Combined test

The Combined Test is a test that combines, with the use of specific software, Nuchal fold thickness measurement with the Double Marker Test, taking into consideration the foetal crown to sacrum length and the mother’s age, in order to calculate a risk index for the three most common chromosomal anomalies (trisomy 13,18 and 21).

Analysing the result of the combined test can make it possible to identify, with approximately 90% accuracy, foetuses with chromosomal abnormalities, in order to allow a more specific use of invasive prenatal diagnostic techniques, Chorionic villus sampling and Amniocentesis. Altered combined test values can also be observed in the presence of certain foetal abnormalities (cardiac especially) or high obstetric risk.
