Serious problems with blood tests in South East London

Posted on:

July 16th Update: Right now, we still can’t order many blood tests.

Blood testing services are still severely affected by a cyber-attack that happened in June, across South East London.

We are only able to order the most critical blood tests for very concerning conditions.

We understand this is very difficult for everyone and we will keep you updated on this page as we know further details.

Thank you for your patience.


On Monday 3 June Synnovis, a provider of lab services, was the victim of a ransomware cyber attack.

This is having a significant impact on the delivery of services at Guy’s and St Thomas’, King’s College Hospital NHS Foundation Trusts and primary care services in south east London and we apologise for the inconvenience this is causing to patients and their families.

Emergency care continues to be available, so patients should access services in the normal way by dialling 999 in an emergency and otherwise using 111, and patients should continue to attend appointments unless they are told otherwise.

We will continue to provide updates for local patients and the public about the impact on services and how they can continue to get the care they need. The local NHS have set up a webpage where the latest updates will be posted.
