When I got my test results, they were clear that the odds of having a disorder were (for example) 1/144, even with a ‘positive’ result. This was through Natera. The problem is that this information is sent directly to the provider in most cases, so parents are left interpreting someone else’s interpretation of statistics. My midwife specifically told me that the test isn’t often wrong, even though the actual odds were there in the fine print.
