Researchers at Washington State University have developed a <\/span>low-cost, pocket-sized laboratory<\/span><\/a> that works nearly as well as clinical laboratories to detect common viral and bacterial infections. <\/span><\/p>\n

\u201cThis smartphone reader has the potential to improve access and speed up healthcare delivery,\u201d <\/span>Lei Li<\/span><\/a>, assistant professor in the <\/span>School of Mechanical and Materials Engineering<\/span><\/a> at WSU and lead author of the study<\/span>, <\/span>said in a statement. \u201cIf we find out about infections, we can treat them more quickly, which makes a difference especially in low-resource, remote areas.\u201d<\/span><\/p>\n

The WSU team collaborated with the <\/span>University of Pennsylvania\u2019s Perelman School of Medicine<\/span>. <\/span><\/p>\n

Their paper is published in the journal <\/span>Clinica Chimica Acta<\/span><\/a>. <\/span><\/p>\n

The best guess scenario<\/b><\/h2>\n

Across the country, doctors in underserved areas lack the resources they need to determine whether a patient has an infection or not. <\/span><\/p>\n

They are sometimes forced to rely on a patient\u2019s symptoms or take their best guess by looking at test sample color results, leading to inaccurate results. <\/span><\/p>\n

Unfortunately, if they send the results to a lab in a distant city that has the appropriate testing resources, they then have to wait for a diagnosis, which often come days later. By that time, the infection may have already spread and becomes harder to contain. <\/span><\/p>\n

Mobile health diagnostic devices exist, but their usefulness is limited in that they can only analyze one sample at a time. <\/span><\/p>\n

However, now with the new portable reader, doctors in underserved areas can simply pull out their phones to accurately test the infection and treat patients accordingly. <\/span><\/p>\n

The team\u2019s motive was to \u201c<\/span>turn smartphone into something more than just making a call or taking a picture,\u201d said <\/span>Lei Li<\/span><\/a>, assistant professor in the <\/span>School of Mechanical and Materials Engineering<\/span><\/a> at WSU and lead author of the study<\/span>. \u201cSmartphone is a powerful tool and it can help us in many other ways.\u201d<\/span><\/p>\n

The pocket-sized lab<\/b><\/h2>\n

The researchers proved that their portable reader, a little bigger than a smartphone, worked nearly as well as standard lab testing in detecting 12 common viral and bacterial infectious diseases, such as mumps, measles, herpes and Lyme Disease. <\/span><\/p>\n

With a smartphone simply placed on top, the device takes a photo of 96 sample wells at once and uses a computer program to carefully analyze color to determine positive or negative results. <\/span><\/p>\n

The researchers tested the device on 771 patient samples at the Hospital of University of Pennsylvania and found that the results were accurate 97 to 99.99 percent of the times. <\/span><\/p>\n

The researchers were able to build the device for about $50. But, according to Li, the manufacturing cost would probably be lower than that. <\/span><\/p>\n

The Next Step <\/b><\/h2>\n

The team has filed a patent, and hopes to move forward with clinical trials. Their intent is to ultimately make the device available on the market.<\/span><\/p>\n

The researchers believe their device will bring faster and lower-cost lab results for fast-moving viral and bacterial epidemics, especially in rural or lower-resource regions where laboratory equipment and medical personnel are sometimes not readily available. <\/span><\/p>\n

\u201cUnderserved areas can conduct the same quality tests with much less cost and time by using these kind of smartphone devices,\u201d said Li. <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
