Antenatal Blood Tests (Bilan Prénatal)
The antenatal blood tests, often called the bilan prénatal, are a set of simple examinations offered to every pregnant woman, ideally at the first antenatal visit in the first trimester. They check the mother's health, detect infections that could be passed to the baby, and identify conditions that need special care during pregnancy and delivery.
At YGOPH, your midwife or doctor prescribes these tests at your first visit and completes them later in pregnancy as needed. Most can be done in our laboratory from one blood sample and one urine sample. For eligible women, the chèque santé and the universal health coverage (CSU) scheme may cover some antenatal tests; ask at the admissions office.
Which tests are included?
The core tests usually include your blood group and Rhesus factor, a full blood count to detect anaemia, HIV testing (free), syphilis serology (VDRL/TPHA), hepatitis B (HBsAg), a fasting blood glucose, and a urine test for protein, sugar and infection. Depending on your history and your doctor's advice, other tests may be added, such as haemoglobin electrophoresis if your sickle cell status is unknown, or toxoplasmosis and rubella serology.
- At the first antenatal visit, ideally before 12 weeks
- In the second and third trimesters, to repeat the blood count and screening tests as advised
- Between 24 and 28 weeks, a glucose tolerance test for women at risk of gestational diabetes
- For Rhesus-negative women, antibody screening during pregnancy
- At any time if you have symptoms such as fever, bleeding or swelling
Good to know
Why these tests matter
Each test has a purpose. Treating anaemia reduces the risks linked to bleeding at delivery. Treating syphilis prevents congenital infection. Knowing your HIV and hepatitis B status allows treatment that protects your baby. Knowing your blood group prepares the team for a transfusion if one is ever needed and allows prevention in Rhesus-negative mothers.
Later in pregnancy
Some tests are repeated. The blood count is usually checked again in the third trimester, HIV testing may be repeated, and women at risk of gestational diabetes are offered an OGTT at around 24 to 28 weeks. Your urine is checked for protein at your visits to detect pre-eclampsia early.
Costs and cover
The prices of the main individual tests are listed below, and HIV screening is free. For eligible women, the chèque santé, a single contribution of 6,000 FCFA per pregnancy, and the CSU scheme may cover antenatal visits and some tests. Ask the admissions office which tests are covered for you before paying.
