Trisomy 21 and trisomy 13/18 results advice

[Kimdsmiff]

Hi there
Is it better to have lower figures or higher?
I’ve tried googling for answers and I’m getting nowhere
My son was :
Trisomy 21 = background 1.156 adjusted 1.3121
Tri 13/18 = background 1:1293 adjusted 1:20000

My baby I’m carrying is:
Trisomy 21 = background 1:101 adjusted 1:2019
Tri 13/18 = background 1:837 adjusted 1:16727

Is it better to have lower number results or higher?

The higher the better,you are high risk if your number is under 1:120 and low risk above this, so 1:2000 and 1:16000 is great! Mine was 1:6000 and 1:15000 so very low risk

It is all based on age and blood work etc, my numbers were better last time as i had my son 3 years ago age 22
