Hunt is on for more accurate in-home antigen testing

Detect involves a bit more pouring of liquids by the customer, with a lower-tech approach that relies on enzymes, not electronics, to create that amplification reaction. It has an app but no Bluetooth, and results come to cellphones in about an hour. Cue’s method, by contrast, draws on electrochemistry to create what it basically a miniature PCR machine, produced at its large Southern California warehouse.
