1. An apparatus, comprising: a glucose sensor having a first sensing area and a second sensing area configured for fluid contact with biofluid under a skin surface for monitoring glucose level in the biofluid;one or more processors operatively coupled to the glucose sensor; anda memory operatively coupled to the one or more processors and configured to store instructions which, when executed by the one or more processors, receives a first and second signals respectively from the first and second sensing areas of the glucose sensor, detects a dropout in a signal level associated with one of the first signal or the second signal, compares the first signal and the second signal to determine a variation between the first signal and the second signal, the dropout is detected, confirms the one of the first signal or the second signal as a valid glucose sensor signal corresponding to the monitored glucose level when the determined variation between the first signal and the second signal is less than a predetermined threshold level, determines a glucose level based on the valid glucose sensor signal, and provides the determined glucose level for output on a display. 2. The apparatus of claim 1, wherein when the variation between the first signal and the second signal is not less than the predetermined threshold level, the memory storing instructions which, when executed by the one or more processors, confirms the first signal or the second signal as invalid sensor output signals. 3. The apparatus of claim 1, wherein when the variation between the first signal and the second signal exceeds the predetermined threshold level, the memory storing instructions which, when executed by the one or more processors, performs a rate of change determination of signals from one of the first sensing area or the second sensing area, and confirms the one of the first signal or the second signal as the valid glucose sensor signal when the determined rate of change level is less than a predetermined rate threshold level. 4. The apparatus of claim 3, wherein the rate of change determination is performed on signals, from the one of the first or the second sensing areas, that are larger in magnitude. 5. The apparatus of claim 3, wherein, when the determined rate of change level is greater than the predetermined rate threshold level, the memory storing instructions which, when executed by the one or more processors, confirms the first and the second signals as invalid sensor signals. 6. The apparatus of claim 1, wherein the biofluid includes one or more of interstitial fluid or dermal fluid. 7. The apparatus of claim 1, wherein the valid glucose sensor signal is the larger signal between the first signal and the second signal. 8. The apparatus of claim 1, wherein the memory operatively coupled to the one or more processors and configured to store instructions which, when executed by the one or more processors, confirms the one of the first or second signals is an invalid signal. 9. The apparatus of claim 1, wherein when the variation between the first and the second signals exceeds the predetermined threshold level, the memory operatively coupled to the one or more processors and configured to store instructions which, when executed by the one or more processors, confirms the first and second signals as invalid sensor output signal. 10. The apparatus of claim 1, wherein at least a portion of the glucose sensor with the first sensing area and the second sensing area are in fluid contact with the biofluid. 11. The apparatus of claim 1, wherein the first sensing area is separated by a predetermined distance from the second sensing area such that glucose sensor signal attenuation is minimized. 12. The apparatus of claim 1, wherein the first sensing area is disposed on a first surface of the glucose sensor and the second sensing area is disposed on a second surface of the glucose sensor. 13. The apparatus of claim 12, wherein the first surface and the second surface are co-planar. 14. The apparatus of claim 12, wherein the first surface and the second surface are on opposing sides of the glucose sensor. 15. The apparatus of claim 1, wherein the glucose sensor is configured to require no user calibration. 16. The apparatus of claim 1, wherein the glucose sensor is factory calibrated.
