...when a baby can be diagnosed as down syndrome ?
Because I am pretty sure the huge amount of abortions happen before that.
Shit law regardless, even if I could see where they are coming from.
90% of abortions are performed before 12 weeks gestation (from the date of last menstrual cycle).
10% of abortions are performed in the second trimester or later.
1% of abortions happen after 20 weeks.
Early Prenatal Non Invasive Testing, such as Maternt21, Panorama, Verifi, and Harmony, can detect fetal blood in the mother's blood as early as ten week. The results on average take about 10 business days (or about two weeks) to get back. It is only considered a screening, it is NOT diagnostic. This is also done in conjunction with a 12 week NT scan. During this ultrasound, they look at the thickening in the neck area. Often times this can lead to heart defects if it is above 3mm thick and an increase is genetic abnormality. During this time, fetal hydrops can also be detected.
If a screening test comes back positive, a CVS test can be done between 11-13 weeks. This takes a small sample of tissue from the placenta for DNA testing. FISH results can usually take 48-72 hours, although full results generally take a week or longer to get back. A microarray can take up to two weeks to get back.
If the placenta is not in a position for testing, or the gestational period is above the 13 week limit, an Amniocentesis can be done 15 weeks and onward. This takes amniotic fluid from around the baby to test the DNA. Again 2 days for FISH results, a week for full, and two weeks for a microarray.
Most heart conditions can not be detected before the 18th week at the earliest, but on average between 20 and 22 weeks.
There are many genetic conditions that do not necessarily cause physical defects that can be detected by an ultrasound. The same goes for not all physical defects means there's an issue with the chromosomes.
Now there's also hundreds of genetic conditions passed down from parent to child. Some are recessive and require both parents to have an affected gene to have an affected child. Others are dominant (usually on the X chromosome) and only requires it to pass from one parent to have an affected child. Specific genetic testing can take on average 2 weeks if sent to a laboratory that does specific testing for specific conditions to 6 weeks or more if sent to just any lab that does DNA testing.
I am a genetic carrier of Fragile X. It's a dominant disorder, and my repeat count is a 150 (carrier status). Anything about 200 is considered full mutation (fully affected), and I have a 98% chance that the Fragile X gene will expand into a full mutation.
My first pregnancy took 4 weeks for results. My second pregnancy took 6 weeks for results. I terminated both pregnancies after 20 weeks.
