===Laboratory Tests===

In the United Kingdom, bluetongue is a notifiable disease and so samples from suspected cases should be submitted to the Institute for Animal Health (Pirbright) for laboratory diagnosis. Samples are collected from sheep with raised temperatures and include jugular blood collected into a plain tube to provide serum for an antibody test, and a heparinised blood sample to be used for PCR. Serum from in-contact ruminants is also submitted, as well as spleen and lymph node from all post-mortem cases. All samples should be stored at 4°C and never frozen.
