LABORATORY INFORMATION SYSTEMS
A laboratory information system (LIS) is a computer information system that
manages laboratory information for all the laboratory disciplines such as
clinical chemistry, haematology and microbiology.
Laboratory Information Systems provide modules for sending laboratory tests order to the instruments
through its multiple instrument interfaces, some are known as to have as many
as five hundred, track those orders and then capturing the results as soon as
they become available. The result can then be analysed and a report the
generated from it.
This report can be sent off for printing at a specific point, sent off to other
systems either to be added to patient’s electronic medical record or for
Laboratory Information Systems communicate with other information systems using clinical
information standard such as HL7. Laboratory systems might also make use of
LONIC (Laboratory Observation Identities, Names and Codes) to exchange
laboratory results with other systems.
Other features that include:
Patient management: Patient details like the admission date, admitting
physician, and admission number can be maintained by a Laboratory Information System. Other information
concerning the patient’s specimen including the ordering physician, department
ordering the test, specimen type, date/time of collection and receipt, and the
initials of the collecting technician, can also be managed in a Laboratory Information System.
Decision Support: Lab orders can be cross-referenced against classification
codes such as ICD-9 and LONIC, and also verified that that the correct test is
being carried out.
Patient Tracking: A patient tests can be catalogued and called up when the need
to review them comes up.
Quality Assurance: Ensures that the tests carried out using the currently
