In clinical trials, the accuracy of self-testing with Teal’s wand matched that of a cancer screening performed in a doctor’s office.

The startup’s test, Teal Wand, detects human papillomavirus (HPV), which is responsible for nearly all cervical cancers, similar to Roche’s cobas HPV test. But Teal Wand allows women to collect samples from home and send it to a certified lab for testing, while Roche’s test is approved for use in the clinic.
