Bulletin ofthe World Health Organization, 62 (2): 217-227 (1984) © World Health Organization 1984 Immunodiagnosis simplified: Memorandum from a WHO Meeting* Technologies suitable for the development ofsimplified immunodiagnostic tests were reviewed by a Working Group of the WHO Advisory Committee on Medical Research in Geneva in June 1983. They included agglutination tests and use ofartificialparticles coated with immunoglobulins, direct visual detection of antigen-antibody reactions, enzyme- immunoassays, and immunofluorescence and fluoroimmunoassays. The use of mono- clonal antibodies,in immunodiagnosis and of DNA /RNA probes to identify viruses was also discussed in detail. The needfor applicability of these tests at three levels, i.e., field conditions (or primary health care level), local laboratories, and central laboratories, was discussed and their use at thefield level was emphasized. Classical serological techniques have been used for All these tests can be carried out in laboratories that a long time for diagnostic purposes, e.g., for con- are equipped with basic instruments as well as special- firmation of clinical diagnoses, epidemiological ized apparatus (e.g., gamma counters for RIA, ultra- studies, testing of blood donors, etc. Some of these violet microscopes for IMF, etc.), which are usually techniques have been standardized to a high degree of available only in the larger, central laboratories. -

Aarthipriya5 1,2,3,4,5Senior Assistant professor Department of Microbiology, Government Kilpauk Medical College, Chennai mail id: [email protected] ABSTRACT Objectives: To test Rheumatoid factor (RF) IgM autoantibody in Patients with Rheumatoid Arthritis by various methods like latex agglutination, Nephelometer and ELISA. Comparative analysis of the sensitivity and specificity of the tests performed. Materials and Methods: The study was conducted for a period of six months from June 2018 to November 2018 in a tertiary care hospital in Chennai. 90 patients attending Rheumatology OPD or admitted in the ward with the diagnosis of Rheumatoid arthritis, satisfying the inclusion and exclusion criteria were taken up for the study. Inclusion criteria: Clinically diagnosed Rheumatoid Arthritis patient as per revised ACR 1987 classification criteria. Duration of symptoms (1yr- early (RA) 1 Yr. (Established RA). Exclusion Criteria: Those with systemic connective tissue diseases like SLE, Scleroderma, MCTD, Sjogren syndrome, those with chronic liver diseases, tuberculosis, subacute Bacterial endocarditis, Pregnancy, Lympho reticular malignancies are excluded for the study. Those with onset 16 years of age are also excluded. Under aseptic precautions about 3ml of blood was collected from each Patient. Rheumatoid factor (RF) IgM was tested for each patient by all three methods Latex agglutination, Nephelometry and ELISA. Results: IgM rheumatoid factor (RF) was detected in the sera of 90 patients with Rheumatoid Arthritis. -

Prospective Comparison of Laser Nephelometry with Standard Agglutination Techniques for Detection of Rheumatoid Factor
J Clin Pathol: first published as 10.1136/jcp.40.2.216 on 1 February 1987. Downloaded from J Clin Pathol 1987;40:216-220 Prospective comparison of laser nephelometry with standard agglutination techniques for detection of rheumatoid factor A G PRENTICE,* P HICKLING,t I C WISEMAN,* C J HOLWILL,* J NORTHWOODt From the Departments oftRheumatology, *Haematology, and IMicrobiology, Derriford Hospital, Plymouth, Devon SUMMARY IgM rheumatoid factor was assayed by three routine methods: latex fixation; haem- agglutination; and end point laser nephelometry in 69 patients with definite or classical rheumatoid arthritis and 58 patients with other non-rheumatoid arthropathies, selected prospectively according to the American Rheumatism Association clinical criteria. The operators of the assays were unaware of the clinical diagnoses. In the group with rheumatoid arthritis 75-4% were positive by latex fixation, 73*9% by haemagglutination, and 55 1% by nephelometry. In the group with non- rheumatoid arthropathies 10-4% were positive by latex fixation, 8-6% by haemagglutination, and 10-4% by nephelometry. Thus the simple and inexpensive latex fixation test was as good as the haemagglutination test, and both were significantly better than nephelometry in the laboratory = confirmation of the clinical diagnosis ofdefinite or classic rheumatoid arthritis (X2 5.40 and 4 56,copyright. and p < 0 025 and < 0 05, respectively). None of these tests was significantly better or worse than the others in producing positive results in the group with non-rheumatoid arthropathies. The diagnosis of rheumatoid arthritis is largely based complexes, which scatter a beam of light in propor- on clinical evidence and depends on the fulfilment of tion to the concentration of the antibody in the test the criteria for definite or classic disease, as described serum. -
IMMUNOCHEMICAL TECHNIQUES Antigens Antibodies
Imunochemical Techniques IMMUNOCHEMICAL TECHNIQUES (by Lenka Fialová, translated by Jan Pláteník a Martin Vejražka) Antigens Antigens are macromolecules of natural or synthetic origin; chemically they consist of various polymers – proteins, polypeptides, polysaccharides or nucleoproteins. Antigens display two essential properties: first, they are able to evoke a specific immune response , either cellular or humoral type; and, second, they specifically interact with products of this immune response , i.e. antibodies or immunocompetent cells. A complete antigen – immunogen – consists of a macromolecule that bears antigenic determinants (epitopes) on its surface (Fig. 1). The antigenic determinant (epitope) is a certain group of atoms on the antigen surface that actually interacts with the binding site on the antibody or lymphocyte receptor for the antigen. Number of epitopes on the antigen surface determines its valency. Low-molecular-weight compound that cannot as such elicit production of antibodies, but is able to react specifically with the products of immune response, is called hapten (incomplete antigen) . antigen epitopes Fig. 1. Antigen and epitopes Antibodies Antibodies are produced by plasma cells that result from differentiation of B lymphocytes following stimulation with antigen. Antibodies are heterogeneous group of animal glycoproteins with electrophoretic mobility β - γ, and are also called immunoglobulins (Ig) . Every immunoglobulin molecule contains at least two light (L) and two heavy (H) chains connected with disulphidic bridges (Fig. 2). One antibody molecule contains only one type of light as well as heavy chain. There are two types of light chains - κ and λ - that determine type of immunoglobulin molecule; while heavy chains exist in 5 isotypes - γ, µ, α, δ, ε; and determine class of immunoglobulins - IgG, IgM, IgA, IgD and IgE .
