The RCOG has published an updated version of Green-top Guideline 8 - Amniocentesis and Chorionic Villus Sampling
It is estimated that around 5% of the pregnant population (approximately 30 000 women per annum in the UK) are offered a choice of invasive prenatal diagnostic tests (most commonly amniocentesis or chorionic villus sampling). The type of diagnostic test available and offered is likely to vary depending upon the timing of any initial screening test that is performed. The aim of this guideline is to set a series of evidence-based standards to ensure a high level and consistency of practice in the provision and performance of amniocentesis and chorionic villus sampling.
