FAQs for Molecular Pathology

What specimen type is required for laboratory tests?

One whole blood EDTA (lavender) tube is sufficient for genetic tests. These include cystic fibrosis, factor V Leiden, prothrombin, methylenetetrahydro folate reductase, hemochromatosis, Y chromosome deletion, fragile X, and Prader-Willi/Angelman syndrome. One whole blood ACD (yellow) tube is also acceptable. The specimens should be kept at room temperature.

One PPT (ivory) tube is sufficient for viral load testing. These include HIV, HBV, HCV, CMV and BKV. The specimens should be spun within two hours of collection. HIVs, HBVs and HCVs should be frozen and CMV and BKV should be kept at room temperature.

Three EDTA (lavender) tubes should be drawn for BCR/ ABLs. The specimen should be transported to the molecular pathology lab within three hours of collection to preserve the RNA. Please call the Molecular Pathology Lab at 704-304-5744 to arrange for a courier. 

BCR, TCR and BCL2 can be submitted as paraffin tissue, fresh tissue or whole blood collected in an EDTA (lavender) tube.
