[CNN] - The US Food and Drug Administration authorized the first at-home over-the-counter test for syphilis Friday.

Until now, people who suspected that they had the sexually transmitted infection had to go to a doctor to get tested. With the new test from the biotech company NOWDiagnostics, it will take the user just 15 minutes and a single drop of blood to determine whether they have syphilis.  

The company said the test will be available in the second half of 2024 and is expected to cost $29.98.

The new test received FDA authorization after the company submitted data from clinical trials showing that the First To Know Syphilis Test identified a positive specimen 93.4% of the time. The trials also showed that it was easy for people without medical training to use the test.
