Valvekliinik – personalized care in the centre of Tallinn


The first-trimester screening, also called the OSCAR test, is recommended for all pregnant women between 11 and 14 weeks of gestation.

The OSCAR test assesses the risk of chromosomal disease and preeclampsia and monitors the anatomical development of the fetus.

The OSCAR screening is a combined test made up of two parts: a blood test and an ultrasound examination.

What kind of information is received from the OSCAR test?

  • Risk assessment of three chromosomal diseases – Down, Edwards, and Patau syndrome.
  • Risk assessment for preeclampsia. Preeclampsia is a disease in which the mother’s blood pressure rises in the second half of pregnancy, protein appears in the urine, changes in blood tests may occur and, in some cases, growth retardation may occur. It is possible to assess the risk of preeclampsia very accurately in the first trimester. If there is an increased risk, the woman can start prevention with aspirin.
  • OSCAR test also concentrates on examining the fetal anatomy, as different organ systems are already visible and their development can be assessed based on the size of the pregnancy.
  • It is possible to specify the due date. 

If the OSCAR test results show a high risk of chromosomal diseases, the woman is offered additional examinations. In some cases, a fetal cell-free DNA test, called the Niptify test, may be performed but it is often advisable to perform an invasive test, such as a chorionic biopsy or amniocentesis test. Invasive tests are performed in a hospital and referenced by the doctor who performed the OSCAR test.

You are welcome to OSCAR test alone or with a companion.
