Two Approved Immunology Guidelines
Guideline on Enzyme and Fluorescence Immunoassays
The National Committee for Clinical Laboratory Standards (NCCLS) has published two new guidelines, Glossary
The National Committee for Clinical Laboratory Standards (NCCLS) has published a new guideline, Enzyme and
and Guidelines for Immunodiagnostic Procedures, Reagents, and Reference Materials; Approved Guideline (Document DI l-A) and lmmunoprecipitin Analyses: Procedures for Evaluating the Performance of Materials, Approved Guideline (Document DI2-A).

These documents are the first approved guidelines in the NCCLS series addressing immunodiagnostic testing methodologies. DI1-A, which replaces the tentative edition (DI1-T) published in 1983, provides a common terminology and generic guidelines for the users and manufacturers of diagnostic test systems. DI2-A, which replaces the tentative edition (DI2-T) published in 1982, contains descriptions and procedures for evaluating the performance of materials used in immunoprecipitin analyses, and also includes discussions of the problems of specificity in the most widely used immunoprecipitin methods, necessary information for packaging inserts, and recommended reference preparations. An approved NCCLS document represents the consensus of the U.S. laboratory community achieved through the three-stage NCCLS consensus process.

document provides information on enzyme and fluorescence immunoassays to laboratory users and manufacturers of these systems. It describes the characteristics of the enzyme system, including the reagents and function tests, and the fluorescence system, including the various reagents. It also addresses the essential characteristics of the antibody and antigen, along with separation reagents in heterogeneous competitive immunoassays, instrumentation, and equipment, and other information on reagents. Manufacturers will find the document useful for developing the necessary labeling information, and for other unique requirements of enzyme and fluorescence immunoassay systems. This tentative guideline replaces NCCLS document DI4-P, the proposed document published in 1982.
Guideline on Disposal of Laboratory Waste The National Committee for Clinical Laboratory Standards (NCCLS) has
© 1987 Elsevier Science Publishing Co., Inc.
published a new guideline, Clinical Laboratory Hazardous Waste; Proposed Guideline (Document GP5-P). This guideline is intended to give clinical laboratorians a thorough overview of the reasons, regulatory and otherwise, for controlling laboratory-generated hazardous wastes, along with specific handling techniques and disposal methods for the primary kinds of waste. It includes a discussion of the legal background, touches on many aspects of the large field of chemical waste disposal, and addresses specific requirements for infectious waste, radioactive waste, and physical waste. It also includes information on federal requirements and federal and state agencies that can help with the often difficult task of managing the waste products of medical laboratory procedures.
NCCLS documents are available for $15 a copy ($20 for overseas orders). Payment is requested in advance and discounts are available for multiplecopy orders. Further details may be obtained from NCCLS, 771 E. Lancaster Avenue, Villanova, PA 19085, (215) 525-2435.
