[A comparison of skilled methods to determine gestational age in pregnancy]

A group of 208 antenatal women at a primary health care clinic in Bloemfontein was selected for the study. Fundal height was determined by measuring the height of the fundus as well as using the uterine fundus height in relation to weeks method. The above-mentioned methods were compared with a sonar date to determine whether a specific method is more accurate in a specific stage of pregnancy. It seems as if measuring of the height of the fundus is more accurate in the second trimester. In the third trimester of pregnancy a tendency exists for both the uterine fundus height in relation to weeks method and measuring of the height of the fundus to be accurate until the 36th week of pregnancy. After the 36th week of pregnancy the uterine fundus height in relation to weeks method seems to be more accurate.
