Nervous and scared?
Hello, doctor.
I have a few questions to ask.
I visited a special venue at the beginning of February and had oral sex with a sex worker.
Since then, I have developed some symptoms and I'm very worried about possibly contracting a disease.
I plan to get tested for HIV and syphilis through a blood test at the tenth week.
Will the accuracy of the results be an issue? Additionally, two weeks ago, I started to notice small red spots on my skin (which appeared before the blood test) that look like flat moles.
They are not raised.
After that, I began to develop pimples.
I'm very concerned that these might be symptoms of HIV.
Since I had a blood test at the tenth week, is it necessary for me to wait until the twelfth week to get tested again? I would greatly appreciate your guidance.
Thank you.

Hello, I would like to mention that a standard HIV serum test typically shows a positive reaction around 6 to 8 weeks after exposure, meaning that is when it can be detected.
By the tenth week, it should theoretically be conclusive; however, some testing facilities may have issues with their testing reagents due to factors such as storage conditions or expiration, which can lead to inaccurate results.
My recommendation is to seek out accredited laboratories (such as those with ISO-17025 certification) or larger hospitals, as they tend to have higher reliability.
Note: Testing data from internationally accredited laboratories, backed by ISO certification, is generally more trustworthy.
Sincerely, Dr.
Hsu Wei-Kai, Director of Urology, Taitung Hospital, Department of Health, Executive Yuan.

More Info
It's understandable to feel anxious after engaging in unprotected sexual activities, especially in a situation that raises concerns about sexually transmitted infections (STIs) like HIV. Your experience is not uncommon, and many individuals face similar worries after potential exposure.
To address your concerns, let's first discuss the timing and accuracy of HIV testing. The window period for HIV testing refers to the time after potential exposure during which the virus may not be detectable in the blood. For most standard HIV tests, including the antibody tests, the window period is typically around 3 to 12 weeks. However, many modern tests, such as the fourth-generation tests, can detect HIV earlier, often within 2 to 4 weeks after exposure.
Since you mentioned that you had an HIV test at the 10-week mark, this is generally considered a reliable time frame for testing. The accuracy of the test you underwent is likely high, especially if it was a fourth-generation test that checks for both antibodies and the p24 antigen. However, it is important to note that while a negative result at 10 weeks is reassuring, it does not completely rule out the possibility of infection. The CDC recommends retesting at 3 months (12 weeks) post-exposure for conclusive results. Therefore, it would be prudent to get tested again at the 12-week mark to ensure you have the most accurate information regarding your HIV status.
Regarding the symptoms you are experiencing, such as the skin rash and the appearance of spots, it's important to remember that many STIs, including HIV, do not present with specific symptoms that can be easily identified without testing. The symptoms you describe could be related to various conditions, including allergic reactions, other infections, or even anxiety-related skin issues. While some individuals may experience a rash during the acute phase of HIV infection, it is not a definitive symptom, and many other conditions can cause similar skin changes.
If you are experiencing persistent or concerning symptoms, it is advisable to consult a healthcare professional for a thorough evaluation. They can assess your symptoms in the context of your sexual history and provide appropriate testing and treatment if necessary. Additionally, if you have engaged in sexual activities with other partners since your initial exposure, it is essential to communicate with them about your situation and encourage them to get tested as well.
In summary, while your 10-week HIV test is a good indicator of your status, it is recommended to follow up with another test at the 12-week mark for conclusive results. Pay attention to your symptoms, and do not hesitate to seek medical advice if you have concerns. Remember, early detection and treatment of STIs are crucial for your health and the health of your partners.
