It is highly recommended you have a routine screening test for STI/STDs each year if you are sexually active. This is to rule out any STI/STDs that do not show any symptoms, as you may not be aware that you have contracted an STI/STD without a test being completed. STI/STD testing offers the ability to find an infection early on, due to this you can get treatment for it and prevent the spread of the infection to others. If you leave an STI/STD untreated, it can lead to serious complications. If you or your partner's STI/STD test shows up positive, you or your partner will need to also get a test completed to make sure they can get the treatment needed if they also contracted an STI/STD. Some STI/STDs can be cured with treatment, while others cannot. However, most STI/STDs can receive treatment to help with any symptoms.
