I have been worried about the downs and Edward's test results I received. For my first baby (pregnant in 2021 I received a letter saying I tested negative and also it was 1 in 50,000 chance) for this baby it did not say anything about being negative and instead said I was 1 in 5,000 chance for both and 1 in 1,000 chance for my age. I've read online that the benchmarking for results has changed and wanted to check that this was the case as 1 in 50,000 to now 1 in 5,000 is very different - should I be concerned about this?! Thanks
