A test cartridge includes an adjustable lancet. The adjustable lancet is controlled by a controller. The adjustable lancet automatically detects a subject's finger, adjusts the lancet's height, pricks the finger to draw blood, moves a tube to collect the blood, moves the tube away from the finger, and empties the blood from the tube into a vial or receptacle. The adjustable lancet may include safety features to prevent the lancet to trigger when the subject's fingernail is facing the lancet, to control the amount that the lancet pierces the subject's finger, and/or to prevent the reuse of a test cartridge for multiple persons or multiple times by the same person. The adjustable lancet may include a massager wheel and/or a pressure bar to rub the subject's finger after the finger is pierced to facilitate drawing of the blood from the finger.
