Introduction: Each person should have a minimum of 12 examinations during pregnancy. The initial examination should be done by the 12th week of pregnancy. Various invasive and non- invasive diagnostic procedures are performed, such as amniocentesis, amnioscopy, ultrasound, CTG, biopsy of chorionic villi and cordocentesis. Subjects and methods: In the prospective study, an anonymous survey questionnaire was used, which randomly selected 113 adult subjects of both sexes. Results: A statistically significantly higher number of respondents stated that the prenatal diagnostic procedure was performed for all of the stated reasons, compared to the number of respondents who stated individual reasons (χ2= 4.923; p= 0.027). Statistically significant differences were found in the number of respondents regarding the most well-known prenatal diagnostic procedures (χ2= 28.452; p< 0.001), the largest number of them mentioned amniocentesis, and the smallest number mentioned cordocentesis and biopsy of chorionic villi. Conclusion: It can be concluded that the respondents are well acquainted with prenatal diagnostic procedures, but of course there is always room for improvement of this knowledge, which can certainly help the respondents to understand even more the importance of these procedures and the benefits they bring with them.
