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:
G-banded metaphase chromosome analysis (karyotyping) can identify genome-wide structural chromosome abnormalities including balanced translocations, inversion and can identify genomic complexity in living cells actively undergoing mitotic division. Karyotyping is vital in many haematological malignancies especially in myeloid malignancies where karyotype analysis is vital for prognosis and treatment decisions. Karyotyping will usually be performed on a bone marrow aspirate sample on request of a consultant or specialist registrar in haematology.
