How to order Sema4 Elements® Expanded Carrier Screening

When ordering a genetic screen, please include the appropriate test requisition and consent forms, along with your patient’s specimen. Multiple ordering and reporting options (EMR, portal, paper) are available.

Specimen requirements

  • Blood: Two 5-10 mL EDTA tubes (lavender top), and either a third 5-10 mL EDTA tube or one 5-10 mL ACD tube (yellow top)
  • Saliva: Saliva specimens are accepted in Oragene DNA (OG-500) kits by DNA Genotek. Please note that Tay Sachs enzyme analysis cannot be performed on saliva
  • If carrier screening was previously performed through Sema4, reanalysis and/or test enhancements may be ordered without providing an additional specimen. Please contact the laboratory to determine if an additional specimen is required
