Is the test accurate after 3 months of suspected HIV infection?

Question

Doctor, I would like to ask about my health. More than four months ago, I noticed some symptoms similar to those of HIV. After two weeks, I went for testing, and the result was negative. Three months later, I tested again, and that result was also negative. However, I still feel worried because now, four months later, I am experiencing some symptoms such as: body aches, occasional sharp pains, a white tongue, and weight loss. I am very concerned and hope you can explain whether I might have HIV or if I could be suffering from something else.

Hello. When you receive a negative test result, it means that there are no antibodies against the HIV virus in your blood. This also indicates that you are not infected with HIV. However, there are some cases where exposure is still in progress. Therefore, you need to fully adhere to the retesting timelines set by your doctor.
After 3 to 6 weeks, the symptoms of infection begin to decrease, and 95% of those infected remain healthy and do not suspect they are infected. Testing for HIV during this time may not ensure high accuracy. Some people may present early symptoms of HIV infection that resemble common flu symptoms.
The infection progresses silently. The most accurate HIV testing is typically done after about 2-3 months.
A negative result after 4 months of testing is a safe conclusion. If the result is negative, you can be completely assured that you are not infected. Conversely, if the result is positive, it means you have contracted HIV.
Before the test, you should not take any medication (as some medications can affect the accuracy of the test results). Avoid alcohol or any stimulants (which can also impact accuracy).
Thank you for your question to the Vinmec Healthcare System.
