What are the tests that will be offered if my First Trimester Test result is screen positive?
If the test is screen positive, you will be offered a diagnostic test, usually chorionic villus sampling (CVS) or possibly an amniocentesis. The diagnostic test will determine whether or not the pregnancy is actually affected. CVS is offered early in pregnancy (usually between 10 and 13 weeks). It involves taking a sample of placental tissue (using local anaesthetic) either by inserting a needle through your abdominal wall or by passing a fine instrument through the cervix. CVS is performed under the guidance of an ultrasound scan and does not involve a stay in the hospital. The CVS sample contains cells which can be used to tell whether or not the baby has Down syndrome. A result is usually ready within 1 to 2 weeks. There is a small risk associated with the CVS procedure. About 1% of women who have CVS will have a miscarriage as a result of the procedure.
