Is genetic testing necessary for pregnant women?

Genetic testing for pregnant women is also a common part of prenatal examinations and has relatively important significance. It mainly checks whether the chromosomes are normal. If there is a gene mutation, the child born may also carry this gene. In addition to genetic testing, there are many other things that need to be checked in the early stages of pregnancy. Good examinations help the fetus develop well. Let's take a look at this aspect.

Is genetic testing necessary for pregnant women?

It is absolutely necessary. The chromosomes of one party are normal, but the genes of the two may have other mutations when they combine. Some genes of ancestors have appeared in previous generations and may exist in the next generation, but they are recessive gene mutations.

Early pregnancy check

1. Gynecological speculum examination

Understand the condition of the vagina and cervix, rule out abnormal development of the pregnant woman's reproductive organs, and provide a channel for the baby to be born smoothly; observe whether the vaginal mucosa is congested, whether the color and amount of vaginal secretions are normal, and whether there is any odor; see whether the cervix is ​​eroded and whether there are cervical polyps; especially when bleeding occurs in early pregnancy, observe whether the cause of bleeding is related to the vagina and cervix to provide a basis for treatment.

2. Leucorrhea examination

Find out whether there are Trichomonas or fungi in the vagina, and if necessary, conduct chlamydia, mycoplasma, and gonococcal tests. If the above microorganisms are present, it is easy to cause ascending infection, affect embryonic development and induce miscarriage.

3. Cervical smear test

Because blood volume increases and blood supply is abundant during pregnancy, if a tumor occurs in the cervix, timely treatment can improve the survival rate. Therefore, this examination is mainly to understand the morphology of cervical epithelial cells and rule out the occurrence of cervical tumors. Of course, cervical smear examination is a relatively basic examination method. When doubts arise, further colposcopy or cervical biopsy pathological section can be performed to confirm the diagnosis.

After reading the above introduction, I believe everyone knows whether genetic testing during pregnancy is necessary. It is quite necessary because it can detect some recessive genetic diseases. In addition, various examinations done during pregnancy cannot be missed and have relative significance. Therefore, pregnant women should actively cooperate with prenatal examinations, for themselves and for their children.
