About Our Fragile X Carrier Testing

Note: Fasting is not required for this test.

This XSense® blood test is used in the determination of fragile X status (affected or carrier) of the fetus. Fragile X syndrome is a genetic condition that causes a range of developmental problems including learning disabilities and cognitive impairment.

This test is recommended when an affected or carrier individual has already been identified in the family.

This test is also used in the determination of fetal karyotype and prenatal diagnosis of Down syndrome or other chromosomal abnormalities. Also includes analysis of midtrimester amniotic fluid for detection of open neural tube defects.


Neural tube defects are birth defects of the brain, spine, or spinal cord.

Down syndrome is a genetic chromosome 21 disorder causing developmental and intellectual delays.
