WHO Recommendations on Antenatal Care for a Positive Pregnancy Experience. The synthesis of an evidence-based algorithm for IPDT is of crucial importance to healthcare professionals implicated in prenatal care to avoid unnecessary interventions without compromising optimal prenatal care.Īmniocentesis chorionic villous sampling (CVS) complications indications invasive prenatal diagnostic testing technique. Periprocedural management regarding Rhesus alloimmunization, virologic status and use of anesthesia or antibiotics are either inconsistent or insufficiently addressed. Certain technical aspects and the overall approach demonstrate significant differences. The earlier time for amniocentesis is unequivocally set at ≥15 gestational weeks, whereas for CVS, the earlier limit varies from ≥10 to ≥11 weeks. Other indications arise from medical history and sonography, with significant variations identified between the guidelines. All the reviewed guidelines highlight that IPDT is indicated based on a positive screening test rather than maternal age alone. The aim of this comparative review was to summarize and compare the existing recommendations on IPDT from the most influential guidelines. Definite prenatal diagnosis is only possible by invasive prenatal diagnostic testing (IPDT), mainly including amniocentesis and chorionic villous sampling (CVS). Sophisticated screening protocols for genetic abnormalities constitute an important component of current prenatal care, aiming to identify high-risk pregnancies and offer appropriate counseling to parents regarding their options.
