Reports from the Molecular Haemato-Oncology laboratory are fully integrated within APEX and are available electronically via APEX (Lothian users only) and TRAK.  For samples sent from out with NHS Lothian, paper copies of reports will be returned to the requesting laboratory, with the exception of BCR-ABL1 quantification for which results are emailed to the referring laboratory automatically.

The Department of Laboratory Medicine adheres to NHS Lothian’s Policy on Confidentiality of Personal Health Information, meaning that results can only be communicated to individuals authorised to receive them.

Communication of abnormal results to the requesting clinician: A member of the Molecular Haemato-Oncology Team will contact the requesting clinician via telephone or email to make them aware of clinically urgent results.

Expected turnaround times for each test, or panel of tests, are as follows:

 Quality Assurance

The Molecular Haemato-Oncology laboratory carries accreditation to international standard ISO15189:2022.  All investigations are subject to rigorous Internal Quality Control (IQC) measures and the laboratory participates in the following External Quality Assurance (EQA) schemes:

  • UK NEQAS Leucocyte Immunophenotyping Schemes
    • Myeloid Gene Panels (Pilot - Not Accredited)
    • BCR::ABL1 and AML Translocation Identification (assessed for PML::RARA; CBFB::MYH11 and RUNX1::RUNX1T1 analysis)
    • BCR::ABL1 Kinase Domain Variant (Mutation) Status
    • BCR::ABL1 Major Quantification [E13A2 & E14A2 fusion transcripts]
    • BCR::ABL1 Minor Quantification [E1A2 fusion transcript] 
    • FLT3 Mutation Status
    • IGH / TCR Clonality Status
    • KIT p.Asp816Val (D816V) Mutation Status for Mast Cell Disease
    • Lymphoplasmacytic Lymphoma / Waldenstrom Macroglobulinaemia [MYD88 p.L265P] 
    • NPM1 Mutation Status
    • Paediatric Acute Leukaemia Translocations (sssessed for ETV6::RUNX1; KMT2A::AFF1; TCF3::PBX1 analysis).
    • Measurable Residual Disease for AML by Molecular Methods (Pilot - Not Accredited) (assessed for PML::RARA CBFB::MYH11 RUNX1::RUNX1T1 and NPM1)
  • GenQA Schemes
    • Chronic Lymphocytic Leukaemia (CLL) IGHV mutation status
    • Chronic Lymphocytic Leukaemia (CLL) TP53 mutation analysis
    • Pathogenicity of haematological neoplasm variants (Classification only) (pilot)

Due to the rapid pace of developments in the field of molecular haemato-oncology, the laboratory may offer certain services before they have been accredited to ISO 15189:2022.  In all instances, relevant assays will have undergone a period of internal validation/verification and have been deemed suitable for diagnostic use prior to being offered to users.

The current accreditation status of individual tests can be found in relevant sections of our test directory and will always be clearly marked on any reports issued by the service.

Measurement Uncertainty

The impact and estimates of measurement uncertainty are determined for all relevant assays. These are available, on request to users.
