Introduction
At 20 weeks of pregnancy, routine prenatal checkups include a urinalysis to detect the presence of protein in the urine. If elevated urinary protein is found, pregnancy-induced hypertension should be carefully monitored. A complete blood count can determine whether anemia is present, which might otherwise affect fetal growth and development. A four-dimensional color ultrasound can assess whether the fetus's bones, heart, skull, and limbs are developing normally and detect any malformations, as well as evaluate whether the amniotic fluid volume falls within the normal range.

Under normal circumstances, a 20-week pregnant woman should undergo routine prenatal examinations including urinalysis, complete blood count (CBC), and a 4D color ultrasound. The details are as follows:

1. Urinalysis

This test analyzes whether protein is present in the urine. If elevated urinary protein is detected, it may indicate a risk of pregnancy-induced hypertension, which requires prompt and early intervention.

2. Complete Blood Count (CBC)

This helps determine whether anemia is present. Anemia can negatively affect fetal growth and development and may cause symptoms such as dizziness or blurred vision in the pregnant woman.

3. 4D Color Ultrasound

This examination assesses whether the fetus's bones, heart, skull, and limbs are developing normally and checks for any malformations. It also evaluates whether the fetal size matches the gestational age, screens for conditions such as trisomy 21 (Down syndrome), and determines if the amniotic fluid volume is within the normal range.

Regular prenatal check-ups at the hospital are essential during pregnancy. Additionally, maintaining a balanced diet and avoiding late nights contribute to healthy fetal development and maternal well-being.
