[A consensus on the standardization of the next generation sequencing process for the diagnosis of genetic diseases (1) - Procedures prior to genetic testing].
2020
Pre-testing preparation is the basis and starting point of genetic testing. The process includes collection of clinical information, formulation of testing scheme, genetic counseling before testing, and completion of informed consent and testing authorization. To effectively identify genetic diseases in clinics can greatly improve the diagnostic rate of next generation sequencing (NGS), thereby reducing medical cost and improving clinical efficacy. The analysis of NGS results relies, to a large extent, on the understanding of genotype-phenotype correlations, therefore it is particularly important to collect and evaluate clinical phenotypes and describe them in uniform standard terms. Different types of genetic diseases or mutations may require specific testing techniques, which can yield twice the result with half the effort. Pre-testing genetic counseling can help patients and their families to understand the significance of relevant genetic testing, formulate individualized testing strategies, and lay a foundation for follow-up.
