Title: National Medical Laboratory Science Week 10th to 16th May 2004


1
National Medical Laboratory Science Week10th to
16th May 2004
  • An activity supported by the
  • Australian Institute of Medical Scientists
  • www.aims.org.au

2
National Medical Laboratory Science Week 2004
  • The National Medical Laboratory Science Week
    (NMLSW) is an annual activity co-ordinated by the
    Australian Institute of Medical of Scientists
    (AIMS) to promote the role of Medical
    Laboratories and their staff  in the maintenance
    of the health of the nation.

  • WHO ARE MEDICAL (LABORATORY) SCIENTISTS?Medical
    scientists perform medical laboratory tests on
    blood, other body fluids and tissues which assist
    clinicians in the diagnosis, treatment and
    prevention of disease. Medical scientists get
    results!

National Medical Laboratory Science Week 2004
  • WHERE DO MEDICAL SCIENTISTS WORK?Medical
    scientists work in hospital laboratories, private
    pathology laboratories, State Health laboratories
    and Universities.

National Medical Laboratory Science Week 2004
  • DISCIPLINESMedical Laboratory Science in
    Australia comprises many distinct professional
    disciplines. The main ones are
  • Histopathology Microbiology Cytology
    Blood transfusion Immunology Haematology
    Clinical biochemistry Virology

  • Microbiology
  • Identification of micro organisms such as
    bacteria, fungi, viruses and parasites which
    cause infection, and testing for effective
    antibiotics.

  • Haematology diseases and abnormalities of blood
    and bone marrow.Haematology medical scientists
    use automated instruments to count the numbers of
    red cells, white cells and platelets and then
    look at a thin film of the cells under a
    microscope.

  • Blood transfusion Laboratory testing of
    recipient blood and donor blood to ensure
    compatible and safe transfusion.Medical
    scientists in blood transfusion or
    immunohaematology, as it is sometimes known, are
    responsible for the testing of blood groups and
    compatibility of donor blood, prior to
    transfusion.

  • Histopathology Examination of the body cells
    and tissues to establish the presence or absence
    of disease.In Histopathology, medical scientists
    prepare tissues for light or electron microscopy,
    to detect abnormalities that may indicate cancer
    or other diseases of tissue.

National Medical Laboratory Science Week 2004
  • Clinical biochemistry Analysis of cells, blood
    and other body fluids for chemical, biochemical
    and hormonal components to identify disease or
    determine the effectiveness of a treatment
    regime.Medical scientists perform chemical
    analyses on body fluids to determine the presence
    of abnormal levels of the chemicals.

The scientific analysis of laboratory data is an
important part of biochemistry
11
National Medical Laboratory Science Week 2004
  • Virology Study of the consequences of viral
    infections.A scientist in a virology laboratory
    performs assays to detect the virus in host
    tissues or in cells used to isolate the virus
    from a host. These assays might detect viral
    nucleic acid or may involve immunological assays
    to detect viral proteins.

12
National Medical Laboratory Science Week 2004
  • Cytology Study of cellsMedical scientists in
    cytology are interested in individual abnormal
    cells, that are shed from tissues. One of the
    more publicised areas of their work is the
    Papanicolaou smear test (Pap Screen), which is
    used in the early detection of cancer of the
    cervix. After the sample has been collected onto
    a microscope slide, they are responsible for
    staining it and screening for abnormal cells.

Immunology A study of host responses to
infection, malignancy and tissue damage.A
medical scientist is able to identify and
quantitate cells involved in immune responses.
He/she is also able to identify and quantitate
blood proteins produced in response to infection,
malignancy or tissue damage or which play a role
in protecting the body against these changes. As
such an immunologist would diagnose, or assist in
the diagnosis of, bacterial viral and fungal
diseases, autoimmune diseases (e.g. rheumatoid
arthritis), hypersensitivity reactions (e.g.
asthma), cancer (e.g. leukaemia) or immunological
deficiencies in the host.
