (1) for testing a fluid comprises an elongated carrier (3); two foam members (5a, 5b) for absorbing the fluid, which are arranged at an end (4) of the carrier (3); a positioning member (6) comprising a sleeve (7) which is slidably arranged on the carrier (3); and a diagnostic device (2), which is arranged in the positioning member (6), and which comprises a sensor die (40) adapted to detecting at least one property of the fluid and means for supplying the fluid to a sensitive surface of the sensor die (40). After the fluid has been supplied to the foam members (5 a, 5b), the positioning member (6) is moved towards the end (4) of the carrier (3) where the foam members (5a, 5b) are located. When the diagnostic device (2) comes into contact with one of the foam members (5a, 5b), the fluid is squeezed from the foam member (5a) and supplied to the sensitive surface of the sensor die (40), through the fluid supplying means of the diagnostic device (2).
