Blood transfusion

Arrow In this section

The results availability times given here represent the time generally required to produce a result following receipt of the sample in the laboratory. Sample transport times are not included.

Where appropriate, if a result is required the same day samples must be received sufficiently early to allow completion of the test. Contact the lab if the test you require is not listed.

These tests are available during the normal working day. See a list of haematology tests available outside core working hours.

For further advice or information, call 0161 276 4400 or 64887. For urgent requests for blood transfusion, call 0161 276 4400.
