Description

PRISCA is a second-trimester fetal chromosomal abnormality screening test. The optimal time is 16-18 weeks. Based on β-hCG, AFP, and free estriol levels, the system calculates the risk of trisomies (21, 18, 13). It is recommended for pregnant women with identified risk factors after the first trimester.

PRISCA II Trimester is a non-invasive prenatal test that calculates the individual risk of developing chromosomal abnormalities in the fetus. The calculation is performed using the PRISCA (Prenatal Risk Calculation) computer program, which takes into account the patient's laboratory parameters and clinical data.

The test includes the determination of three biochemical markers:

  • free β-subunit of human chorionic gonadotropin (β-hCG);
  • alpha-fetoprotein (AFP); and free estriol.

The optimal time for testing is 16-18 weeks, within the acceptable period from 14+0 to 21+6 weeks.

PRISCA II is used to assess the risk of chromosomal abnormalities such as trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome), and trisomy 13 (Patau syndrome). The test is recommended if risk factors or abnormalities are identified based on first-trimester screening results.

When and who needs the test?

  • Pregnant women in the second trimester (14+0 – 21+6 weeks) who have been identified as at risk based on first-trimester screening or clinical indications.
  • Women aged 35 years and older.
  • If ultrasound markers or abnormalities are detected in the first trimester.
  • If there is a history of chromosomal abnormalities in previous pregnancies.
  • If there are hereditary risk factors for chromosomal pathology in the family.

Biological material

  • Venous blood

Preparing for a blood test

In order to exclude factors that may affect the test results, we recommend to follow the preparation rules:

  • an important condition for laboratory tests is to take blood on an empty stomach;
  • 6-12 hours before the test, you should avoid eating, drinking alcohol, smoking, and limit physical activity. Drinking...
