Participating laboratories unanimously expressed a willingness to adopt these data elements in their requisition forms. This study demonstrates the value of comparing and sharing best practices through an expert group, such as the ClinGen Program, to enhance variant interpretation, providing a foundation for leveraging cumulative case-level data in public databases and ultimately improving patient care.The most recent build of the human reference genome, GRCh38, was released in 2013. However, many laboratories performing next-generation sequencing (NGS) continue to align to GRCh37. Our aim was to assess the number of clinical diagnostic laboratories that have migrated to GRCh38 and discern factors impeding migration for those still using GRCh37. A brief, five-question survey was electronically administered to 71 clinical laboratories offering constitutional NGS-based testing and analyzed categorically. Twenty-eight responses meeting inclusion criteria were collected from 24 academic and four commercial diagnostic laboratories. Most of these (14; 50%) reported volumes of less then 500 NGS-based tests in 2019. Only two respondents (7%) had already migrated entirely to GRCh38; most laboratories (15; 54%) had no plans to migrate. The two prevailing reasons for not yet migrating were as follows laboratories did not feel the benefits outweighed the time and monetary costs (14; 50%); and laboratories had insufficient staff to facilitate the migration (12; 43%). These data, although limited, suggest most clinical molecular laboratories are reluctant to migrate to GRCh38, and there appear to be multiple obstacles to overcome before GRCh38 is widely adopted. Adolescents face many barriers to obtaining emergency contraception (EC), despite it being an approved and recommended method to prevent unintended pregnancy. This study examined pharm
