Hello doctor! I am 38 years old and pregnant for the third time. I tested for Trisomy 21 and the ratio is 1/159. So doctor, can you tell me if the Trisomy 21 test ratio is 1/159, is it dangerous and what should I do next?

am 32 years old this year. I am 23 weeks pregnant with my second child. I went for a check-up and all the indicators are normal except for the baby's nasal bone measuring 5.5mm. The doctor said that the baby's nose is a bit shorter than the standard, because at week 20, the baby's nasal bone measured 5.2mm. I did the Double test at week 12 and the risk was low at 1:547. So doctor, can you tell me if a 23-week-old fetus has a short nasal bone? Is my baby likely to have Down syndrome? Is the NIPT test accurate now?

am 16 weeks pregnant with my first child (history of 2 stillbirths at 6 weeks and 8 weeks). Last month, I did a Double test, the results for Down syndrome are as follows: Nuchal translucency 1.3mm, cut off 1:250, risk based on mother's age 1:1272, total risk 1:712. So doctor, can you tell me if a fetus has a nuchal translucency of 1.3mm, what are the effects?

Hello doctor! Currently, I am 17 weeks pregnant and did the 1st test, the Double test 21 was 1:4967, the second time I did the Triple test 21 risk 1:4506. After the second examination, a 2.8mm left ventricular hyperechoic nodule was found.

I have a congenital heart defect. So, doctor, let me ask if women with congenital heart disease can pass it on to their children? Thank you doctor.

Double test is a genetic screening test for the fetus based on the mother's blood sample in early pregnancy. Whether or not to perform the Double test requires fasting is currently a concern of many pregnant women.

Double test is one of the routine screening tests, recommended for all pregnant women to screen for common chromosomal disorders in the fetus such as Down, Edwards and Patau syndromes.

DNA-free prenatal screening is a non-invasive prenatal screening method with no risk of miscarriage, with a high disease detection rate and low false positive and false negative rates compared to traditional serum screening methods.

Double test prenatal screening test is used to screen for some genetic syndromes in the fetus. Knowing how to read the Double test results correctly will help parents better understand the health status of the fetus.

Edward syndrome is a rare genetic disorder that affects babies. Children with Edward syndrome are unlikely to survive after birth and, if they are lucky enough to be born, will develop abnormally. It is the second most common syndrome, after Down syndrome, with a rate of 1/3,000 to 1/8,000 newborns affected.

Edwards syndrome is a rare genetic disorder in fetuses, caused by an extra copy of chromosome 18 in the genome. When children have this syndrome, they often have developmental delays and may have other serious birth defects.
