Summary:
Researchers at the University College London and the University of Ghana have developed a smartphone-based system to detect haemoglobin concentrations.
Anaemia is a common disease that affects over two billion people globally and causes reduced oxygen-carrying capacity.
Smartphone colourimetry has proven to be a useful tool in making anaemia screening more widely available, especially in low- and middle-income countries. The technology uses a phone camera to take images of body parts with little pigmentation, and the app analyses the colour of the imaged tissue using absorbance analysis techniques to determine haemoglobin concentrations.
Clinical trials are needed before it can be adopted in low- and middle-income countries, but the results are highly promising, with the app achieving a sensitivity score of 92.9% and specificity of 89.7%.
