In the 36th week of pregnancy, the specialist may perform, in addition to the usual examinations of other visits, the third trimester check-up. This includes a blood and urine test and an ultrasound scan to assess various aspects of the baby, placenta and amniotic fluid.
The pregnant woman may also be screened for group B streptococcus. This test simply involves taking a vaginal-rectal swab sample from the woman and sending it to be tested for the presence of this bacterium. In case of a positive result, the woman will be given intravenous antibiotics at the time of delivery to reduce the risk of the baby getting an infection.
