Turnaround times
The quoted turnaround time is from sample receipt in the laboratory, to results authorisation in the Laboratory Information Management system. The times do not include transport of specimen to the laboratory or the administrative process to print and post/email reports. Service users must allow for transport and reporting time when ordering tests.
Clinical background:
Next generation sequencing is employed to look for variants in a range of genes all at the same time. These tests are requested by a consultant or specialist registrar in haematology or histopathology. These genomic changes can help in the diagnosis and prognosis of haematological malignancies. Analysis can be performed on tissue or liquid samples.
