If you are in preterm labor or think you may be, your doctor may do some tests to monitor you and your baby. These tests include: Lab tests—These may involve testing blood, urine, and cells from the cervix or amniotic fluid to look for infection.Ultrasound—This test uses sound waves to create images of the inside of your body. In this case, the ultrasound is done to:
Examine the placentaCheck the baby’s ageLook for birth defects in the babySee the position of the babyMeasure the cervix and the amount of amniotic fluidAmniocentesis
—This test involves removing a small amount of amniotic fluid to look for infection or to see if the baby’s lungs are mature.
