Abstract
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.
