Any laboratorian who collects or handles tubes of blood is vulnerable (12).
Early surveys of LAIs found that laboratory personnel were three to nine times more likely than the general population to become infected with Mycobacterium tuberculosis (13,14).
This culture of safety is also supported by the Clinical and Laboratory Standards Institute (2). Bureau of Labor Statistics, in 2008, approximately 328,000 medical laboratory technicians and technologists worked in human diagnostic laboratories in the United States.
Work in a diagnostic laboratory entails safety considerations beyond the biological component; therefore, these guidelines also address a few of the more important day-to-day safety issues that affect laboratorians in settings where biological safety is a major focus. An estimated 500,000 persons in all professions work in human and animal diagnostic laboratories.
Reported parasite-associated LAIs were caused primarily by Leishmania, Plasmodium, Toxoplasma, Chagas disease organism, and other trypanosomes (20).
The Blue Ribbon Panel recommended that biosafety guidelines be developed to address the unique operational needs of the diagnostic laboratory community and that they be science based and made available broadly.
Throughout these guidelines, quality laboratory science is reinforced by a common-sense approach to biosafety in day-to-day activities.
Because many of the same diagnostic techniques are used in human and animal diagnostic laboratories, the text is presented with this in mind.
The attack rate in the general population aged 30–59 years (the estimated age range of the average laboratorian) was 0.3 per 100,000.
The attack rate for microbiologists (aged 30–59 years) was 20/100,000 (17).All functions of the human and animal diagnostic laboratory — microbiology, chemistry, hematology, and pathology with autopsy and necropsy guidance — are addressed.
