They should get adequate rest and avoid strenuous exercise. The evening meal the day before the blood test can be eaten as usual, but no food or drink (except water if necessary) should be consumed after dinner. It's important to remain fasting before the blood draw. If any discomfort occurs, it is recommended to seek medical attention promptly and receive standardized treatment under a doctor's guidance.

Can blood tests detect AIDS?

Whether blood tests can detect HIV depends mainly on the stage of infection. After the window period, when the viral load is high and sufficient antibodies are present, blood tests can usually determine whether a person has HIV.
