The briefing note Array CGH testing for learning disability: when is it worth it? presents the results of an economic evaluation comparing the costs and benefits of using array CGH as a first-line test for learning disability within NHS clinical genetics services.
Despite compelling evidence of the diagnostic benefits of using array CGH to diagnose learning disability the introduction of array CGH into routine first-line testing of learning disability has been hindered by the perceived high cost and complexity of the test and a lack of consensus on NHS service configuration across laboratories. This is despite the UKGTN approving the first-line use of array CGH for diagnosing learning disability, developmental delay and congenital anomalies for NHS use in 2012.
This briefing presents the results of an economic evaluation comparing the costs and benefits, as applicable to a NHS clinical genetics service, of using array CGH in a first-line setting with using it as a second-line test following a negative karyotype as the most appropriate comparator.
A paper from this work on the cost effectiveness of using array CGH for diagnosing learning disability has been published and is available at PubMed.
