A method and apparatus using photo-stimulation to treat or pretreat a sample site prior to analyte concentration determination is presented. More particularly, photo-stimulation at or near at least one sample site is used to enhance perfusion of the sample site leading to reduced errors associated with sampling. Increased perfusion of the sample site leads to increased volume percentages of the target analyte and / or allows the blood or tissue constituent concentrations to more accurately and / or precisely track corresponding sample constituents in more well perfused body compartments or sites such as arteries, veins, or fingertips. In one embodiment, analysis of the photo-stimulated site is used in conjunction with glucose analyzers to determine the analyte concentration with greater ease, accuracy, or precision and may allow determination of the analyte concentration of another non-sampled body part or compartment.
