    My contribution to clinical science has centered on quality assurance of clinical genetic testing.  I am a passionate advocate of quality laboratory testing and have written international guidelines for analytical validation. In order to ensure quality in genetic testing, reference materials are needed for clinical laboratories.  Clinical laboratories often use genomic DNA samples, either from cell lines or residual de-identified patient material, as reference materials.  This lack of reference materials hinders the ability of laboratories to develop and validate assays and perform necessary quality control.  It also makes comparison of assays and standardization between laboratories difficult.  I have been involved and led several efforts to characterize reference materials. Considering the complex nature of clinical testing and interpretation, and its impact on patient care, there is a practical need for standardizing clinical assays. Standardized test panels developed for clinical assays could also facilitate clinical implementation of genomic tests. Such standardized could enable physicians, researchers and other stakeholders to understand genetics test results without extensive scrutiny of the alleles included in the assay, and provide assurance that clinical laboratory panels include a minimum set of clinically relevant variants. The policy issues for the development, validation and clinical implementation of genetic biomarkers presents a number of challenges. First, there is significant uncertainty in the regulatory framework for biomarker tests. Second, there is concern over the adequacy of the current oversight of laboratories conducting biomarker testing. Third, there is a lack of alignment between the processes for regulatory and reimbursement decisions. All these challenges cause uncertainty and confusion among clinicians, patients, test manufacturers, and payers.  I have been an active advocate for appropriate clinical testing and reimbursement.
