20230108045 · 2023-04-06 ·

The present disclosure relates to systems and methods for measuring glycated A1c hemoglobin. A glycated hemoglobin level measuring system includes a sample testing apparatus having a microchannel that compresses a blood sample traveling through, a first pair of electrodes coupled to the microchannel, and a second pair of electrodes coupled to the microchannel. The glycated hemoglobin level measuring system further includes an analysis apparatus having sensors coupled to the first and second pairs of electrodes and configured to calculate a travel time taken by a red blood cell to pass through the first and second pairs of electrodes. The glycated hemoglobin level measuring system can use the travel time to measure a rigidity of the red blood cells and the corresponding glycated hemoglobin level.

Self calibrating blood chamber

An optical blood monitoring system and corresponding method avoid the need to obtain a precise intensity value of the light impinging upon the measured blood layer during the analysis. The system is operated to determine at least two optical measurements through blood layers of different thickness but otherwise substantially identical systems. Due to the equivalence of the systems, the two measurements can be compared so that the bulk extinction coefficient of the blood can be calculated based only on the known blood layer thicknesses and the two measurements. Reliable measurements of various blood parameters can thereby be determined without certain calibration steps.
