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.
Please call 301-519-2100 or email prenatal@genedx.com in advance to discuss prenatal cases.
All prenatal tests will have maternal cell contamination (MCC) studies performed as a part of the test. Send a maternal blood or buccal specimen for comparison. Other relatives’ specimens may also be required.
Labeling
Label with the patient name plus a second identifier such as date of birth, specimen ID or medical record number. Name and 2nd identifier on the specimen label must match what is on the test order. If the tissue source is Product of Conception (POC) state this clearly on the label and state whether the tissue was fetal or placental in origin.
Kits
Complimentary prenatal kits are available for US and Canadian clients. To order prenatal kits for amniotic fluid samples, please visit our request supplies page or email support@genedx.com.
To order kits with media for CVS or POC samples, please email support@genedx.com or prenatal@genedx.com.
Stability
Cultures must be topped off with sterile media immediately before shipping. All specimens, including Placental POCs will be tested for maternal cell contamination (MCC). Send a maternal blood or buccal specimen for comparison. Other relatives’ specimens may be required. If the tissue source is products of conception (POC) state this clearly and state whether the tissue was fetal or placental in origin. Placental POC cultures require maternal cell contamination testing and a maternal blood or buccal specimen is required for comparison.
