This Diagnostic Lollipop Replaces Throat Swabs For Sweeter-Tasting Medical Exams

Collecting saliva samples for diagnostic testing, such as when throats are swabbed to test for strep throat, may soon undergo a delightful transformation.

That’s because scientists Sanitta Thongpang, Ashleigh Theberge, and Erwin Berthier from the University of Washington have developed a novel method that replaces the discomfort of throat swabs with a familiar childhood treat: lollipops.

This innovation, known as CandyCollect, offers a less invasive alternative for patients while delivering accurate results.

The CandyCollect device features a spoon-like end with a spiral-pattern groove, providing an ideal surface to collect saliva. To enhance the experience, the device is coated in a sweetened candy made from beet-derived sugar, allowing patients to simply lick it like a regular lollipop.

This approach offers a more pleasant experience, especially for young children or individuals with a fear of traditional swabs.

In tests, CandyCollect demonstrated its effectiveness by consistently detecting the presence of bacteria like Streptococcus mutans and Staphylococcus aureus.

The results obtained from CandyCollect aligned with those obtained through traditional test kits, ensuring reliability. Notably, this innovative method produced accurate results even at room temperature, further enhancing its practicality and convenience.

Could this sweet-tasting method have the potential to revolutionize how infections are detected and diagnosed? Possibly, and soon enough, the application of this technology may extend beyond strep throat, opening doors to less invasive testing for various infections.
