Central Nervous System (CNS) Device

Any device that is introduced into the central nervous system is a potential source of infection. These devices can be cultured for bacteria and fungi.

Sample type

Shunt reservoir
Shunt tubing
Epidural tips
Other central nervous system devices e.g. bolts and electrodes

Specimen requirements

Devices should be sent in an appropriate CE marked leak-proof container. Ideally, devices should be collected prior to the start of antimicrobial therapy.

If a shunt is completely removed, it is desirable that all three portions of the shunt are sent in separate containers and labelled clearly i.e. long end, short end and reservoir / valve.
