Now a winner of the XPRIZE Rapid Covid Testing Competition’s “Open Innovation” track, RAM Global’s groundbreaking Diagnostic Platform, ThEA, identifies pathogens, including SARS-Cov-2, via direct, electronic detection, without the need for costly, hard-to-supply chemical reagents.

ThEA is on track for commercial release in 2021.
The result of a wholly different approach to diagnostics, the Terahertz Express Analyzer, or simply, ThEA, employs RAM Global’s next-generation sensor technology to deliver a groundbreaking solution to the challenges of accurately identifying pathogens, including SARS-Cov-2. ThEA uses terahertz frequencies to detect a pathogen’s genetic frequency signature – the energy release pattern unique to each type of biomolecule. It requires no expensive chemical reagents, no cumbersome transportation of samples, and no specialized laboratories. Instead, patients can, either volunteer a throat swab or simply breathe into one of our proprietary “breathalyzers,” and they’ll have an accurate result a few moments later.
The platform represents the first application of semiconductor science to SARS-Cov-2 testing and offers a cloud-connected diagnostic that yields an accurate analysis at the point of use and provides secure, sharable data – all in less than 2 minutes. With ThEA, patients can know within mere moments whether they should seek care and temporary isolation, or if it is safe for them to go about their lives. And because ThEA is completely portable, it can be stationed at transportation hubs, in commercial centers, or anywhere else people need to gather, to provide a rapid, accurate, cost-effective means of protecting the public space and preserving public health.

Read about how RAM Global was awarded XPRIZE in Germany in developing faster, cheaper, and easier to use COVID-19 testing methods.

RAM Global’s Terahertz Express Analyzer Sensing Platform, aka ThEA, can diagnose viral infections at point of care—including coronavirus—in less than 2 minutes, with high sensitivity and at a fraction of the cost of other tests.
Our ThEA Platform is biochemical free—it’s contactless, portable, completely digital, and extremely user-friendly. With a ThEA readout system, anyone can test for any virus anywhere.
The sooner we detect a viral infection, the sooner we can take care of patients and prevent the spread to others. The best way to do that is with a quick, reliable test. The ThEA Platform will provide fast, accurate results even before a patient exhibits symptoms of infection. With widespread use, the ThEA Platform can help curb rapid spread of disease and help ensure better care by easing pressure on our overburdened health care system.
Conventional biochemical tests for viral infection have limitations. For starters, the sample has to have a high level of the virus and the antibodies that the body’s immune system makes to fight the virus, in order to trigger a positive result. This means you can have the virus for days before these tests can detect it. Plus, they’re expensive and take hours–sometimes days–to deliver results. They also require specialized labs to be processed. And, because the process is biochemical in nature, it is subject to environmental factors that can contribute to a high percentage of false negative or false positive results. In fact, many commonly used SARS-Cov-2 testing platforms achieve sensitivities of less than 80%, even when there is a low CT value.
Other testing options available, such as X-ray and CT Scans are more sensitive than biochemical tests, but there are far fewer of them available and they are even more expensive. They still require the disease to be fairly far along in order to detect it.
To help solve this problem, we decided to take our proprietary Terahertz Express Analyzer Sensing technology and next-generation sensors and apply them to a diagnostic platform.
Because our process is digital, it requires no labs, no chemicals, and gives no chance for transport or environmental factors, such as temperature change, to affect the process. Altogether, that adds up to a high sensitivity rate. In fact, the platform is so sensitive, it can tell the difference between different strains of the same virus, giving healthcare workers vital insights into virus mutations.
Our system is comprised of two parts: first, the ThEA portable readout system—a user-friendly, cloud-connected interface—and second, a test kit that holds a patient sample, such as a simple throat swab. Insert the kit into the ThEA and in less than 2 minutes, you’ll know if a patient is infected or virus free. Because the kit is housed in an industry standard, eco-conscious plastic case, it’s very affordable and easy to manufacture and distribute. And because the kit is single use, it’s very sanitary.
The ThEA portable readout system itself, however, will become a permanent addition to the healthcare provider’s infrastructure. The ThEA platform can be used thousands of times to diagnose any number of pathogens, including COVID-19 coronavirus. When deployed at scale, the highly-portable ThEA Platform and test kits can be used to rapidly screen people during a viral outbreak – quickly differentiating between patients who need to be treated and persons who are safe to go about their day. Its versatility makes it an ideal asset for medical professionals in situations ranging from the common to the extraordinary.
The ThEA Platform automatically backs up information to a cloud-connected database that can be shared by healthcare providers, agencies, local, state, and federal authorities. This digitalization could make it easier than ever to track the progress of an outbreak, eliminate redundant testing, and to create “exposure trees” that detail who the patients have interacted with since their infection. Armed with this knowledge, health officials could quickly ascertain who else needs to be tested, who should be treated or isolated, and who can safely continue their normal activities. This could help greatly reduce the need for a societal shutdown in the case of future pandemics.

How ThEA Works
Everything gives off a unique energy, even viruses. This energy is a frequency wave that goes up and down a certain number of times per second. Think of it as a sort of hum. This energy release is measured in hertz. One hertz equals one cycle in a second – a single peak in the energy wave. One kilohertz is a thousand cycles in a second. That’s one thousand peaks, and one thousand troughs, or gaps in between peaks. One terahertz is one trillion cycles in a second.
It turns out that proteins and genetic material like DNA and RNA, which viruses produce, have a special reaction to terahertz frequencies. These proteins and genetic material emit energy that has a uniquely strong and specific reaction to terahertz frequencies.
They actually bind to the miniscule structures that form the microscopic gaps in between each wave in the terahertz cycle. Specific proteins and genetic materials respond to specific frequencies in the 1 to 2 terahertz range.
The ThEA Platform uses specially designed glass to create resonances at specific points in the 1 to 2 terahertz range. By tuning the device to specific points along this spectrum, the platform can attract the exact genetic material that responds only to that unique frequency. Once the genetic material is found in the gap, the ThEA Platform alerts the practitioner by signaling a positive result. If the frequency does not attract the specific protein, DNA, or RNA that it is “calling” for, then it signals the absence of that genetic material by giving a negative result.
This process requires no chemical re-agents, such as substances added to the body fluid samples for the purpose of diagnostics. By eliminating this cumbersome step, the chances of error due to environmental factors (such as temperature) are drastically reduced, and true portability becomes possible. In normal times, this is a huge convenience, not to mention a massive cost saver. But in times of mass viral outbreak, this can be the difference between life and death.
