Radioallergosorbent Test (RAST)—Reliable Tool Or Poor Substitute?
Radioallergosorbent test (RAST) VII Ö1 1 reliable tool or poor substitute? Edward W. Hein, M.D. An in vitro method, the radioallergosorbent test (RAST) has been developed for the detection of allergen-specific antibodies of the IgE class. Review of the literature shows that in comparison to skin testing, the RAST has a high degree of correlation (60% to 90% depending on the antigen); however, this method is not as sensitive as other tests (50% false-negative). The RAST is affected by blocking antibodies (IgG), resulting in false-negative values and high levels of IgE that bind on the allergen discs, giving false- positive findings. Because of these problems, RAST is somewhat limited for use in the clinical setting. Index terms: Allergy and immunology • Radioallergosor- bent test (RAST) Cleve Clin Q 50:361-366, Fall 1983 Skin testing has been the traditional method for diagnosis of IgE-mediated allergic disorders. This bioassay is highly sensitive, cost-effective, and safe when used by experienced personnel. In 1967, Wide et al,1 in Sweden, reported a new technique capable of detecting the minute quantities of allergen-specific IgE antibodies that circulate in the serum of allergic patients. This laboratory procedure, called RAST (radioallergosorbent test), utilized a solid- phase radioimmunoassay method. During the last decade this in vitro test has been refined and is now a commercially 1 Departments of Pediatric and Adolescent Medi- available laboratory test for clinical laboratories and, in kit cine, and Allergy and Immunology, The Cleveland form, for physicians' offices.

Serological Methods in the Identification and Characterization of Viruses
CHAPTER 4 Serological Methods in the Identification and Characterization of Viruses M. H. V. Van Regenmortel Laboratoire de Virologie Institut de Biologie Mo!eculaire et Cellulaire 67000 Strasbourg, France 1. INTRODUCTION The purpose of this chapter is to present an integrated view of the various serological techniques that have been used in virology. The accent will be placed on the principles that govern each type of test and on the general applicability of the different serological techniques in all fields of virus research. In recent years, advances in serological tech niques have sometimes been applied in only one area of virology, although they could have been equally useful to workers studying other groups of viruses. No doubt this stems from the host-oriented approach that has guided the compartmentation of virology into separate fields of specialization. When it comes to serological properties, however, the similarities between animal, insect, bacterial, and plant viruses are paramount. The same immunochemical principles govern the in vitro serological reactions of all viral antigens, and much of general interest can be learned from the findings obtained with each particular group of viruses. An attempt will be made here to emphasize the general validity of specific experimental procedures. A number of recent reviews restricted to the serology of particular groups of viruses are available 183 H. Fraenkel-Conrat et al.
