Synnovis Blood Laboratory Cyber Incident - Update


NHS organisations across London continue to work in partnership to manage patient care following the ransomware cyber-attack on Synnovis earlier this week.

Guy’s and St Thomas’ NHS Foundation Trust, King’s College Hospital NHS Foundation Trust and South London and Maudsley NHS Foundation Trust remain in a critical incident, while Oxleas NHS Foundation Trust, Lewisham and Greenwich NHS Trust, Bromley Healthcare, and primary care services in South East London continue to be impacted.

NHS staff are working around the clock to minimise disruption to patient care following the ransomware cyber-attack on Synnovis. Unfortunately, some operations and procedures continue to be postponed, the majority of routine pathology tests have been postponed in primary care services in South East London.


Synnovis has informed us that a significant number of tests undertaken since 3 June have been cancelled. We apologise for any inconvenience and uncertainty caused by this. We will contact you if your test has been cancelled and needs repeating. Please note, however, that if your test is non-urgent or routine, all phlebotomy appointments for clinics which feed into Synnovis services have been postponed until the end of June. 

We will provide a further update as soon as one is available. We apologise to all those who have been impacted and staff will work hard to rearrange appointments and treatments as quickly as possible.

There is a page of frequently asked questions on the NHS Digital website which can provide more information.
