mda aici verifica down syndrome, neural tube defects (spina bifida) si trisomy 18...toate sunt pe baza de teste de sange...acum am facut un research la chestia cu ultrasound si se poate depista pe baza de ultrasound dar trebuie facut cu un ecograf super performant...ii zice nuchal translucency screening
"Nuchal Translucency Screening (NT) — UCSF Medical Center is one of the few centers nationwide to offer nuchal translucency screening (NT) screening, a new, non-invasive test performed early in pregnancy to identify women at increased risk for Down syndrome and other birth defects. NT screening is performed between 11 and 14 weeks of pregnancy. It is offered to women of all ages. The screening is done via a high-resolution ultrasound exam of the nuchal area — a fold of skin at the back of the neck of the fetus. The results are combined with the mother's age to determine an adjusted risk for Down syndrome. The rate of detection for Down syndrome is about 80 percent. Based on the results, a woman has the option of undergoing CVS or amniocentesis for diagnosis.
NT is a screening test only and cannot determine with certainty if the fetus does or does not have Down syndrome, only if your risk seems to be high or low. While this test has been developed for Down syndrome screening, other chromosomal abnormalities can sometimes be detected. In addition, fetuses with an increased area of nuchal translucency are at risk for other birth defects. An additional ultrasound and fetal echocardiogram, an ultrasound of the fetal heart, can be performed at 18 to 20 weeks of gestation to look for these abnormalities, if indicated.
If the screening indicates that your fetus is at an increased risk of Down syndrome, a genetic counselor or physician will discuss the specific risk. The counselor also will discuss further diagnostic testing available, including chorionic villus sampling (CVS) or amniocentesis."
da, da si aici se cheama translucenta nucala sau ceva de genul asta. si se face cam la 12 saptamani de sarcina, si se interpreteaza ecografia impreuna cu rezultatul analizei de sange care se cheama dublu test. si apoi in functie de rez se merge la triplu test si asa mai departe.
