Background: Domestic and international acts of terrorism using chemicals an
d pathogens as weapons have recently attracted much attention because of se
veral hoaxes and real incidents. Clinical laboratories, especially those af
filiated with major trauma centers, should be prepared to respond rapidly b
y providing diagnostic tests for the detection and identification of specif
ic agents, so that specific therapy and victim management can be initiated
in a timely manner. As first-line responders, clinical laboratory personnel
should become familiar with the various chemical or biological agents and
be active participants in their local defense programs.
Approach: We review the selected agents previously considered or used in ch
emical and biological warfare, outline their poisonous and pathogenic effec
ts, describe techniques used in their identification, address some of the l
ogistical and technical difficulties in maintaining such tests in clinical
laboratories, and comment on some of the analytical issues, such as specime
n handling and personal protective equipment.
Content: The chemical agents discussed include nerve, blistering, and pulmo
nary agents and cyanides. Biological agents, including anthrax and smallpox
, are also discussed as examples for organisms with potential use in bioter
rorism. Available therapies for each agent are outlined to assist clinical
laboratory personnel in making intelligent decisions regarding implementati
on of diagnostic tests as a part of a comprehensive defense program.
Summary: As the civilian medical community prepares for biological and chem
ical terrorist attacks, improvement in the capabilities of clinical laborat
ories is essential in supporting counterterrorism programs designed to resp
ond to such attacks. Accurate assessment of resources in clinical laborator
ies is important because it will provide local authorities with an alternat
ive resource for immediate diagnostic analysis. It is, therefore, recommend
ed that clinical laboratories identify their current resources and the exte
nt of support they can provide, and inform the authorities of their state o
f readiness. (C) 2000 American Association for Clinical Chemistry.
