Questions about sexually transmitted infections (STIs)?


The test results I received a few days ago are: HSV 1 IgG 50.5 (+) and HSV 2 IgG 2.1 (+).
What do these results mean? Additionally, if I engage in unprotected sexual activity, can syphilis and HIV be detected six weeks later?

Gong, 50~59 year old female. Ask Date: 2012/11/15

Dr. Xu Weikai reply Urology


Hello, an HSV 1 IgG level of 50.5 (+) indicates a past infection with herpes simplex virus type 1, while an HSV 2 IgG level of 2.1 (+) indicates a past infection with herpes simplex virus type 2.
Most infections can be detected after 12 weeks, but at 6 weeks, it may not be detectable.
However, some infections may not be detectable until more than a year later, although such cases are rare.
Therefore, it is recommended to have blood tests after sexual activity: first test once, then again after 3 months, and a third test after 1 year.

When interpreting your HSV test results, it's important to understand what the numbers mean in the context of your sexual health. Your results indicate that you have tested positive for both HSV-1 and HSV-2, with HSV-1 IgG at 50.5 and HSV-2 IgG at 2.1.
Understanding HSV Test Results:
1. HSV-1 IgG Positive (50.5): This suggests that you have been exposed to HSV-1 at some point in your life. HSV-1 is commonly associated with oral herpes, but it can also cause genital herpes through oral-genital contact. A high IgG level indicates a past infection, which is typically not a cause for concern unless you are experiencing symptoms.

2. HSV-2 IgG Positive (2.1): This indicates that you have been exposed to HSV-2, which is primarily associated with genital herpes. The IgG test measures antibodies that your body has produced in response to the virus. A positive result means you have been infected with HSV-2 at some point, but it does not necessarily mean you are currently experiencing an outbreak.
What to Do Next:
- Consult a Healthcare Provider: It's essential to discuss these results with a healthcare provider who can help interpret them in the context of your symptoms and sexual history. They can also provide guidance on managing the infection and reducing the risk of transmission to partners.

- Consider Additional Testing: If you are experiencing symptoms or have concerns about your sexual health, further testing may be warranted. This could include swabs of any active lesions or additional blood tests to confirm the type of HSV and assess your immune response.

Regarding STI Testing After Unsafe Sex:
- Timing for Testing: After engaging in unprotected sex, it is generally recommended to wait at least 2-3 weeks before testing for STIs like HIV and syphilis. This is because it can take time for the body to produce detectable antibodies. For HIV, the window period can vary depending on the type of test used (antibody tests, antigen/antibody tests, etc.).
- HIV Testing: If you had unprotected sex, it is advisable to get tested for HIV. Depending on the test used, you may be able to get accurate results as early as 2-4 weeks after exposure, but for the most reliable results, testing at 3 months is often recommended.

- Syphilis Testing: Similar to HIV, syphilis can be tested for after a few weeks post-exposure, but again, testing at 3 months is often recommended for definitive results.

Psychological Impact: It's understandable to feel anxious or overwhelmed after receiving positive results for HSV or after potential exposure to STIs. It's important to remember that many people live with HSV and manage it effectively. Seeking support from healthcare professionals, counselors, or support groups can help alleviate some of the emotional burden.

In summary, your positive HSV-1 and HSV-2 IgG results indicate past infections, and while they may raise concerns, they are manageable with the right information and support. Testing for other STIs after unprotected sex is crucial, and timing is key for accurate results. Always consult with a healthcare provider for personalized advice and treatment options.
