Autosomal trisomies are among the most common chromosomal abnormalities detected during pregnancy and can significantly disrupt expected fetal development. Some trisomies are compatible with live birth but they are associated with serious developmental and medical complications, while many other chromosomal abnormalities are incompatible with life.
Accurate and timely diagnosis during pregnancy is therefore critical to support clinical counselling and informed pregnancy management.
Fetal DNA for analysis is obtained through sample collection via amniocentesis or Chorionic Villus Sampling (CVS), enabling confirmatory testing following high-risk screening results during prenatal/antenatal testing.
The Yourgene® QST*R range delivers rapid, reliable confirmatory detection of common aneuploidies using a panel of highly informative chromosomal markers.
Designed for diagnostic confidence, the single-tube assay utilises Quantitative Fluorescent Polymerase Chain Reaction (QF-PCR) technology, where fluorescent dye-labelled primers amplify highly polymorphic short tandem repeat (STR) regions on the chromosomes of interest.
The Yourgene QST*R Range assay detects:
The Yourgene® QST*R Base assay is a multiplex assay containing 22 markers across chromosomes 13, 18, 21, X and Y, enabling rapid confirmatory detection of common autosomal trisomies and sex chromosome aneuploidies.
The Base assay can be combined with our optional reflex kits, providing additional chromosomal markers for follow-up testing. This flexible approach supports comprehensive diagnostic coverage and delivers reliable results.
