A phlebotomy device (10) includes a needle (12) defining a lumen and having a proximal end portion (30) and a distal end portion (38). The distal end portion includes a sharpened tip (42) configured to pierce tissue. The phlebotomy device further includes a sensor (14) disposed at least partially within the lumen. The sensor has a first state and a second state and is configured to transition from the first state to the second state upon exposure to blood at physiological temperature. |
