Biochemistry at the North Devon District Hospital

This department is both extensively automated and computerised.  The benefits are reliable assays, large throughput and fast return of results.

The majority of results are returned within one working day. Exceptions include some hormone assays which are batched before testing and those specialized requests sent to accredited regional laboratories.  Should you be worried by a delay please ring EXT 2345.

The laboratory provides a wide range of assays locally but refers, to specialist accredited departments, those rare or expensive tests which are best dealt with in tertiary centres.
Good communication is the key to success and this means we need to know by telephone when special or urgent requests are likely to be asked for.

Please try to make a point of coming to the laboratory at some time to meet the staff.
