67.1Practice summary — testing for chromosomal anomalies


When — At the first antenatal visit

Who — Midwife; GP; obstetrician; Aboriginal and Torres Strait Islander health worker; multicultural health worker; genetic counsellor

  • Discuss the process of testing for chromosomal anomalies — Explain the purpose, the process involved and that it is the woman’s choice whether any tests are carried out.

  • Consider timing — For women who choose to have combined first trimester testing, make arrangements for the tests to be carried out before 13 weeks and 6 days pregnancy. If a woman elects to have cfDNA testing, this may be conducted from 10 weeks.

  • Offer women with a high-probability result referral to an appropriately trained health professional — This may assist women in considering options and making decisions about diagnostic testing. If a diagnostic test is carried out and chromosomal anomaly diagnosed, referral for counselling should occur at the earliest opportunity.

  • Learn about locally available resources — Available testing services and support organisations will vary by location.
