Timely identification of FH\u20101 is important because of an increased risk of vascular events in affected individuals and because it provides the opportunity to guide appropriate treatment. Genetic testing is recommended if onset is at a young age (&lt;20\u2009years), there is a family history of PA or early cerebrovascular events occur.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aims<\/jats:title><jats:p>To assess national rates of testing for FH\u20101, whether this varied over time and by region.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>De\u2010identified data were obtained on genetic testing performed for FH\u20101 from 1 April 2010 to 30 October 2023 (163 months) from the Canterbury Health Laboratories database, the sole national testing laboratory for FH\u20101.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 147 tests were performed, of which 19 (12.9%) were positive.
