| Popis: | Genetic investigations are becoming increasingly useful and widespread in many areas of human health. However, there is a worldwide lack of certified reference materials for use in genetic testing, meaning that tests are being run without well validated controls and new assays are more difficult to develop and validate. We have responded to this challenge by starting a programme of developing genetic reference materials (GRMs) for international accreditation and worldwide distribution. Our approach has been to make materials for disorders where testing is commonplace and genotyping errors have been demonstrated. To ensure a continuing supply of DNA, cell lines are established from consenting, phenotypically well-characterised patients and are then grown up in bulk for genomic DNA extraction to yield up to 100 milligrams of DNA. In most cases the DNA is then formulated, freeze-dried and sealed in glass ampoules to ensure greater stability over time and obviate the need for chilled transportation. In this paper we explore the options and routes available to the production of DNA reference materials and describe the establishment of the first internationally recognised reference materials for human genomic DNA, with particular reference to some genetic tests carried out frequently within haematological and cardiovascular laboratories. |
