Are std tests accurate?

The tests may yield false positive results, showing the presence of an infection where there is none. A more serious possibility is a false negative result, in which there is an infection but it is not detected. However, tests performed on samples that you collect yourself may not always be accurate. If the result of a home test for an STI is positive, contact your healthcare provider or a public health clinic to confirm the test results.

If your home test results are negative but you have symptoms, contact your provider or a public health clinic to confirm the results. One of the reasons why false negatives occur is due to tests performed before the recommended testing period. No STI test is accurate immediately after having sex, because the bacteria or virus takes time to reach a detectable state or until the body has an immune response. If the initial test was performed during the first 12 weeks after possible exposure, the test should be repeated after an additional 12 weeks for more reliable results.

For example, if a person has been tested for chlamydia and the result is negative, but then it turns out that the person has chlamydia, it would be a “false negative”. Urine or swab tests (NAAT) are very sensitive and also specific for the detection of trichomonads, so, as mentioned above, it is suggested to test trichomonads at the same time as gonorrhea and chlamydia (2 weeks after possible exposure). There are several different types of STD tests that work in slightly different ways, whether they are from a different type of sample or from a different manufacturer. Sexually transmitted diseases are common, but the types of STI tests you need may vary depending on your risk factors.

You'll see it on your sexual health STI tests, which are shown as “Accuracy from the period”. STD tests offer a high degree of accuracy if done correctly, but there are a number of situations that can result in an inaccurate result. These tests are the most reliable and preferred test methods (also called the “reference standard”) for screening for chlamydia and gonorrhea. A “false negative” is when the test result comes back negative when a person actually has an STD.
