Role of the Laboratory and its integration
The
medical laboratory is one of the cornerstones of modern medicine. Clinical
laboratory tests have become a key in most diagnostic procedure. The laboratory
has an important role in improving the health care system by maintaining.
# Quality
# Efficiency
# Cost effectiveness.
# Planning and management in health care system,
A. Laboratory can improve the quality of health care system by following ways:
>Laboratory
investigations increases the accuracy of disease diagnosis and thus lead to>
-Correct treatment with
reduction of misuse and waste of drugs.
-Decrease morbidity and
mortality.
-Increase confidence
and motivation of health personnel.
>The laboratory has an
essential role in screening for ill health and assessing response to treatment
>Laboratory is needed
to work with other in reducing infection in the community and investigating
epidemics rapidly.The function of health
laboratory service includes:
-Detecting the source
of infection, identifying carriers and contact teaching.
B. Laboratory can contribute to achieve efficiency and cost effectiveness in health care system by following ways:
>The
laboratory can help to reduce expenditure on drugs. After getting
laboratory investigation reports the accuracy of diagnosis improves.
>The
laboratory can lower health care cost by identifying disease at an Charley
stage.
>Significant
savings can be made when the laboratory participates in local disease
surveillance and control.
>Laboratory
provides information to achieve national health planning and good health management.
