Can HIV be detected when donating blood?

If the blood donor is in the window period of HIV infection, there is no way to detect it.

This is called the window period of HIV. If a blood donor donates blood during this period, there is no way to detect it with current testing technology. HIV is present in the patient's body at this time. Therefore, the blood of an infected person in the window period is also contagious. At present, the window period of HIV is 14 to 21 days, and it can be detected during a blood test outside the window period.
