RT Journal Article SR Electronic T1 Quality Control in Radioimmunoassay JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 154 OP 158 VO 3 IS 3 A1 Weigand, Patricia M. YR 1975 UL http://tech.snmjournals.org/content/3/3/154.abstract AB An active quality control program is an absolute necessity to assure precision and accuracy of radioimmunoassay results. Guidelines for the initiation of an intralaboratory quality control program include a discussion of normal values and their establishment, preparation of a quality control pool, preparation and use of control charts, and the use of duplicates. The value of external surveys is also reviewed.
