IIT Kharagpur Team Devises One-Rupee Test to Measure Haemogl
A new device created with a novel fabrication technique is expected to be able to measure haemoglobin levels from a small quantity of blood and with the help of a smartphone app.

According to a study published earlier this year, 4.1% of the Indian population – about 50 million people – was in a state of “hidden poverty due to medical expenses” in 2011.

In a country where affordability deters access to healthcare, there is an urgent need to develop high-quality, easy-to-use, scalable and affordable technologies that solve problems in screening, diagnostics and therapy. These solutions will have to be devised by people at the primary healthcare level because secondary and tertiary care are more expensive.

Researchers at IIT Kharagpur recently pitched one such solution.

India bears one of the world’s biggest national burdens of anaemia. According to the 2018 Global Nutrition Report, almost 52% of women of reproductive age but who weren’t pregnant and 50% of pregnant women were anaemic. Anaemia precipitates organ damage by lowering the amount of oxygen in the body and contributes to multiple problems during pregnancy. These then culminate in pre- and post-natal maternal mortality.

Suman Chakraborty, a member of the department of mechanical engineering at IIT Kharagpur and the dean of sponsored research and industrial consultancy, and his students have attempted to build a low-cost, minimally invasive and portable device to measure haemoglobin levels.

Through a series of chemical reactions, haemoglobin helps break down hydrogen peroxide to produce oxygen. According to its design, the device triggers just these reasons to produce oxygen, which is made to react with o-toluidine to produce a bluish-green substance. This substance absorbs light proportionally to its amount, so the more there is, the darker it will appear. Using this indicator, its makers say the device can estimate the amount of haemoglobin in the blood.

While this technique is not new to biochemistry, the device’s makers say its fabrication is novel. “We have printed micro-channels on a filter paper using a simple office printer, which guides the collected blood sample to pre-designated reaction chambers containing the reagents,” Chakraborty said.
