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 [email protected] to determine how to proceed.

XomeDxXpress® - Proband - Rapid Exome Sequencing

New York
Approved

Clinical Utility

  • Determination of a clinical diagnosis
  • Identification of gene implicated in genetic disease
  • Recurrence risk assessment

Lab Method

  • Next-Gen Sequencing

Based on current published guidelines, exome or genome sequencing can now be considered as first-tier tests for patients with unexplained epilepsy, developmental delay, intellectual disabilities and/or congenital anomalies.

Important Information

The XomeDxXpress® test is whole exome sequencing with an expedited turnaround time (TAT) of approximately 2 weeks. A provisional result is given within 7 calendar days after the start of testing and will include pathogenic and/or expected pathogenic variants in known disease-causing genes definitively explaining the patient’s phenotype. A written report including all clinically relevant variants will be reported within approximately 2 weeks after the start of testing. Because of the rapid TAT, samples on the proband must be submitted along with clinical information to begin testing.

Please email [email protected] to discuss prior to sending in samples.
