To ensure that a patient’s test is billed to their 2024 health benefits, testing must be started before the end of the year. For exome, genome, or Xpanded testing, if you do not expect parental samples to be received before the end of the year, please contact us at support@genedx.com to determine how to proceed.
Other tissue types containing nucleated cells can sometimes be used for testing. Some tissue types are not recommended and will only be accepted in extraordinary circumstances with prior approval.
