Identification methods

The procedures for fetal paternity testing are not complicated. The general procedure is to make an appointment - verify identity - take samples - identify - and provide report feedback. It should be noted that the chorionic villus biopsy operation needs to be performed through the lower vagina, and the leucorrhea must be clean, otherwise it is easy to cause uterine cavity infection; routine blood tests must also be performed, and it can be done if the white blood cell count is not high.

Pregnant women can choose to extract chorionic villus or amniotic fluid according to their pregnancy stage. For safety reasons, they must choose a Grade 3 obstetrics and gynecology hospital for the operation. Generally, doctors can collect fetal chorionic villus from pregnant women during the 10th to 13th week of pregnancy, and amniotic fluid from pregnant women during the 16th to 24th week of pregnancy. Obstetrics and gynecology hospitals with mature technology can collect amniotic fluid from 16th to 30th week of pregnancy.

Drawing venous blood is relatively simple. For pregnant women who are more than 7 weeks pregnant, about 10 ml of venous blood can be drawn from the pregnant woman's arm using an anticoagulant tube while ensuring hygiene.
