Medical diagnostic devices and methods

1. A method of operating a blood glucose meter, the method comprising:

receiving and processing time data transmitted wirelessly with the blood glucose meter;

performing a plurality of tests with the blood glucose meter;

correlating a plurality of glucose concentration measurement values derived from the tests with particular points in time or intervals of time during the day to establish a predetermined range of typical glucose measurement values associated with a particular point in time or time interval; and

alerting the user when a measured glucose value falls outside of the predetermined range of typical glucose measurements.

2. A method of monitoring and treating diabetes with the assistance of a blood glucose meter, the method comprising:

receiving and processing time data transmitted wirelessly with the blood glucose meter;

performing at least one test with the blood glucose meter thereby creating a blood glucose concentration measurement value;

correlating the glucose concentration measurement value with the particular point in time during the day when the test was performed; and

automatically identifying the glucose concentration measurement value as being associated with either a pre-prandial test or post-prandial test based at least in part on the correlated time associated with the value, or prompting the user to identify the glucose concentration measurement value as being associated with either a pre-prandial test or post-prandial test.

3. The method of claim 2 , wherein the blood glucose meter comprises predefined time intervals associated with either a pre-prandial test or post-prandial test.

4. The method of claim 2 , further comprising programming the blood glucose meter to define the pre-prandial test and post-prandial test time intervals.

5. A method of monitoring and treating diabetes with the assistance of a blood glucose meter, the method comprising:

receiving and processing time data transmitted wirelessly with the blood glucose meter;

performing a plurality of tests with the blood glucose meter;

correlating glucose concentration measurement values derived from the tests with the particular points in time during the day when they were taken to establish a data set;

downloading the data set from the blood glucose meter;

deriving trends based on the downloaded glucose concentration values and associated time data; and

prescribing treatment based at least in part on the trends.

6. A method for operating a medical diagnostic device, the method comprising:

receiving and processing time data transmitted wirelessly, wherein receiving and processing time data comprises comparing time data currently stored within the device with time data obtained from at least one wireless time data transmission.

7. The method of claim 6 , wherein receiving and processing time data further comprises overwriting the time data currently stored within the device with time data obtained from at least one wireless time data transmission upon detection of a discrepancy therebetween.

8. The method of claim 6 , wherein the time data is transmitted via airwaves.

9. The method of claim 8 , wherein the time data is transmitted from at least one of the following sources: radio broadcast data stream (RBDS); global positioning system (GPS); wireless fidelity network (WiFi); and the National Atomic Clock signal.

10. The method of claim 6 , wherein receiving and processing time data comprises scanning the local area for wireless time data transmissions, calculating a signal-to-noise ratio for each wireless time data transmission received, and comparing the signal-to-noise ratio of a plurality of wireless time data transmissions received by the device.

11. The method of claim 10 , wherein receiving and processing time data further comprises storing a plurality of frequencies as a data file.

12. The method of claim 10 , wherein receiving and processing time data further comprises automatically and incrementally increasing the time between scanning the local area for wireless time data transmissions upon encountering difficulty in acquiring signals of a predetermined acceptable quality.

13. A medical diagnostic device comprising a wirelessly transmitted time data receiver and processor, wherein the receiver and processor are configured for scanning the local area for wireless time data transmissions, calculating a signal-to-noise ratio for each wireless time data transmission received, and comparing the signal-to-noise ratio of a plurality of wireless time data transmissions received by the device.

14. The device of claim 13 , wherein the medical diagnostic device comprises an integrated glucose meter.

15. The device of claim 13 , further comprising an antenna.

16. The device of claim 13 , wherein the receiver and processor comprises an integrated circuit.

17. The device of claim 13 , wherein the receiver and processor are further configured to store a plurality of frequencies as a data file.

18. The device of claim 13 , wherein the receiver and processor are further configured to automatically and incrementally increase the time between scanning the local area for wireless time data transmissions upon encountering difficulty in acquiring signals of a predetermined acceptable quality.

19. The device of claim 13 , wherein time data is transmitted via airwaves.

20. The device of claim 13 , wherein time data is transmitted from at least one of the following sources: radio broadcast data stream (RBDS); global positioning system (GPS); wireless fidelity network (WiFi); and the National Atomic Clock signal.

21. The device of claim 13 , wherein the receiver and processor are further configured to compare time data currently stored within the device with time data obtained from at least one wireless time data transmission.

22. The device of claim 21 , wherein the receiver and processor are further configured to overwrite time data currently stored within the device with time data obtained from at least one wireless time data transmission upon detection of a discrepancy therebetween.
