Pre-testing Requirements
MLPA based assays are sensitive to the buffer used in DNA extraction processes. Due to this, our preference is to receive whole blood (EDTA) which will then be extracted at Canterbury Health Laboratories. Processing of DNA extracted at other centers may result in a request for a new sample if the analysis is compromised.
Additional Specimen Information
This genetic test needs nucleated cells. Please don’t centrifuge or freeze the EDTA blood tube.
Deliver same day or overnight courier, ambient.
While not our preference, an aliquot of DNA extracted by another accredited diagnostic laboratory is also an acceptable sample type. DNA extracts should be at least 20uL of DNA at a concentration no less than 20ng/uL. Please contact the laboratory to discuss specific requirements if the available DNA does not meet these standards.
