In some cases, hepatitis B and C may not cause any obvious symptoms for years. If they do appear, hepatitis B usually produces signs within 6 weeks to 6 months. Hepatitis C symptoms may appear as early as 2—6 weeks, but can sometimes take as long as 6 months. A blood test can look for both types of hepatitis. The hepatitis B testing window is 3—6 weeks, while the hepatitis C testing window is 2—6 months.
Early testing at 2 months may miss some cases, so a doctor may recommend retesting at 6 months. A doctor can test for trichomoniasis with a swab of the rectum, penis, or vagina. Many people do not have symptoms, but some may notice a discharge or burning sensation within 5—28 days of exposure. It is possible to get a positive test within a week of exposure, though some people need to wait up to a month. Syphilis usually begins with a sore on the genitals called a chancre.
Blood tests can detect the bacteria within 1—2 weeks after the chancre appears. Chancres are typically painless and usually develop within 3 weeks of exposure, so the total testing window is about 4 weeks. Because the development of syphilis varies from person to person, doctors often recommend retesting about 3 months after exposure. Some STIs live in the body for many years without triggering any symptoms. Doctors may refer to them as dormant, meaning a person can never diagnose themselves based on symptoms alone.
This also means if a person is untested, they can unknowingly pass a dormant STI on to a sexual partner. The CDC recommend that all sexually-active adults with new or multiple partners seek testing for most STIs at least once per year. STI testing, even for incurable infections, can save lives. It also slows the spread of STIs. Some benefits of testing are below:. It is important for people to regularly test for STIs, particularly if they have sex with multiple partners.
Early detection can make treatment easier and possibly prevent serious health issues. To reduce the risk of STIs, people should also practice safer sex techniques, such as using a condom. In addition, even after the incubation period has passed, there are some STDs that can take months or years to produce symptoms. Since most STD tests use antibodies not symptoms as a marker of disease status, having symptoms is not necessarily a reliable marker of infection.
Every STD has its own incubation period. For some STDs, the body begins to produce antibodies and symptoms in as little as a few days. For others, it can take weeks or months for symptoms to appear.
Here are the ranges of incubation periods for some of the most common STDs. The expanded STD incubation and testing chart below includes test type and retesting recommendations. After the incubation period has passed, most STDs can be diagnosed via antibody-specific blood tests. Some STDs are also accompanied by lesions and can be diagnosed via swab, culture, or urine tests as well.
In the case of a lifelong viral infection, a blood test will always detect the STD, even after treatment has been successful. Therefore, retesting would only be necessary if you wanted to reconfirm an original diagnosis.
