Abstract:

Supplies for the diagnostic parasitology laboratory are often identical to those needed for routine work in other areas of microbiology. Biological hazards are best contained within a class IIA or class IIB biological safety cabinet (BSC). BSCs operate at a negative air pressure with air passing through a HEPA filter, and the vertical airflow serves as a barrier between the cabinet and the user. However, specific quality assurance recommendations within the parasitology section of microbiology have not been well defined in the past, and the information in this chapter should help clarify these recommendations. The procedure manual should contain for each test (i) the principle of the test; (ii) acceptable specimens (including rejection criteria) and instructions for proper specimen collection and processing; (iii) preparation of reagents and solutions; (iv) all supplies and equipment necessary to perform the test; (v) quality control (QC) procedures, results, and interpretation (including corrective action if QC is out of control); (vi) the test method; (vii) possible results; (viii) the correct way to report results; (ix) procedure notes (tips); (x) limitations of the procedure; (xi) additional tables and charts; and (xii) references. In the current environment of managed-care dominance within the United States, clinical laboratories continue to change their focus of operations and mission in response to the continually changing landscape. Traditional laboratories that are unwilling to change and adapt to this environment will probably not survive.
