Methodology Matters: A comparative study of whole-genome sequencing (WGS) and single-nucleotide polymorphism (SNP) Methods
Live Counsyl Webinar - Wednesday, July 19, 2017
Two time slots are available: 9am PDT (12:00pm EDT) or 12:00pm PDT (3pm EDT)

Join this 30 minute webinar to learn about the clinical consequences of ordering a non-invasive prenatal screening (NIPS) test that uses WGS versus the SNP method, based on findings from a recent study published in Prenatal Diagnosis.(1) 

Authors of the paper will discuss the key differences between the two NIPS methods and how these result in substantial implications for you and your patients.


You will discover:

  • How NIPS sequencing methodology impacts detection of aneuploidy in low fetal fraction samples

  • How each method is affected by the origin of aneuploidy (egg or sperm)
  • How each method impacts false negatives and invasive procedures
  • How these differences affect your patients and your clinic's workflow

At Counsyl, we strive to put patients first, put clinicians in control, and put costs in their place. Since 2007, we’ve worked with tens of thousands of providers to screen over half a million patients. 


Our DNA tests include:
Family Prep Screen: Detect more at-risk couples with expanded carrier screening
Informed Pregnancy Screen: Clarify true risk in non-invasive prenatal screening
Inherited Cancer ScreenIdentify more patients at elevated risk for hereditary cancers
