A new at-home HIV test, called OraQuick, has been approved by the Food and Drug Administration. It uses a cheek swab and yields results in 20 to 40 minutes. Orasure plans to start selling the test in October, both online and through retailers like Walgreens, CVS and Walmart. Spring this on your new mate just before telling him/her about the 90-day rule. It’s recommended that people who test negative should re-test after three months, because it can take several weeks for detectable antibodies of HIV to appear.
