Is there a chance of contracting HIV?


Hello doctor, I recently went to the hospital for a check-up in the hepatobiliary and gastroenterology department due to weight loss and pain in the upper right abdomen.
After a blood test, my Neutrophil count was 75.4 and Lymphocyte count was 18.4.
I suddenly remembered that three years ago, I had unprotected sex with my ex-girlfriend, and I didn't get tested afterward.
I'm unsure if she had HIV at that time (she probably didn't).
Should I get tested for this now, or could my symptoms be simply due to stress? If testing is necessary, will it still be accurate after such a long time?

It's understandable to feel anxious about potential HIV exposure, especially after engaging in high-risk behaviors. Your concerns about your health and the implications of past actions are valid. Let's break down your situation and address your questions regarding HIV testing and the potential connection to your current health issues.

Firstly, regarding your past sexual encounter three years ago, if you engaged in unprotected sex with a partner whose HIV status was unknown, there is a theoretical risk of HIV transmission. However, the likelihood of transmission depends on several factors, including the HIV status of your partner at the time, the type of sexual activity, and whether any preventive measures were taken. If your partner was HIV-negative at that time, the risk would be significantly lower.

Now, concerning your current health issues, such as weight loss and abdominal pain, these symptoms can arise from various causes, including stress, anxiety, or other medical conditions unrelated to HIV. It's important to note that HIV infection can lead to symptoms, but these typically manifest much later in the infection process, often years after exposure. The acute phase of HIV infection usually presents with flu-like symptoms within 2-4 weeks after exposure, while chronic symptoms may not appear until the immune system is significantly compromised.

Regarding your blood test results showing elevated neutrophils and decreased lymphocytes, these findings can indicate an inflammatory response or infection, but they are not specific to HIV. Neutrophils are typically elevated in response to bacterial infections or inflammation, while lymphocyte levels can drop due to various reasons, including stress or viral infections.
Now, regarding your question about whether you should get tested for HIV: Yes, it is advisable to get tested, especially considering your past high-risk behavior. The good news is that modern HIV tests are highly accurate and can detect the virus even years after exposure. If you test negative now, it would be a strong indication that you are not infected, especially if you have not engaged in any further high-risk behaviors since that time.

Testing for HIV is straightforward and can be done through various methods, including rapid tests, which provide results in as little as 20 minutes, or standard blood tests, which may take a few days for results. The window period for most modern tests is about 2-4 weeks for initial detection, with conclusive results typically available at 3 months post-exposure. Given that three years have passed since your last potential exposure, you should be able to get a reliable result now.

In conclusion, while your current health concerns may be causing you stress, they are not necessarily indicative of HIV infection. However, testing is a proactive step you can take to alleviate your worries and ensure your health. If you are feeling overwhelmed, consider speaking with a healthcare professional who can provide support and guidance tailored to your situation. Remember, early detection and treatment of any health issue, including HIV, can lead to better outcomes and peace of mind.
