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.

Kerala HC declines interim stay on screening of ''L2: Empuraan''
Kochi (PTI): The Kerala High Court on Tuesday declined to issue any interim order putting on hold the screening of Malayalam film 'L2: Empuraan' starring superstar Mohanlal.
Justice C S Dias ordered to issue notice to the Centre and the Censor Board seeking their stand on the plea by Thrissur-native V V Vijeesh who has claimed that continuing to show the movie poses a risk of inciting communal violence and disturbing public order.
It listed the matter for hearing after the vacation.
The court also questioned whether the petition was filed in publicity interest by the petitioner.
During the brief hearing of the matter, the court also asked what was the problem when the Censor Board had certified the film for public viewing.
It also expressed doubts about the petitioner's intention behind filing the plea.
It also pointed out that no case was filed anywhere against the movie.
The state government said that no case has been lodged against the film in Kerala.
Meanwhile, Antony Perumbavoor, one of the producers of the film, earlier in the day announced that the movie has undergone cuts to remove scenes of little over two minutes.
He said the decision to carry out the edit was a joint one of all the producers and actors, including Mohanlal and Prithviraj Sukumaran, and it was not out of fear of anyone.
The movie has faced intense criticism from the Sangh Parivar with regard to some portions of the film.
'L2: Empuraan', the second part of the 'Lucifer' movie, a trilogy planned by the Prithviraj-Mohanlal team, has become a topic of hot debate over its critique of right-wing politics and the covert mention of the Gujarat riots.
On March 27, the day of the movie's release, the Sangh Parivar vehemently criticised the film on social media, while the Congress and Left platforms celebrated the film for portraying the right-wing politics as "villainous".
