An apparatus and method for determining an analyte concentration of a sample, such as a tissue sample. The apparatus may comprise an emitter, close proximity detectors laterally located less than about 2 mm away from the emitter, and far away detectors laterally located greater than about 0. 5 cm away from the emitter. A plurality of wavelengths may be sent from the emitter to the sample, reflected off of the sample, and received by the detectors. The reflectance value measured by the close proximity detectors may be used to calculate one or more scattering coefficients. The reflectance value measured by the far away detectors may be compared with a reflectance value calculated using the scattering coefficients in a numerical inversion of a diffusion model to determine the analyte concentration of the sample.

An implantable system includes light sources to transmit toward vascularized tissue, in a time multiplexed manner, light having a first wavelength of approximately 660 nm, light having a second wavelength of approximately 810 nm, light having a third wavelength of approximately 910 nm, and light having a fourth wavelength of approximately 980 nm. The system includes one or more light detector to detect light of the first, second, third and fourth wavelengths scattered by vascularized tissue. Additionally, one or more processor is configured to determine levels of blood oxygen saturation based on the detected scattered light of the first and third wavelengths, determine levels of tissue oxygen saturation based on the detected scattered light of the first and third wavelengths, determine levels of hemoglobin concentration based on the detected scattered light of the second wavelength, and determine levels of tissue hydration based on the detected scattered light of the second and fourth wavelengths.
