QuestDirect is the best STD test for pregnant women. The self-collection kits have tests that pregnant women can use to test different types of sexually transmitted infections. If you are close to one of their service centers, you can go for in-person testing. But most people prefer the home kits because they are more private. After you are done, you can return the kit to the labs using the prepaid, addressed packaging. Your results will be available in a free yet secure portal, MyQuest.
