[00:00:00]Now, if you don't want to do amniocentesis, which I don't blame you, most people don't, [music] but you still want testing, there are several blood tests that you can do, like the quad screening, which is just a blood test that can check for Down syndrome, spina [music] bifida, trisomy 18. This test is usually done somewhere between 15 and 18 weeks, but it can be done up to 22 weeks. So, just remember, this [music] is just a screening test, and even if you get a negative result, it doesn't absolutely guarantee that your baby doesn't have a genetic disorder. And if it's positive, it doesn't mean that there is a 100% chance that your baby does. If your quad screen does come back positive, your OB might want to discuss further testing if you want to do it.
