I turned 30 in December last year and the only test I took besides the normal blood test in the first trimester was the blood test for chromosome deformities and gender in the second trimester.
I was 35 when I had my first and I am pregnant now at 37. I haven't had any special testing done at all. I bypassed the genetic testing and my doctors didn't seem concerned with that at all. As long as you are healthy you should be treated just as a patient that is younger.
