Amid a potential shortage of nasal swabs to collect samples for coronavirus testing, researchers have come up with an alternative: 3D-printed nasal swabs.
A clinical trial has provided evidence that 3D-printed alternative nasal swabs work as well, and safely, as the standard commercial nasal swabs.
The only adverse reaction was a few instances of slight nasal bleeding. The cost of materials per 3D-printed nasal swab ranges from 26 to 46 cents; commercial swabs cost about $1 each.
