# Prenatal Screening, Bulevardi 22 Keywords: - [prenatal diagnostics](< /en/search?q=prenatal diagnostics >) - [ultrasound examination](< /en/search?q=ultrasound examination >) If you are pregnant, you are entitled to two ultrasound examinations free of charge. We aim to schedule the early pregnancy ultrasound scan on gestational weeks 12+0–13+3 and the morphology ultrasound scan on gestational weeks 20+0–21+3.  The ultrasound examinations are voluntary. In the early pregnancy ultrasound examination, it is also possible to perform a nuchal translucency scan associated with chromosomal aberrations of the fetus, as well as take a blood sample. In some of the high-risk pregnancies, the examinations are carried out by a specialist, in which case a fee will be charged for the appointment. The duration of the screening scan is 30 minutes. We train future health care professionals in our unit. We hope that you will allow students to participate in your care. Consenting or refusing student participation will not affect your care. ## Arrival instructions --- - Barrier-free entrance is via the courtyard. #### Public transport - Our unit is easy to reach with public transport.
