Pre-pregnancy genetic testing

We all know that in order to ensure eugenics, women need to have both male and female bodies checked before becoming pregnant. This is because some genetic factors are recessive and some diseases are inherited from generation to generation, so some examinations are necessary to prevent these genetic diseases. So what do women check for in prenatal genetic examinations? The editor will give you a detailed introduction below.

Pre-pregnancy check-up refers to a physical examination at the hospital before a couple prepares to become pregnant, in order to ensure the birth of a healthy baby and achieve eugenics. Pre-pregnancy check-ups are different from routine physical examinations and are mainly examinations of the reproductive system and genetic factors. A pre-pregnancy checkup of relevant items by both husband and wife is the basic guarantee for the lifelong health of the child. A healthy baby must first be the result of the combination of healthy sperm and egg, so men also need to be examined. The best time for prenatal check-up is 3 to 6 months before pregnancy.

1. Prevent birth defects

The annual birth defect rate of newborns in my country plus the congenital disability rate between the ages of 0 and 14 years old is 4% to 6%. This means that there are 800,000 to 1.2 million new children with congenital disabilities in my country every year.

Among the Chinese population, the number of people with congenital intellectual disabilities has reached 30 million, and the number is increasing at a rate of 2% each year. In my country, on average, one baby with congenital idiocy is born every 20 minutes, and one baby with neural tube defects is born every 6 minutes. The direct economic losses caused by neural tube defects alone exceed 200 million yuan each year.

2. Prevent the transmission of genetic diseases

If there are obvious genetic disease patients in the family, people will pay attention to related examinations when giving birth and consciously consult a doctor. However, some parents, like normal people, are carriers of certain genetic disease genes. Although they themselves do not suffer from the disease, they are very likely to pass this genetic disease on to the next generation. For example, a child with albinism may have normal parents, but the child has fair skin and yellowish hair.

Currently, there are thousands of genetic diseases, and most of them have no cure. Once a child with a genetic disease is born, it will bring troubles and heavy burdens to the child, the family and society because there is no cure. Therefore, the key to genetic diseases is prevention, and various screening methods should be adopted to prevent the birth of children with genetic diseases.
