Questions about this page

Questions about chorionic villus sampling (cvs)

These answers are general. Individual advice depends on the clinical history and assessment.

Reception can help with appointment details

No. It is a diagnostic procedure used to analyse placental genetic material for selected conditions.

Timing, the clinical question, placental position and patient preference may influence the choice after counselling.

No. The result is limited to the laboratory tests requested and the biological limitations of placental sampling.

Counselling should cover procedure-related pregnancy loss, bleeding, infection, insufficient sample and the possibility of uncertain or placental-confined results.

Contact the clinical team urgently for heavy bleeding, fluid leakage, fever, severe pain or feeling acutely unwell.
