Abstract:
A biosensor identifies a blood type using photoplethysmography (PPG) technology. A PPG circuit obtains a plurality of spectral responses at a plurality of wavelengths detected from skin of a user. A processing circuit determines a blood factor indicator using the plurality of spectral responses. The blood factor indicator may include a signal quality parameter or a ratio R value. A calibration database includes a correlation of the blood factor indicator to a plurality of blood types. The blood blood type of the user is identified using the blood factor indicator and the calibration database.

Claim (Index 21):
The biosensor of  claim 18 , wherein the processing circuit is further configured to:\n determine an absorption spectra shift using a third spectral response and a fourth spectral response of the plurality of spectral responses; access the calibration database, wherein the calibration database includes a plurality of calibrations that associate the absorption spectra shift to the patient vital for the plurality of specific blood types; and obtain the patient vital of the user using the absorption spectra shift, the calibration database and the blood type of the user.
