Can routine physical examination detect AIDS

In most cases, no, unless you actively request a special HIV test in addition to the regular package, or you have a special physical examination that includes HIV screening.

If you recall the annual physical examination organized by the company and the basic health examination package distributed free of charge in the community, it was nothing more than blood routine, liver and kidney function, blood lipids and blood sugar, chest X-ray, abdominal B-ultrasound, and at most a screening for common tumor markers. There would be no HIV-related test items from beginning to end. It’s not that physical examination institutions deliberately omit it. First of all, the price of routine physical examinations is generally not high, and HIV testing will increase the cost. More importantly, according to the requirements of the "Regulations on the Prevention and Treatment of AIDS", HIV testing is a special screening and must be carried out with the informed consent of the person. It is illegal for institutions to conduct testing without permission.

When I was helping in the municipal AIDS prevention and control volunteer team in the past two years, I would meet three or four people every week who came for consultation with physical examination reports from their workplaces. As soon as they walked in, they waved the "no abnormality" reports in their hands and asked: "My whole physical examination is fine, am I definitely not infected?" Every time I had to argue with them repeatedly: "health" in a routine physical examination has nothing to do with whether you are infected with HIV. Failure to do a special test means that you have not been tested. Let’s talk about an interesting episode. Previously, an aunt came for a free screening and said that her white blood cells were normal and she definitely couldn’t have AIDS. She really amused us. She repeatedly explained to her that the blood tests were for conventional blood indicators such as white blood cells and red blood cells, and could not identify HIV antigens or antibodies at all. They were completely different things.

Of course, there are exceptions. Many people say, "I was tested for HIV during my physical examination when I was taking the public examination/joining the army." This is actually a customized physical examination for special situations - civil servants, active military personnel, kindergarten teachers, blood bank staff and other special positions involving public services, as well as routine pre-operative examinations and pre-blood donation screenings. HIV is indeed included in the required examinations, but these do not fall into the category of "routine health examinations" we talk about every day and cannot be confused.

Even if you take the initiative to add an HIV test to your routine physical examination, it is not 100% possible to detect the results immediately. I met a young man before who went to the hospital for an additional test on the 10th day after committing high-risk behavior. When he got the negative result, he completely let himself go. As a result, he continued to have a fever the second month and went to the hospital for treatment. Instead, he was found to be positive. He happened to be stuck in the testing window. To put it bluntly, the virus has entered the body, but has not multiplied to a level that can be captured by the detection reagents. The commonly used fourth-generation detection reagents can detect both antigens and antibodies at the same time. The window period is about 2-4 weeks. The window period of the third-generation reagents that only detect antibodies is 3-4 weeks. To be safe, it is better to recheck high-risk behaviors after 3 months. If the result is negative, it can be completely ruled out.

The industry has also been discussing whether HIV testing should be directly included as an optional item in routine physical examinations, so that everyone can choose without asking. Those who support it believe that nearly 30% of HIV-infected people living in the country have not yet been discovered. Early screening and early treatment will not only make the life expectancy of infected people almost the same as that of ordinary people, but also significantly reduce the risk of transmission; those who oppose it are always worried about privacy leaks. After all, many people still have deep prejudices against AIDS. If the relevant results are accidentally leaked in the physical examination report, it is likely to bring unnecessary discrimination and trouble to the infected. There is no unified conclusion on this issue, and the practices of physical examination institutions in various places are also different.

If you have ever engaged in high-risk behavior and are feeling guilty, don’t wait for the annual routine physical examination. Either go directly to the local CDC. The test is completely free and anonymous. Your privacy is protected by law and will never be leaked. Or buy self-examination test strips from regular manufacturers and the results will be available in 15 minutes. Don’t panic even if the initial screening test is positive. Only the confirmed test results of the CDC will count. There is no need to scare yourself.

To put it bluntly, AIDS cannot be detected by routine physical examination. The core depends on whether you have done the corresponding special test. Don't be fooled by the statement that "the whole physical examination shows no abnormality."
