The HIV virus that causes AIDS usually appears in blood analyzes during what is known as the window period, which is the period between the beginning of a person’s exposure to the virus and between the time the virus appears in the analyzes, and this period usually lasts between 10 to 90 days, and varies According to the reactions of the patient’s immune system, and the type of analyzes that are performed.

It should be noted that sometimes the result of the analysis can be negative during the window period, despite the presence of the virus in the body. The virus can be transmitted from one person to another during this period, and its transmission rate is higher due to the high levels of the virus in the body during that period.

Sometimes an antigen test (antibody test) can be done on a blood sample from a vein, and this test can usually detect the presence of HIV (the virus that causes AIDS) within 18 to 45 days after infection. Blood test results usually appear within the same day or within several days of the analysis.

And after knowing when AIDS appears in a blood test? It should be noted that there is no HIV test that can detect the virus immediately after infection, and in the event of suspicion of infection within the last 72 hours, you should speak with a doctor immediately.
