Sample Requirements


We are able to perform testing on:
  • Whole blood (in EDTA)
  • Chorionic villi and cultured chorionic villus cells (submitted with maternal blood for maternal cell contamination studies)
  • Cultured amniocytes (submitted with maternal blood for maternal cell contamination studies)
  • Frozen, unfixed tissue
  • DNA extracted by a CLIA certified laboratory ONLY if there is no other sample available or obtaining another sample would present extreme hardship for the patient. Please call the laboratory to discuss.

If this is a prenatal study,
1) We
require a sample of maternal blood (5-10 cc in a lavender tube) to rule out maternal cell contamination. 

2) We require that a back-up culture be maintained elsewhere until testing is complete.

Please Note We require 2 patient identifiers on both the sample and the paperwork submitted with the sample.  The patient name and date of birth are preferred, but an internal identifier like specimen ID or medical record number may also be used.  We are not able to test samples that are not properly identified.
