Original Paper


Nowadays, large number of anaemia cases can be seen especially in women and children. It is caused due to low haemoglobin level in blood. Mostly conventional methods are used to calculate haemoglobin level. These methods involve pricking of human body with needle and sending blood sample to laboratory for further analysis which results in delay and chances of infection increases. This research work is aimed at designing a instantaneous non invasive small, portable and low cost device to determine hemoglobin value in blood which makes it completely mobile. The prototype is based on transmittance type PPG sensor having LEDs and photo detector. The developed prototype capability for hemoglobin detection is validated on 8 subjects by comparing its results with laboratory type digital calorimeter. As a result, the response of prototype has been proved with mean absolute error of 0.7 having a small bias of 0.1 g/deci litre (g/dl) with all data points lie within 95% limits. This shows good agreement and perfect correlation between developed prototype and standard instrument.
