PRISCA – A Computer Program for Calculating Fetal Abnormality Risks
PRISCA is a computer program designed to calculate the risks of possible fetal abnormalities. For more accurate information, it is optimally conducted in the first trimester between weeks 11 and 13, with an interval of 6 days.
Tested Parameters
- Free Beta-hCG
- PAPP-A test
What Does PRISCA Determine?
- Down Syndrome (Trisomy 21) – The risk of fetal development increases proportionally with maternal age.
- Edwards Syndrome (Trisomy 18) – The survival rate for affected infants is 10%, with 90% dying within the first year.
- Patau Syndrome (Trisomy 13) – Severe abnormalities affecting multiple organs in the fetus.
- The analysis is performed on a blood sample taken from a vein.
- The test must be taken on an empty stomach.
- A recent ultrasound scan (conducted within the last 24 hours) is required for PRISCA calculations.
- First-trimester screening for fetal chromosomal abnormalities
- Detection of fetal abnormalities through ultrasound examination
- Deviations in biochemical markers during prenatal screening
- Justification for invasive prenatal diagnostics
Results are presented in the form of a graph, where individual risk levels are indicated separately.
- High risk:≤1:250
- Moderate risk:1:251–1:1000
- Low risk:≥1:1000
