    Prenatal screening, conducted in the I-II trimesters of pregnancy, refers to the methods of examination, allowing in the early stages of pregnancy to conduct a comprehensive assessment of fetal development and timely identify the risk of abnormal development of the fetus and the birth of a child with chromosomal disorders.

    Full screening of the first two periods of pregnancy includes:

    • Prenatal screening for the first trimester at 11 weeks – 14 weeks of pregnancy (according to the last menstruation date). Includes ultrasound (markers of the first trimester are the presence of a nasal bone, coccyx parietal fetal size and thickness of the collar space) and biochemical screening – a double test that includes a blood test for human chorionic hormone (HCG) and plasma protein A (Papp-a).
    • Prenatal screening of the II trimester (from the 16th to the 20th week of pregnancy). Includes ultrasound (allows you to study in detail all the systems and organs of the child, to exclude most of the developmental anomalies of the fetus – cardiovascular and urinary system defects, musculoskeletal system, face and brain) and a triple biochemical test (blood test for hCG, alpha fetoprotein (AFP) and free estriol).
    • Computer processing of the obtained results and calculation of genetic risk taking into account many factors (woman’s age, the presence of chronic diseases, weight, hereditary diseases in the family, the presence of toxicosis). It should be understood that the results obtained determine only the probable risks and are not a basis for making a diagnosis. However, if there is a high risk of developing pathology, a consultation of genetics is appointed and, if necessary, additional research.
