The invention comprises a method and apparatus for selecting optical pathways sampling a common tissue position, such as a lateral mean range in the dermis, of a person for analysis in a noninvasive analyte property determination system, comprising the steps of: probing skin with a range of illumination zone-to-detection zone distances with at least two wavelength ranges, which optionally overlap, and selecting, using a metric, illumination zone-to-detection zone distances having mean optical pathways probing the common tissue layer, such as without the mean optical pathways entering the subcutaneous fat layer of the person. Optionally, the skin tissue layers are modulated and/or treated via tissue displacement before and/or during data collection.

Sample position resolved noninvasive glucose concentration determination analyzer apparatus and method of use thereof

The invention comprises a method and apparatus for sampling a common tissue volume and/or a common skin layer skin of a person as a part of noninvasively determining an analyte property with an analyzer including: a set of detectors at least partially embedded in a probe housing, the probe housing comprising a sample side surface, the detectors including a first and second range of detection zones of differing radial distances from a first illumination zone and second illumination zone, respectively coupled to separate sources, with surface paths between the sources and detectors overlapping a common skin area during use.
