`
`to permit transmission of light along a plurality of varying path lengths.
`
`11. (Withdrawn) The method of claim 1, wherein the container volume is less than 100
`
`micro liters.
`
`12. (Withdrawn) The method of claim 1, wherein a plurality of distinct path lengths are imaged
`
`simultaneously.
`
`13. (Withdrawn) A method of measuring an analyte concentration in a sample fluid comprising:
`
`(a) providing the sample contained in a container dimensioned with a plurality of
`
`distinct widths to permit transmission of light along a plurality of varying path lengths
`
`that correspond to the plurality of distinct widths;
`
`(b)
`
`illuminating the container along at least one of the plurality of path lengths; and
`
`(c)
`
`imaging the container to measure a first light intensity transmitted across said at least
`
`one of the plurality of path lengths, for the determination of the concentration of the
`
`analyte based on the measured first light intensity.
`
`14. (Withdrawn) The method of claim 13, further comprising:
`
`(a)
`
`imaging the container to measure a second light intensity transmitted across another
`
`path length corresponding to another distinct width of the container;
`
`(b) comparing said first light intensity and the second light intensity;
`
`(c) determining an analyte concentration based on said comparing step.
`
`15. (Withdrawn) The method of claim 13, further comprising selecting a desired detection path
`
`length by one or more of the following: (a) moving a light source relative to the sample, (b)
`
`moving a detector relative to the sample, or (c) moving sample within the container relative
`
`to the light source.
`
`16. (Withdrawn) The method of claim 13, wherein the illumination is provided by a light source
`
`and the imaging is provided by a detector, wherein the light source and the detector are on
`
`opposing sides of the container.
`
`17. (Withdrawn) The method of claim 13, wherein the illumination is provided by a light source
`
`and the imaging is provided by a detector, wherein the light source and the detector are on
`
`the same side of the container.
`
`18. (Withdrawn) The method of claim 13, wherein the plurality of path lengths are orthogonal to
`
`the length of the container.
