Introduction
Prenatal blood tests include screening for several infectious diseases, one of which is HIV testing. By detecting HIV antibodies or viral nucleic acids in the blood, it can be determined whether a pregnant woman is infected. Since the HIV virus may be transmitted from mother to child through vertical transmission, early detection allows timely interventions such as antiviral treatment to reduce the risk of fetal infection and ensure the safety of both mother and child.
Generally, prenatal blood tests include screening for HIV, which is a standard procedure to ensure maternal and infant health. If you have concerns, it is advisable to consult your doctor in advance to confirm the specific tests involved. The detailed explanation is as follows:

If a pregnant woman has engaged in high-risk behaviors, such as unprotected sex or sharing needles, the doctor may recommend increased testing frequency or more detailed viral load testing. If a woman is already diagnosed with HIV, she should follow standardized treatment under medical supervision and undergo regular monitoring of her condition.
Before prenatal testing, it is recommended to remain fasting and avoid strenuous exercise to ensure accurate test results. If there are special requirements or questions regarding the tests, it's best to discuss them with the doctor beforehand to develop a personalized testing plan.
