Additional Specimen Information
This genetic test needs nucleated cells. Please don’t centrifuge or freeze the EDTA blood tube.
If storing blood tube prior to delivery please refrigerate at 4 degrees (transport at ambient temperature).
An aliquot of DNA extracted by another accredited diagnostic laboratory is also an acceptable sample type. DNA extracts should be 50 ng and of adequate quality for testing with an A260/A280 ratio of 1.8, and an A260/230 ratio greater than 2.0. Please contact the laboratory to discuss specific requirements if the available DNA does not meet these standards.
