A simple, miniaturized, disposable acquisition and test module for monitoring glucose or other analytes successively for multiple times is described. The apparatus is designed to collect and test small volumes of blood in a single step. Many samples can be acquired and analyzed using a single disposable sampling module, minimizing the number of disposables and improving ease of use of the system.

The invention claimed is: 1. An apparatus for collecting blood from a patient's skin, the apparatus comprising a disc shaped sampling module radially partitioned into a plurality of sampling segments positioned near a periphery of the disc shaped sampling module, each sampling segment having components to perform a single blood sampling and testing event and including a sampling port, a lancet having a tip, the tip adjacent the sampling port, the lancet maintained within a housing and operable to extend the lancet tip through the sampling port to pierce the patient's skin positioned adjacent the sampling port, the disc shaped sampling module having a plurality of sample test chambers, each of a sample test chamber in fluid communication with a sampling port via a capillary channel with a diameter that is less than 0.1 mm, the sample test chambers associated with testing means, each of a sample test chamber being sized to hold no more than about 0.4 microliter of a blood sample; a driver configured to be coupled to the lancet, the driver being associated with a driver port; a first seal that seals each of a lancet tip prior to use; a second seal adjacent to a lancet head that seals the driver port; a contact interface that aligns the sampling module with a reader device; and a rotation device coupled to the sampling module and configured to rotate the sampling module into position for a new sampling event. 2. The apparatus of claim 1, wherein each sampling segment further comprises a sampling site contoured for positioning the patients' skin, the sampling site defining an opening contiguous with the sampling port. 3. The apparatus of claim 1, wherein the sampling module includes at least 10 sampling segments. 4. The apparatus of claim 1, wherein each sampling segment is configured to allow integrated lancing, collection, and testing. 5. The apparatus of claim 1, wherein the sample test chamber is smaller than about 0.6 mm long by 0.6 mm wide by 0.4 mm deep. 6. The apparatus of claim 1, wherein each sampling segment further comprises a calibrant reservoir in fluid communication with a calibration chamber, the calibration chamber associated with calibrant testing means. 7. A blood sampling system comprising the apparatus of claim 1, the blood sampling system further comprising a reader device associated with the apparatus of claim 1. 8. The blood sampling system of claim 7 configured to allow integrated lancing of the skin, collection of blood, testing of the blood, display of information about the blood, and advancement of the apparatus of claim 1 to bring another sampling segment online. 9. A method of collecting and testing a series of blood samples, the method comprising a) obtaining a disc shaped sampling module that is radially portioned into a plurality of sampling segments with sample test chambers, and a reader device, each sampling segment adapted to perform a single blood sampling cycle of lancing, collecting, communicating in fluid form, and testing of a blood sample, the sampling module coupled to a rotation device to rotate the sampling module into position for a new sampling event, each of a sample test chamber in fluid communication with a sampling port via a capillary channel with a diameter that is less than 0.1 mm, the sample test chambers associated with testing means, each of a sample test chamber being sized to hold no more than about 0.4 microliter of a blood sample, a driver configured to be coupled to the lancet, the driver being associated with a driver port; a first seal that seals each of a lancet tip prior to use a second seal adjacent to a lancet head that seals the driver port; a contact interface that aligns the sampling module with a reader device, b) coupling the sampling module to the reader device, c) initiating the blood sampling cycle, d) using the rotating device to rotate the sampling module and advancing the sampling module to bring another sampling segment online, e) repeating steps c) and d) until substantially all sampling segments on the sampling module have been used, and coupling the sampling module and reader device. 10. The method of claim 9, wherein steps c) and d) may be repeated at least 10 times before performing step f). 11. The method of claim 9, wherein each sampling segment is configured to allow integrated lancing, collection, and testing.
