Genetic Units (GenUs)

All NHS services are required to return data on service activity in order to inform contracts and future developments.  The UKGTN, in collaboration with professional organisations, has developed the Genetic Units (GenUs) system for laboratories to record and submit data consistently.  A summary of the development process is available here.

The system is based on allocating genetic testing reports to one of a number of weighted bands.  The bands are labelled A to H and the weight of each band is the GenU score.  Band A currently has a weight of 1 GenU and band H a weight of 40 GenUs.  

Each sample received by a laboratory where DNA is extracted will be allocated a band A to account for the work involved in preparing a sample for testing.  The laboratory then records the number of reports per band based on the tables and instructions provided.

Instructions for use

The current version of GenUs was approved in early 2016 and is referred to as the 2016 version.  It should be used for recording activity from April 2016.  Previous versions of the system were approved in 2014 and 2012. 

Quality Reviews

The UKGTN reports on the use of GenUs in member laboratories using information submitted as part of UKGTN Annual Returns and from data submitted as part of the UK external quality assessment schemes for both molecular and cytogenetics.
