The controller includes a timing module configured to initiate delivery of a drug in time and to adjust delivery according to the received information. Other devices, systems, and methods are disclosed. ## Claims ### Claim 1 An apparatus comprising: an input configured to receive blood glucose data, wherein the blood glucose data is obtained during a number of specified blood glucose testing times; to user interface; and a controller commicatively coupled to the input, and the user interface, wherein the controller includes: blood glucose data module configured to calculate statistical measure of blood glucose variability of the user from the blood glucose data, and wherein the controller is configured to automatically adjust a blood glucose testing time from a previously stored testing time in response to the measure of blood glucose variability. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the controller includes: a comparison module configured to compare the calculated measure of blood glucose variability to a threshold blood glucose variability value, and wherein the controller is configured to increase the number of blood glucose testing times if the measure of blood glucose variability exceeds a blood glucose variability target value by more than a first threshold blood glucose variability value, and decrease the number of blood glucose testing times if the measure of blood glucose variability is less than the blood glucose variability target value by more than a second threshold blood glucose variability value. ### Claim 3 (depends on 1) The apparatus of claim 1, including a memory communicatively coupled to the controller to store an indication of a user preference for a blood glucose testing time, and wherein the controller is configured to adjust the blood glucose testing time according to the indication. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein the controller is configured to schedule a plurality of blood glucose testing times according to the indication. ### Claim 5 (depends on 1) The apparatus of claim 1, including a blood glucose monitor communicatively coupled to the input and configured to test blood glucose in response to a prompt received from the controller. ### Claim 6 (depends on 1) The apparatus of claim 1, including a communication port coupled to the input and configured to receive blood glucose data from a device separate from the blood glucose management device, and wherein the controller is configured to communicate an adjusted blood glucose testing time to the separate device. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the user interface includes a display, wherein the controller is configured to prompt a user, via the display, to test blood glucose at an adjusted time using a separate device. ### Claim 8 (depends on 7) The apparatus of claim 7, wherein the user interface is configured to receive manual entry of the blood glucose data from the user. ### Claim 9 (depends on 1) The apparatus of claim 1, including: a pump communicatively coupled to the controller and configured to deliver insulin, and wherein the controller is configured to adjust the blood glucose testing time in response to the measure of blood glucose variability and according to times of insulin delivery.
