00:09Hello health friends and strong parents.
00:13Every expecting parent naturally hopes for their baby to be born safe, sound, and in perfect health.
00:21However, genetic factors can sometimes cause abnormalities in the fetus's chromosome count or structure,
00:27leading to conditions like Down syndrome, spina bifida, and thalassemia.
00:34The good news is that advancements in medical technology now allow us to detect chromosomal abnormalities while the baby is
00:41still in the womb.
00:43Let's discuss safe non-invasive screening methods, along with the three main diagnostic procedures and their risk levels.
00:53Non-invasive early screening, ultrasound, NT, NIPT.
01:02Before moving on to advanced diagnostic testing, doctors usually recommend non-invasive screening,
01:08which is 100% safe for the baby, between 11 and 20 weeks of pregnancy.
01:14These methods include, routine ultrasound, nuchal translucency, NT, scans to measure the fluid at the back of the baby's neck,
01:22and advanced NIPT, non-invasive prenatal testing, blood tests.
01:30This initial screening helps determine whether the fetus has a high or low risk for chromosomal abnormalities,
01:36without any risk of miscarriage.
01:39Three invasive diagnostic tests, amniocentesis, CVS, FBS.
01:50If screening shows a high risk, only then will your doctor consider invasive diagnostic testing.
01:58First, CVS, chorionic villus sampling takes a placental tissue sample between weeks 10 and 13 of pregnancy,
02:06with a miscarriage risk of around 1%.
02:11Second, amniocentesis, takes a sample of amniotic fluid between weeks 15 and 20 of pregnancy,
02:17with a very low miscarriage risk of under 1%.
02:22And third, FBS, fetal blood sampling takes blood directly from the umbilical cord.
02:28FBS carries the highest risk of miscarriage,
02:31so it is only performed if CVS or amniocentesis is not possible.
02:37Understanding chromosomal abnormalities and prevention.
02:45Some of the detectable conditions include Down syndrome, a trisomy on chromosome 21,
02:51spina bifida, a neural tube defect in the spine,
02:55and thalassemia, an inherited red blood cell disorder.
03:00Although genetic conditions cannot be fully cured,
03:03early detection gives medical teams valuable time to prepare appropriate obstetric interventions
03:08and postnatal care.
03:11For expecting mothers, make sure to always take adequate folic acid starting from preconception
03:16to help prevent neural tube defects such as spina bifida.
03:22Conclusion and final educational note.
03:29Regular prenatal checkups or antenatal care are the wisest step to monitor your baby's growth
03:35and development.
03:38Don't hesitate to consult your OBGYN about whether chromosomal screening is right for you,
03:43especially if you have a family history of genetic conditions
03:46or are pregnant over the age of 35.
04:00Wishing good health to both mom and baby.
