Analysis device for determining an analyte in vivo in the body of a patient, having a measuring probe with a hollow needle (

18

) which can pierce through the skin. Light is passed through the hollow needle (

18

) and into the body via an optical fiber (

22

) travelling in the hollow needle (

18

). The light transported in the optical fiber (

22

) is modified in the measuring probe (

3

), the modification being characteristic of the presence of the analyte. A measurement and evaluation unit (

4

) measures the change to extract information concerning the presence of the analyte in the body. The hollow needle (

18

) is permeable, at least in a partial section of its length, serving as a measuring section (

30

) which can be inserted into the skin so that interstitial liquid may penetrate through the hollow needle wall to a measuring section of the optical fiber extending in the hollow needle (

18

) and the modification of the light characteristic of the presence of the analyte is effected through interaction with the interstitial liquid in the measuring section.
