If the fundal height is measured at 28 cm during a normal singleton pregnancy, what is the approximate gestational age?

In a normal singleton pregnancy, the fundal height, which is measured from the symphysis pubis to the top of the uterus (fundus), typically correlates closely with gestational age in weeks. Generally, the fundal height in centimeters tends to equal the number of weeks of gestation after about 20 weeks of pregnancy.

When the fundal height measures 28 cm, it most accurately corresponds with a gestational age of approximately 28 weeks. This correlation assumes that the pregnancy is progressing normally and that there are no significant deviations in fetal growth or amniotic fluid levels. Thus, when considering the changes in fundal height throughout pregnancy, a measurement of 28 cm is indicative of the fetus being around 28 weeks gestational age.

In summary, the measurement of the fundal height of 28 cm suggests the pregnancy is at the expected gestational age of 28 weeks.
