An integrated device is for sampling and testing an analyte. The device generally includes a housing, a lancing device for sampling an analyte, a test strip for substantially capturing at least a portion of the analyte, and a display unit for displaying a result corresponding to the captured portion of the analyte. A method includes performing a single operation to sample an analyte, to capture the sampled analyte, to perform testing on the sampled analyte, and to display a result corresponding to the performed test. A method includes using an integrated sampling and testing device placing the device the device on a test site of a subject, such as a patient, and performing the single operation to obtain a test result. The sampling and testing of analytes may involve testing analytes in blood, such as the blood of a diabetic patient.
