: EDTA and ACDH tubes - Room temperature: 2 days Refrigerated: 3 days; Purified DNA - indefinitely @ -70°C; Paraffin block - indefinitely; Chorionic villi and cultured cells - call Molecular Diagnostics Lab at 615-343-8121
Reasons for Rejection
: Decalcification (paraffin embedded tissue) Client will be notified by Molecular Diagnostics Lab if specimen is rejected.
: Monday - Friday
: 5 - 7 days
: Call the Molecular Diagnostics Laboratory at 615-343-8121 if additional assistance is needed regarding specimen requirements or submission. Please notify Molecular Dagnostics Laboratory if patient has received a transfusion in the prior 2 weeks. Chorionic Villi must be free of maternal cells; Cultured cells - backup culture must be maintained in event additional DNA is required.
