Can a routine blood test detect AIDS?

In general, a routine blood test cannot detect HIV/AIDS. If needed, it is recommended to consult a doctor. The detailed explanation is as follows:

The main purpose of a routine blood test is to assess the basic components and condition of the blood, including red blood cell count, hemoglobin levels, white blood cell count, etc. These indicators are primarily used to determine the presence of blood-related conditions such as anemia, infection, or inflammation. However, AIDS is caused by infection with the human immunodeficiency virus (HIV), and this viral infection does not directly cause specific changes in routine blood test indicators. Even if a person is infected with HIV, a routine blood test typically will not show specific abnormal results.

Diagnosis of AIDS requires specific HIV testing, including HIV antibody testing, HIV antigen testing, and HIV nucleic acid testing. These tests can directly detect HIV antibodies, antigens, or viral nucleic acids in the blood, thereby accurately determining whether an HIV infection exists. However, routine blood tests cannot provide this critical information and therefore cannot be used for diagnosing AIDS.

In daily life, it is important to enhance self-protection awareness, avoid unprotected sexual contact with individuals infected with HIV, and avoid sharing needles or syringes.
