How many weeks of pregnancy can I do a DNA test

After a woman becomes pregnant, she needs to go to the hospital for various examinations to ensure that the fetus has no abnormal growth or development. If the fetus is found to have malformations, abortion may be required, which is painful for a family. Minimally invasive DNA and Down syndrome are both new programs for women to screen for fetal abnormalities after pregnancy. So, at how many weeks of pregnancy can a woman undergo a minimally invasive DNA test?

Women can go to the hospital for minimally invasive DNA testing between 12 and 23 weeks of pregnancy. Minimally invasive DNA testing is to analyze the fetal DNA in the mineral acid in the female's jugular vein blood, which can detect whether the fetus has Down syndrome and other sex chromosome problems. Therefore, it is necessary for women to carry out minimally invasive DNA testing after they become pregnant.

After five weeks of pregnancy, the fetus's DNA is stored in the blood of the female's jugular vein. The amount of this mineral DNA increases as the fetus's gestational age increases. It is not until 12 weeks into a woman's pregnancy that the fetal DNA can be tested and analyzed through a blood test to ensure that there are no abnormalities in the fetal chromosomes. If a problem is found after the minimally invasive DNA test, further amniocentesis will be needed to determine whether the fetus has abnormal development.

After it is confirmed that the fetus has abnormal growth and development, solutions should be adopted as soon as possible to reduce the harm to the woman's body. Sex chromosome disease is the most common type of birth defect in newborns, and it cannot be cured after the baby is born. Therefore, it is necessary to prevent this kind of situation from happening during pregnancy. Women are required to cooperate closely with doctors for examination to ensure that the baby has no sex chromosome problems.
