Test Name:Telomere MLPA
Test Code:CERNER: MDLBL-;APPEND TEST NAME AND SPECIMEN TYPE
Performing Site: Alberta Children's Hospital
Performing Dept:Molecular Diagnostics
 
TAT:6 - 8 weeks
 
Preferred Tube/Container:See Specimen Requirements
 
Specimen Requirements:Whole blood specimen is the preferred specimen type for tests performed using MLPA methodology.

For Blood Specimen (peripheral or cord blood)
  • For Patients >20 kg - Collect 2 EDTA tubes each containing 3.0 to 5.0 mL of blood
  • For Patients <20 kg - Collect 2 EDTA tubes each containing 2.0 to 3.0 mL of blood
  • For Neonates           - Collect 1 EDTA containing a minimum of 0.5 mL of blood

    For Prenatal Specimens
    Submit in a sterile 15 mL or 50 mL polypropylene centrifuge tube or in a plain sterile tube with screw cap
  • For Chorionic Villi specimens -  Submit a minimum of 15 mg
  • For Amniotic Fluid specimens - Submit a minimum of 25 mL
    NOTE: A maternal blood sample (as outlined above) must be collected for maternal cell contamination studies.

    For Other Tissue Specimens
  • For Fresh or Frozen Tissue specimens - Submit > 20mg in a sterile container with NO fixative.
  • For Cultured Cells                                    - Confluent (overgrown) T25 flask (or equivalent)
                                                                              placed in transport media.

    For Extracted DNA
  • Submit 10ug @ >100ng/uL
    •  
    Min. Sample Required:If unable to collect the minimum as per specimen requirements, contact the laboratory.
     
    Specimen Processing:Unopened dedicated tubes (do not share) are required for Molecular Diagnostic Laboratory testing.
    Do not spin or aliquot specimens.

    For all specimen types (except frozen tissue) store specimens at ambient temperature if being shipped on same day of collection (preferred). Specimens can be stored at 4 - 8oC if shipping is delayed.

    Store frozen tissue specimens at -20oC to -80oC.
     
    Specimen Handling:Transport all specimen types (except frozen tissue) at ambient temperature.
    Specimens must not freeze in transit.

    Transport frozen tissue specimens with adequate amounts of dry ice to keep specimen frozen.
    Specimens must not thaw in transport.

    Specimens, with completed requisitions, should be received by the Molecular Diagnostic Laboratory:
  • Within 5 days of date of collection for Blood and Extracted DNA specimens.
  • Within 24 hours of date of collection for Amniotic Fluid, Chorionic Villi and Tissue specimen types.

    Ship specimens to Molecular Diagnostic Laboratory at Alberta Children’s Hospital Room B0-020.
    •  
    Requisition/Form:All requests MUST be submitted on a Molecular Diagnostic Laboratory Requisition.

    Please ensure all required information, including patient's clinical history/indication, is provided on the requisition.
     
    Method:MLPA
    Method Details:Detects deletions and duplications
     
    Reference Interval:Interpretation provided on report.
