Cellphone-based tech could cut lab visits for blood tests
New York: Researchers have developed a cellphone-based blood test technology that can provide immediate results in the comfort of one's home or a doctor's clinic, thereby cutting visits to the laboratory.
In a paper published in the journal Biosensors and Bioelectronics, the researchers detailed a mobile version of the "Enzyme Linked Immunosorbent Assay" (ELISA), the gold standard technique used to detect the presence of an antibody or antigen.
"ELISA is an important technology for biochemical analysis of proteins and hormones and is critical for the diagnosis of many diseases, such as HIV and Lyme Disease," said corresponding author Anna Pyayt, Assistant Professor at the University of South Florida in Tampa, US.
"But the machines required for the incubation and reading are expensive and bulky," Pyayt said.
Instead of sending patients to a laboratory, the new cellphone-based technology - Mobile Enzyme Linked Immunosorbent Assay (MELISA) -- allows for the very same test to be conducted in the doctor's office, clinic or even in a remote area.
"The MELISA allows patients to undergo testing and obtain results at point-of-care," Pyayt said.
The device accurately measures progesterone levels, a key hormone that impacts female fertility and is indicative of some cancers.
It consists of a water bath heater that incubates samples at a target temperature and analyses them via images taken by mobile phone.
The device uses colour analysis to determine the RGB (red, green, blue) colour components of each sample.
The blue colour component is used for further analysis due to its sensitivity to the changes in progesterone concentration.
"It is designed to make biomedical testing simple and affordable. When low cost testing can be integrated with routine clinic visits, this would greatly improve the quality of healthcare and detect worrisome signs earlier," Pyayt added.
The portable MELISA weighs less than half a kg, and the researchers believe that it has the potential help older patients suffering chronic conditions and those across the world.

MP CM Yadav announces credit cards, financial aid for cow keepers
Bhopal, Nov 2: The Madhya Pradesh government will provide credit cards to those rearing cows and their progeny, similar to those available to farmers, to help manage the upkeep of cattle, Chief Minister Mohan Yadav announced on Saturday.
“Along with the people growing crops, credit cards will also be made available to those rearing cows and their progeny to enable them to manage expenses on their care,” Yadav said during the state-level ‘Govardhan Puja’ ceremony at Ravindra Bhawan here.
He said that people who care for more than 10 cows will be given special financial aid, adding that the state government will invest and make arrangements for rearing 5,000 to 10,000 cows under the limits of municipal Corporations.
He said that people found guilty of slaughtering cows in MP will get seven years of imprisonment.
Earlier, he took part in the Govardhan Puja at his official house.
Later in Gwalior, where he attended two such events, Yadav said the state would protect the cow and its offspring.
Ministers and MLAs across the state also participated in Govardhan Puja.
Before holding this function at the state level, the BJP government in MP had organised ‘Shastra Puja’ (worshipping of weapons) on Dussehra in a similar manner, with the CM, his ministers and MLAs across the state joining in.
