What tests are included in early pregnancy screening?
Early pregnancy screening generally involves physical examination, laboratory tests, and ultrasound examination. The details are as follows:
1. Physical Examination
First, the pregnant woman's weight and abdominal circumference are measured. The physician will also inquire about the date of the last menstrual period and timing of intercourse to help estimate the expected delivery date.
2. Laboratory Tests
Blood tests, including complete blood count, blood glucose and comprehensive biochemical panel, as well as screening for infectious diseases, are performed to identify physiological changes during pregnancy and detect any infectious conditions. Additionally, the trend of rising HCG levels can be used to assess embryonic development.
3. Ultrasound Examination
Ultrasound is conducted to confirm the location of embryo implantation, evaluate the embryo's developmental status, and further determine the gestational age.
Early pregnancy screening is typically performed to determine the exact gestational age, estimated due date, potential risk factors during pregnancy, and the embryo's development. It is generally recommended to undergo these screenings under a doctor's guidance.
