Researchers in India have created a cheap blood testing kit from a Raspberry Pi 4, using light and an automated fluid dispenser to help analyze any biochemical substances in the blood sample. The work, by Sangeeta Palekar and Jayu Kalambe of Shri Ramdeobaba College of Engineering and Management, has been published in the journal IEEE Sensors and reported by IEEE Spectrum.
Blood tests in India are mostly carried out near more highly populated areas, where they can be analyzed in a laboratory. The new mobile kits produce results consistent with those from the lab, do their work in half a minute, and allow blood testing to be rolled out to the country’s vast rural areas.
