This item was just covered on the BBC news for the south-east.
Nearly 2,500 patients have been recalled for extra tests after problems with a merged pathology service between Medway Foundation Trust and Dartford and Gravesham Trust.
Issues included blood samples being delayed for so long they could not be analysed and 600 samples being rejected in the first week after services transferred to the merged service.
No evidence of clinical harm has been found so far but the delays are being treated as a serious incident, and NHS England and NHS Improvement have been informed.
Despite these issues, they are apparently still mean to go ahead with plans to amalgamate pathology across all of the Kent & Medway area. I don't know whether other counties propose similar changes, but no doubt 'lessons will be learnt'!
