Advice on the diagnosis, treatment and containment of viral infections in patients is available at any time through the 24 hour consultant led clinical service. Outside laboratory working hours, the virologist on call can be air-called via the UCLH Switchboard.

Requests for the provision of laboratory tests outside normal working hours may be accommodated under certain circumstances. These should be arranged with the medical virologist on-call who may be air-called through the UCLH switchboard.
