For health, you can eat fresh fruits and stay active, but for things like Down Syndrome, you must rely only on medical tests. Your doctor will suggest the right scans at 11-13 weeks, so please consult them.
Listen, there is no home test for this. You have to get the NT scan and double marker blood test done around the 3rd month. Just follow your gynecologist's prescription and get them done on time.
It's typically diagnosed through a screening process starting with the NT scan and double marker blood test in the first trimester. For definitive results, there are diagnostic tests like amniocentesis, but discussing with your doctor is always the best way forward.
My doctors explained the entire screening timeline to me very clearly. We did the NIPT test which is highly accurate, though a bit expensive. Just sit with your doctor and hospital coordinator to understand which test is right for you.
I remember being so nervous about these scans during my pregnancy before my C-section delivery. The doctor will guide you through the initial blood tests and scans, so please don't stress and focus on your healing and health.
They usually do a simple NT scan ultrasound between 11 to 13 weeks along with a double marker blood test. It's a standard screening that most labs do quite affordably, so just get it done when your doctor writes it.
