In order to ensure 2023 billing, testing must be activated before the end of the year, or within 30 days of proband sample collection (if sample was collected in 2023). For Exome, Genome, or Xpanded testing, if you do not expect parental samples to be received in time for testing to be activated with 2023 billing, please contact us at support@genedx.com to determine how to proceed.

Testing that has been discontinued and replacement options available:

Discontinued TestReplacement Test Option
Rapid Aneuploidy FISH (3582)No other rapid test, however, FISH is considered a screen and microarray (460/410) is a diagnostic test that provides information on aneuploidy or other copy number variants.
Amniotic Fluid AFP (2122)No replacement
AChE (automatic reflex after AF-AFP) (1952-1)No replacement
Chromosome Analysis, Amniotic Fluid (2136)Micorarray (460/410). Microarray is a superior test for detecting copy number imbalances. It is not able to detect balanced structural rearrangements (translocations, inversions). FISH follow-up testing is available to interrogate for known familial rearrangements.
Chromosome Analysis, CVS (A587)Microarray (460/410)
Chromosome Analysis, Products of Conception (1053)Microarray (460/410)
Chromosome Analysis, Peripheral Blood (0559)Microarray (910)
Rule out Mosaicism, Chromosome Analysis, Blood (T982)Microarray is not ideal for low level mosaicism, if appropriate, FISH follow-up (J542) is the preferred test for mosaicism
