Hearing is very important for a baby's future life, study, work, and interpersonal communication. If the baby's hearing loss is caused by congenital reasons, the impact on the baby is significant. Therefore, many doctors recommend doing a fetal hearing loss gene test. Due to a lack of understanding of the testing procedures for hearing loss genes, some parents have asked whether the screening for fetal hearing loss genes is accurate?
Screening for deafness genes is very necessary, and the accuracy of deafness gene screening results is still high, because if both or one of the spouses carries deafness genes, the probability of the fetus carrying deafness genes or suffering from deafness diseases will be greatly increased. Therefore, through screening for deafness genes, the goal of reducing disability rates and improving quality of life can be achieved.
When the fetus is not yet born, if genetic testing for deafness is needed, on the one hand, both parents can take blood samples for testing to see if both parents carry the deafness gene. If so, precautions should be taken to prevent the possibility of fetal deafness. Alternatively, amniocentesis can be performed by taking amniotic fluid samples for testing. As amniotic fluid contains fetal DNA, it is possible to detect whether the fetus carries the deafness gene, but it is important to note that amniocentesis carries certain risks for the fetus.
Therefore, if both husband and wife have pregnancy plans, they must undergo genetic testing for deafness before pregnancy. This can take effective measures to intervene or avoid the problems caused by deafness genes in advance, prevent the birth of deaf children. In addition, after the birth of the fetus, parents must also remember to do hearing and deafness gene testing for the baby. Only when both tests are passed can there be no problem.
