Summary In the following paper we have presented the results of non-invasive and invasive prenatal diagnostic tests performed on 2285 pregnant women from the Western-Pomeranian Region between 2005 and 2006. Material and methods: Retrospective analysis of screening tests on 2285 pregnant women. Medical history, including age, weight, familial data pedigrees up to third degree relatives, accompanying diseases, gestational complications in the family, type, dosage and period of any drugs intake, was obtained. Sonographic screening and evaluation of maternal serum PAPP-A and betaHCG levels. Results: Screening tests identified 4.5% high-risk pregnancies in this group. 69% of the patients consented to invasive diagnosis. As a result, genetic anomalies were detected in 43.7% of cases. Significant differences in betaHCG levels correlated with oral gestagens intake and place of residence (coastal areas). Conclusion: Broad use of certified non-invasive methods of prenatal screening allow substansial reduction of invasive procedures with high levels of positive prediction. Medical drugs intake as well as place of inhabitation may influence on free betaHCG levels.
