The spotlight was on OraSure Technologies(OSUR 0.57%) this summer, when the FDA approved its OraQuick HIV testing kit for in-home use. The test analyzes oral fluid as opposed to blood samples, requiring nothing more than a quick mouth-swab and less than a 30-minute wait time for results. Clinicians have used the kit for years, but as of July it was approved for consumer purchase as well.

OraSure is launching the kit this month, and investors should be closely watching the product's sales in upcoming quarters. Health-care analysts Brenton Flynn and Max Macaluso discuss this catalyst.
