New Medical Device That Can Diagnose Infections Faster

Time is so precious. It may be a matter of 1 second but it cannot be taken back. When it comes to diagnosing or identifying a disease that the patient is facing and treating it accordingly so that the virus will not spread to other persons and can even contribute to the development of drug-resistant bacteria. When a patient arrives at a hospital with a serious infection or any health problem, doctors have precious few minutes to make an accurate diagnosis. Doctors’ ability to act quickly and correctly which not only makes a difference to the patient’s health position, it determines whether the infection spreads to other patients in the clinic.

Now it’s a time to shift to a new device which helps the doctors to identify the illness of the patient by diagnostic device created by collaborative team of UA engineers and scientists may help.

New Medical Device That Can Diagnose Infections Faster

The device’s novel approach to molecular diagnostics, called DOTS qPCR, is faster, more efficient and less expensive than alternatives currently being used by doctors in their clinics.

Dustin Harshman, a former graduate student in the Biomedical Engineering Graduate Interdisciplinary Program, currently a scientist at Ventana Medical Systems says “We have developed a completely different type of system than what exists out on the market, we want to see physicians get diagnostic information more rapidly and prescribe better initial therapies. What’s interesting about the way we approached this is that we’ve developed a deep understanding of what’s happening at a molecular level in our system. That kind of understanding gave us the ability to figure out why it was failing, and then leverage that failure as an advantage to create a completely new method.We’re envisioning a device that will provide physicians with answers as soon as they perform a biopsy, while they’re still sitting with the patient. By saving diagnosis time, we can decrease complications for patients, isolate infections to prevent spreading, and avoid creating selective pressure for antibiotic-resistant bacteria, which is a huge burden on the medical system.”

“With DOTS qPCR we are able to detect amplification and identify the infection after as few as 4 thermal cycles, while other methods are working with between 18 and 30, we can get from sample to answer in as little as 3 minutes and 30 seconds. It’s easy to use, smartphone-integrated and saves money and labor using expensive equipment. This technology has a lot of commercial potential, and we’d be happy to work with industry to bring it to market.” said Jeong-Yeol Yoon, a professor in the Department of Agricultural and Biosystems Engineering and a joint appointment in the Department of Biomedical Engineering.
