Abstract: A low cost means for increasing measurement sensitivity in LED/IRED near-infrared instruments is disclosed which utilizes a current modification means (27) for modifying the driving current supplied to each IRED (5) as a function of the opacity of the particular sample being measured. The current modification means is part of the processing means and comprises means for measuring a signal level (8) for each IRED at an analog-to-digital converter (10). Based upon the signal level detected for each IRED, the current modification means modifies the current to each IRED to a value that is as high as possible without saturating the analog-to-digital converter. Thus, by modifying the driving current of each IRED to such a maximal value, the analytical instrument of the present invention provides high resolution without the use of expensive electronic circuitry. Also provided is a system for generating and storing an optical signature of a particular user, thus further insuring the accuracy of measurements taken by the instrument.

Abstract: An instrument (10) for near infrared interactance quantitative analysis measurements to improve accuracy and repeatability of the measured results. These objectives are achieved by placing a narrow bandpass optical filter (23) between near infrared emitting diode radiation sources (16, 16', 17, 17', 18 and 18') and a radiation transmission tube (12). The filter (23) allows for more distinct isolation of the desired wavelengths in the measurement to achieve improved accuracy and repeatability. The filters (23) also eliminate the time consuming task of sorting through several diodes in search of a particular diode (16, 16', 17, 17', 18 and 18') whose output wavelength band is centered at the desired wavelength.

Abstract: In a near infrared quantitative analysis instrument an initial sample (10) is measured (18, 24) for a plurality of characteristics which include the ambient temperature of the analysis instrument at the time of the reading, the temperature of the sample itself, the optical energy level of the sample, the moisture content of the sample, and the percent protein of the sample. These characteristics are stored in a computer (14, 22) to provide a series of comparison criteria. A subsequent sample (10) is then measured (18, 24) for the same characteristics as the initial sample. The initial and subsequent characteristics are compared (26). The subsequent sample is determined to be substantially identical to the initial sample for a given criterion if the subsequent sample's measurement for the corresponding characteristic is within a tolerance for that criterion. If the subsequent sample is judged to be substantially identical to the initial sample for all criteria, it is determined to be substantially identical to the initial sample.

Abstract: A procedure for verifying the accuracy of a non-invasive blood glucose measurement instrument (10) utilizes in vitro or invasive measurement instruments (100), the accuracy of which is independently verifiable. Several glucose readings are taken with each instrument at approximately the same times. The measurement data from the in vitro instrument (100) is transferred to the non-invasive instrument (10) where it is compared to the data regarding the non-invasive measurements. If the difference between the measurements of the respective instruments is within a preset range, the non-invasive instrument is permitted to be used for an additional period of time. However, if the difference is beyond an acceptable limit, then the non-invasive instrument is prevented from taking any additional measurements and must be serviced or repaired.

Abstract: Near-infrared quantitative analysis instruments (170) non-invasively measure blood glucose by analyzing near-infrared energy following interactance with venous or arterial blood, or transmission through a blood containing body part. A replaceable cartridge (195) stores data unique to an individual patient/user. The analysis instruments (170) are accurate and readily lend themselves to at-home testidiabetics. A method is also disclosed for easily and reliably custom calibrating near-infrared quantitative analysis instruments including obtaining a plurality of blood samples and blood glucose level measurements thereof at a predetermined time interval. These values are entered into the analysis instrument. Near-infrared optical measurements of the individual are simultaneously taken using the analysis instrument at another predetermined time interval. Calibration regression analysis is performed on the data to custom calibrate the analysis instrument which involves linearly interpolating the blood sample glucose measurements with the near-infrared optical recordings.
