Requests for investigations
All requests should be made using the hospital computer system.
This is the Integrated Clinical Environment (ICE). For those areas
not covered by ICE, the pre-printed biochemistry request form
should be used, with patient labels if possible. Downtime forms for
CMFT staff are available on the intranet.
All samples and request cards should have as much information on
as possible to enable us to positively identify the patient that
the sample has come from, to ensure that the sample and card relate
to the same person and to identify which tests need doing and any
For some assays it is essential that we know the time that the
sample was taken. This is especially important in the case of
therapeutic drug monitoring. It is preferred that samples are
labelled with pre-printed labels from ICE or from the patient's
notes. If handwritten the tube should as a minimum be labelled with
surname, first name and hospital record number or other unique
identifier such as NHS number.
All requests must adhere to the Directorate of Laboratory
Medicine's Sample Acceptance Policy.
External laboratories are able to link to our information system
electronically to maximise efficiency of sample referral using the
NPex system (Lab2Lab).
