Researchers from IIT-KGP have developed a low-cost diagnostic device which can test a blood sample taken from the finger prick. A statement from IIT-KGP said “the device requires only a paper strip based kit integrated with a smart phone to enable analytics and readout functions and an LED light for imaging”.
The main aspect of the kit is its operational simplicity and extreme low-costs. The kit has been developed by a research team led by Professor Suman Chakraborty. Under the laboratory condition the test will cost only Re 1 or even less, the may increase marginally in case of commercialization of the product, the statement further added.
Operating the device is very simple as it requires a single drop of blood and a drop of reagent on the paper-based reaction chamber. The detection method is designed to harness the flow of blood from an input source pad to a reaction pad for the diagnosis.
"Compared to other reported portable devices for hemoglobin estimation, this device is implementable without any trained personnel at resource-limited settings, Ms Chakraborty said.
Extensive validation testing has been done for blood glucose and hemoglobin at the laboratories as well as in the field (both clinical environment and villages with limited clinical facilities).
"We have tested it at extreme challenging environment with uncontrolled dirt, dust and humidity, and in the absence of structured clinics or air-conditioned pathological laboratories to work," Dr Satadal Saha, visiting professor at the School of Medical Science and Technology of IIT Kharagpur, said.
