Non-invasive testing using blood samples can only be done at 6 weeks from conception (this means you will be in your 8th week of pregnancy, starting from the first day of your last menstrual period).

The time lapse required for invasive testing is longer than with our risk-free test. In fact, amniocentesis is between 14 and 20 weeks while CVS testing can be performed earlier in 10 to 13 weeks.
