The detection and avoidance of false-positive reactions in tests for rubella-specific IgM. 1976

J R Pattison, and J E Mace, and D S Dane

Serum specimens tested for rubella-specific IgM by the haemagglutination-inhibition technique may give false-positive results due to (a) storage at -20 degrees C, (b) bacterial contamination, or (c) inactivation at 56 degrees C. These false-positive reactions can be distinguished from rubella-specific IgM activity by their resistance to 2-ME.

UI	MeSH Term	Description	Entries
D007075	Immunoglobulin M	A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin.	Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM

D006385	Hemagglutination Inhibition Tests	Serologic tests in which a known quantity of antigen is added to the serum prior to the addition of a red cell suspension. Reaction result is expressed as the smallest amount of antigen which causes complete inhibition of hemagglutination.
