Changes to Biochemistry Phone Limits
From Monday 17th June the Biochemistry phone limits at Heartlands/Good Hope and Solihull will change (see table below). The new limits are already in place on the Queen Elizabeth site and so we will now be phoning the same results across all sites. The new limits reflect changes to the Royal College of Pathologists guidance.
