Quad 4 test results

Miriah
I got my quad test results & it said I was high risk for my baby to have Down syndrome... It gave me a 1/231 chance which I guess is high for a 30 year old. 
I'm of course, freaking out.... Even though they say these tests have false positives all of the time. 
Anyone else experience this? It recommended me get an amnio and/or genetic counseling.
