First trimester blood results

Catherine

I just got mine back at it said I screened negative which is great but it also said my age risk for downs was 1:570. I’m 29 years old and based on what I’ve seen online I thought I was closer to 1:1000 for my age? Any ideas? Does that seem normal? My mss (maternal serum) risk is 1:455 and again seems like people get results in the thousands like 1:7000 and higher!! I know I shouldn’t worry but it’s hard not to. Any body else feel like their numbers were lower than expected?
