Four departments, closer up.
Haematology
Our haematology unit runs on a 5-part differential analyzer that flags abnormal cell populations automatically, so nothing gets missed between the sample and the pathologist's eye. Every flagged smear is reviewed manually under the microscope before a report leaves the lab.
