已经通过脉冲光声技术在体外和体内测量了葡萄糖浓度。体外结果表明，可以以优于 0.1% 的准确度测量生理范围内的葡萄糖浓度 (30 - 600mg/dl)，相关性 R2 = 0.989。其他血液分析物在光声测量中的作用已得到探索，已对 8 名受试者进行体内测量，在葡萄糖浓度范围 80 - 640mg/dl 内，标准偏差在 ± 1.5% 至 ± 12% 之间，R2 = 0.959。
Glucose concentrations have been measured by the pulsed photoacoustic technique both in-vitro and in-vivo. The in- vitro results show that glucose concentrations in the physiological range (30 - 600mg/dl) can be measured with an accuracy of better than 0.1% with a correlation of R2 = 0.989. The role of other blood analytes in photoacoustic measurements have been explored, iη-vivo measurements on 8 subjects have been achieved with a standard deviation of between ± 1.5% and ± 12 % with an R2 = 0.959 over the glucose concentration range 80 - 640mg/dl.
