Can Routine Blood Tests Detect STDs Like HIV?

Blood test?

Hello, Doctor: I had a boyfriend three years ago (we broke up three years ago), and he was my first boyfriend.
After we broke up, I found out that he had a rather promiscuous sex life, having been with several partners.
I'm very worried that he might have some infectious diseases.
Q_Q We did not have sexual intercourse, only kissed and had oral sex...
(but it wasn't for long, and he did not ejaculate).
Over six months ago, I had a full body check-up, including blood tests, and all the results were normal.
So I would like to ask the doctor: Can a general health check-up blood test detect any sexually transmitted infections? For example, HIV? (I am particularly concerned about this issue.)

If the health check report contains the terms HIV/AIDS or the Chinese description of AIDS or Human Immunodeficiency Virus (HIV) syndrome, it indicates that an HIV test has been conducted.
If it is unclear whether the above tests were performed, it is recommended to have another blood test for confirmation.

Routine blood tests, such as those conducted during general health check-ups, typically do not include specific screenings for sexually transmitted diseases (STDs) like HIV unless specifically requested. Standard blood tests usually focus on assessing overall health markers, such as cholesterol levels, blood sugar, liver function, and complete blood counts. Therefore, if you are concerned about potential exposure to HIV or other STDs, it is essential to request specific tests for these infections.

HIV testing can be performed using various methods, including antibody tests, antigen tests, and nucleic acid tests (NAT). The most common initial screening test is the HIV antibody test, which detects antibodies produced by the immune system in response to HIV infection. However, it is important to note that there is a "window period" after infection during which these antibodies may not be detectable. For most antibody tests, this window period is typically around 3 to 12 weeks, depending on the specific test used.

In your case, since you mentioned that you had no sexual intercourse with your ex-boyfriend and only engaged in kissing and oral sex without ejaculation, the risk of HIV transmission is significantly lower. However, it is still advisable to be cautious, as oral sex can carry some risk of transmission, especially if there are cuts or sores in the mouth.

If you had a comprehensive health check-up six months ago and the results were normal, it is possible that HIV was not included in the tests unless specifically requested. If you are feeling anxious about your sexual health, it would be prudent to consult with a healthcare provider and discuss your concerns. They can recommend appropriate testing based on your history and risk factors.

For individuals who are at higher risk or have had potential exposure to HIV, healthcare providers often recommend routine testing. The Centers for Disease Control and Prevention (CDC) advises that everyone between the ages of 13 and 64 should be tested for HIV at least once as part of routine healthcare. Those with higher risk factors, such as multiple sexual partners or a history of unprotected sex, should consider more frequent testing.

In summary, while routine blood tests may not automatically screen for STDs like HIV, you can take proactive steps to ensure your sexual health by requesting specific tests. If you have any concerns about potential exposure or symptoms, do not hesitate to reach out to a healthcare professional for guidance and testing. It is always better to be informed and take the necessary precautions to protect your health.
