A full blood count consists of haemoglobin, total white cell and differential counts, platelets and full red cell indices. All of these values are provided using a single EDTA sample. Please note that if venepuncture is difficult and mixing with anticoagulant delayed, micro-clot formation may cause a falsely low platelet count. If the full blood count results are abnormal or there is a specific indication on the request form, a blood film will be stained and examined microscopically.
This is the standard haematological inflammatory marker, performed in the laboratory, although CRP is the preferred test (Biochemistry request). The ESR may be performed on the same EDTA sample sent for FBC if sufficient.
The following referred tests should be requested on a Haematology request form and the Department will make arrangements to send the sample on.
The Department offers a comprehensive haemoglobinopathy screening service, however occasionally samples are referred for further analysis or confirmatory testing. Laboratory staff will refer samples if appropriate.

The Trust Laboratories at Heartlands Hospital, Good Hope Hospital and Solihull Hospital were awarded UKAS (United Kingdom Accreditation Service) accreditation to the internationally recognised ISO 15189 standard in May 2015. For a list of accredited tests and other information please visit the test database http://www.heftpathology.com/frontpage/test-database.html. Tests not appearing on this scope are either under consideration or in the process of accreditation and so currently remain outside of our scope of accreditation. However, these tests have been validated to the same high standard as accredited tests and are performed by the same trained and competent staff.
