A medical device (1000) is presented for reduced-pain blood sampling and testing. The device comprises a housing (1070) defining a finger site (1010) for supporting a user's finger or a portion thereof within said finger site during the device operation； piercing, sampling and testing assemblies sequentially actuatable to successively initiate piercing, sampling and testing operational modes of the device； a carriage (1050) at least partially accommodated within said housing and being adapted for movement with respect to said finger site between its first position corresponding to the piercing mode of the device and a second position corresponding to the sampling and testing modes of the device, the device being thereby capable of operating in the piercing, sampling and testing modes while at a static position of the user's finger.
