Biosensor system for accurate analyte concentration determination
A biosensor system for determining analyte concentration in a sample has been granted a patent (Publication Number: US11988626B2). The system includes a test sensor with a sample interface, a temperature sensor, and a reservoir. The method involves generating and transmitting an electrical input signal, applying it to the sample, measuring the analytic output signal, and determining the analyte concentration based on temperature, primary compensation, first residual compensation, and the analytic output signal. The primary compensation aims to compensate at least 50% of the total error in the analytic output signal, while the first residual compensation targets at least 5% of the total error.
Furthermore, the biosensor system can be portable and includes features such as supplying temperature and hematocrit value to the primary compensation, converting the analytic output signal with a conversion function, adjusting the first residual compensation with a weighing coefficient, and conducting a second residual compensation. The system also accounts for error arising from operating conditions and multiple fillings of the reservoir with the sample. The method involves exclusion tests for potential error parameters and determining the compensated analytic output signal based on primary, first residual, and second residual compensations. Overall, the patented biosensor system offers a comprehensive approach to accurately determine analyte concentration in samples by addressing various sources of error and implementing compensation strategies to enhance the reliability of the results.
