Screening tests during pregnancy: Antenatal Screening blood test

Blood tests are a routine part of your antenatal care. The antenatal screening blood test is necessary as it provides both you and your doctor essential information about your health, in addition to scanning for any abnormalities in your blood.

Your first blood test (at your first antenatal visit during the first or second month of pregnancy) will include the ABO group blood test. This test checks for your group type and the presence of antibodies that are part of your immune system. Certain antibodies could harm your baby during pregnancy. If antibodies are found to be harming the baby, appropriate management and treatment will be recommended by your doctor.

Haematology is conducted to examine three main types of cells in the blood: red blood cells, white blood cells and platelets. This will determine if there is any blood disorder in the mother, which could potentially affect the baby.

The blood test also screens for Hepatitis B, Rubella (German measles) and sexually transmitted diseases such as STD, HIV and Syphilis.
