Treatment and study plan

Primary outcomes

  1. Clinical Assay Performance

    Time frame: Performance of the assay will be based upon a single blood sample collected during the only study visit from a high risk pregnancy prior to the subject undergoing an invasive procedure (amniocentesis or CVS) to confirm fetal karyotype.

    Each subject will provide a single blood sample prior to undergoing an amniocentesis/CVS that will be processed to plasma and stored frozen until the end of the study. Frozen plasma samples will then be analyzed using the SEQureDx Trisomy Test and the sensitivity and specificity of the assay will be determined by comparing the plasma test results to the fetal karyotyping results obtained via aminiocentesis or CVS. A subject's participation ends after the results of the fetal karyotype are obtained and recorded.

Secondary outcomes

  1. Subject selection bias assessment

    Time frame: A single blood sample will be collected at a single clinic visit from high risk pregnancies that refuse to undergo an invasive procedure.

    All subjects that enter the study are at high risk for fetal aneuploidy. However, sensitivity and specificity of the assay will be based upon those subjects that have a confirmed fetal karyotype obtained by amniocentesis/CVS. Subject selection bias assessment will be done by comparing SEQureDx Trisomy T21 Test results between women who agree to undergo an invasive procedure to obtain fetal karyotype and women who elect not to undergo an invasive procedure.
