Summary "Non-Invasive Blood Testing" The present invention provides a personal portable monitor (phhm) comprising a signal acquisition device for acquisition signals that can be used to derive a measurement of a user's health-related parameter. wherein the signal acquisition device comprises a blood photosensor having one or more photo-emitters for transmitting light to a user's body part, one or more photodetectors for detecting light transmitted through or scattered by at least one of which contains an analyte to be detected or mimics the absorption spectrum of the analyte, through which light has been or will be transmitted through or dispersed by the passing body part reach the photodetector, wherein the phhm processor is adapted to process the signals received from or each photodetector to calculate the difference intensity in light passing through or each analyte cell and light passing through or each non-analyte cell to determine the user's pulse and to correlate the signals obtained from the photosensor with the user's pulse, where the phhm is adapted to apply pressure to the body part or to have pressure applied to it by the body part, so that, in use, an artery in the body part changes from occluded to unobstructed during each pulse and phhm is adapted to derive a measurement of the change in the luminal area of the artery during each pulse and to correlate the signals received from the blood photosensor with the pulse and the change in the luminal area of the artery to provide a measurement of the analyte concentration in the blood. arterialresumo “análises de sangue não-invasivas” a presente invenção proporciona um monitor portátil pessoal (phhm) que compreende um dispositivo de aquisição de sinal para os sinais de aquisição que podem ser utilizados para derivar uma medição de um parâmetro relacionado com a saúde do usuário, em que o dispositivo de aquisição de sinal compreende um fotos-sensor de sangue tendo um ou mais foto-emissores para transmissão de
