The only inexpensive , rapid blood test currently available for an STIs is for syphilis. This test is already in use in some resource-limited settings. The test is accurate, can provide results in 15 to 20 minutes, and is easy to use with minimal training. Rapid syphilis tests have been shown to increase the number of pregnant women tested for syphilis. However, increased efforts are still needed in most low-and middle-income countries to ensure that all pregnant women receive a syphilis test.
