SYSTEM AND METHOD FOR DETERMINING BLOOD DISORDERS FOR A BLOOD TYPE USING PPG TECHNOLOGY

Abstract:

A biosensor obtains at least a first photoplethysmography (PPG) signal at a first wavelength from a user and a second PPG signal obtained at a second wavelength from the user. The biosensor determines a first R value of the user using the first PPG signal and the second PPG signal and compares the first R value of the user to a normal range of R values for a blood type of the user. The biosensor determines a color of blood of the user using the first, second or another PPG signal and determines an abnormal condition that affects red blood cells of the user in response to the color of the blood and/or in response to the comparison or the first R value of the user to a normal range of R values for a blood type of the user.
