RE:RE:RE:Rapid Antigen TestsTheeRook wrote: The device is an armband with embedded light sensors and a small computer processor. The armband is wrapped around a person’s bare left arm above the elbow during use. The sensors first obtain pulsatile signals from blood flow over a period of three to five minutes. Once the measurement is completed, the processor extracts some key features of the pulsatile signals, such as pulse rate, and feeds them into a probabilistic machine learning model that has been trained to make predictions on whether the individual is showing certain signals, such as hypercoagulation in blood. Hypercoagulation is known to be a common abnormality in COVID-19 patients. The result is provided in the form of different colored lights used to indicate if an individual is demonstrating certain biomarkers, or if the result is inconclusive.
Any idea what kind of sensitivity/specificity numbers it has?
The tech I see as a future option is a breathalyzer unit a couple of groups are working on, results in a minute or two, but last I heard they were working on getting the numbers up to a more reliable level. Still need a plastic mouthpiece for each person but maybe they can be sterilized to prevent garbage mountains.
