OSCAR or NIPT

I would recommend NIPT. For my 1st pregnancy at 29, I went with OSCARS and had a false positive which was worrying! Knowing that it has a lower chance of accuracy we ended up doing NIPT too for a peace of mind and all was good thankfully. To save money and if you can afford, should just go ahead with NIPT since it has a higher accuracy despite it being more expensive.
