A diagnostic test can tell you for definite that your baby has a problem. However, these tests do not detect every possible genetic or chromosome problem, only ones that are known.Before you make any decisions on which antenatal screening tests to accept or not, it is important that you and your partner think about the implications of the result.If the result is a ‘higher chance’ of a problem then you will be offered a diagnostic test.
