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:
Platelets are a key cell in the Haemostatic system and adequate numbers of functional platelets are required for normal Haemostasis. The platelet count is used as part of a screen when easy bruising/bleeding is suspected or where numbers may be increased leading to thrombotic risk. It may also be used to follow the progress of therapies which may reduce numbers (chemotherapy). Platelet numbers may be reduced in a number of disease states including Leukaemia, ITP, TTP and other bone marrow failures. The platelet count does not measure platelet function
