If QF-PCR is done at an external centre:
Referring Center must fax RAD results ASAP to MSH (fax: 416-586-8395)
Note: Microarray will only be initiated upon receipt of QF-PCR results.
1. If QF-PCR results are normal then microarray is performed and reported to referring center.
2. If maternal cell contamination is detected then referring center will be notified to send cultured cells to MSH for microarray.
